For those of you studying for the ACS--watch this man's videos in their ENTIRETY! Both his Gen. Chem 1 final review as well as this one! I just got done taking my ACS and I'll tell you right now, some of the questions on the exam are EXACTLY like the ones shown in these videos. Like, no joke. I was tripping out. Lots of electrochemistry! Be prepared and good luck! And to the Organic Chemistry Tutor--THANK YOU MAN!
I watched the gen chem 1 and 2 review videos the day before my ACS exam and scored in the 97th percentile. Your videos have been a life saver for me through chem 1 and 2. Thank you!
Hey! I wanted to ask you a question. Was there any " Intermolecular Forces and the Liquid State/ Chemical Mixtures: Solutions and Other Mixtures " on the exam? Since he doesnt talk about it on the videos.
I didn't study for the ACS exam. Kept pushing it off. The night before I had to take my final, I watched this video on 1.75x speed. I ended up with a 149/150 on the exam!! Thank you so much!!!
@@dashiamason8136 My advice would be to watch this video, even on double speed if you have to. Double check over your notes and, most importantly, RELAX and don't sweat it! Just do your best, trust you have the knowledge in the back of your mind :)
@@saraha9540 I do the ICE table, have a stroke. I finish the ICE table, I think I'm safe. I look at the problem, the BCA table right hooks me unexpectedly.
if you have the acs in a couple hours or if you have the acs tomorrow and its really late and your watching this...go to setting and play at a speed of 1.25x The video is still watchable and you can finish it faster (well you should know this if you know about rate laws for you exam lol)
Ended up with an A in gen chem 2, this man helped me in the extra review for each part of the semester and the final, he’s very underrated and his videos were invaluable to me
I just have to say, you are incredible. I'm taking physics and chem 2 right now and you have been a very significant help in both. You are honestly one of the best tutors out there! Keep it up!
watched your two videos over chem 1 and chem 2, got a 78th percentile on it even though I needed more time, and finished the class with an A! thank you, this definitely helped. I got 47/70 correct
True story: I watched this and (pretty much) only this like 8 hours before I took the exam. I solved each of the problems with him and labeled each of the numbers for what topic they covered (example; number 20: buffers). I looked over them a few times, and more or less learned what to do with them (although I wasn't too diligent on them). I got an 80 on the exam, which was perfect for what I was going for, a B in the class, but if I had taken a bit more time just on these questions, I think I could've gotten an A on the exam, with some luck.
I just started studying for my chem two exam last night with a few of your videos and I took the exam this morning and passed with an 81%. Thank you so much for all you do. Truly appreciate my guy
Much gratitude for your video. I struggled through chem 1 and 2, but studied your videos relentlessly and received a high grade on the ACS and a B in the class! I can attest to these tutorials because even though my exam grades were on the low end of the class, I did much better on the ACS than most of my classmates. I can't thank you enough. See you in Organic Chemistry!
Tomorrow's my birthday and also my chemistry final. All hope is lost, Balancing Redox reactions has become my final tipping point. Electrochemistry sparks no memory. Tomorrow will be my single greatest failure as I enter into the crisp age of 20. Fun times are ahead.
@@alexandrapierson6240 good for u I got like 2 more years of chem. Next up is organic chem for me, along pre cal 2 math. Yh the spring is gonna be painful

I just got my ACS grade back and I got a 100 with the curve. Thank you so much for posting this video. You covered like up to 98% of what was on the ACS. For those who are going to take the ACS, I recommend y'all to watch the video and work through the example with him. I would also recommend you guys to go over dilution more.
Ferdos Abdulkader This video really helped me as a review. I think if you are doing good in your class and use this as a review you should be good. It would also help, if you went over the theory again. That's my perspective anyway. Everyone learns differently.
I just want to say thank you so much for making this video! I have been studying all day and have felt over whelmed and have been confusing myself. Your video has helped me feel more confident and prepared for my final exam tomorrow. Again genuine thanks!
YO GUYs I just took this exam and literally if you get this video you’re going to be just fine. I didn’t believe it at first but like as you go on you’ll realize the questions are SO SIMILAR like deja voo
Just took the ACS this morning... this video is a very accurate representation of the types of questions you will see on the test. Just watching this video definitely scored me a few points on the test from remembering the little tips and tricks and reviews from the video! Thanks!
Just watched this entire video on 2.5x speed, got every single problem correct, although it feels significantly easier than the ACS problems I have been doing, it def helped solidify concepts and I am grateful you are doing it, god bless. I have my ACS gen chem 2 final tmmrw and I need a perfect 100 in order to get an A in chem this semester and maintain my overall 4.0 GPA once again. From a future Dentist, thank you for all that you do!
Already went through Gen Chem 1 video and now I'm going through and doing these problems and my ACS is today at 11. Hoping for a miracle. Or of course a generous curve.
n = log(rate2/rate1) / log(M2/M1) The power of the concentration equals the log of rate 2 over rate 1, divided by the log of the 2nd concentration over the 1st concentration.
I would like to thank you for making this, I had an exam today, and I was feeling pretty nervous before it, I watched through this and did the problems, and it gave a a great confidence boost, during the exam everything clicked, and that never would have happened if I was panicking.
Thank you so much! scored in the 80th percentile from this video! I took summer chem 2 so all of the info in such a short amount of time was hard to remember but this video helped a lot
Probably spent ~5 hours watching this video and taking notes prior to my final, and some things transferred over well. Unfortunately, a lot of what I remember learning throughout the semester from my professors, midterms, and even this video, were worded very differently on the ACS final. That being said, my score put me in the 90th percentile, which I was pretty happy with. Whether or not you see a lot of questions formatted similarly to the ones in this video, the way the Organic Chem Tutor explains various concepts is very helpful!
I watched this to prepare for my gen chem 2 final exam, which uses the ACS exam. There were problems with very very similar format to the ones in this video. I recommend it for a good overview, thank you so much!
Healtheast, do you know what you got on your Gen Chem 2 ACS Exam? I have to take mine in 5 days. Also any helpful hints on what type of problems to study a lot on? Thanks!
Hi Cody. With minimal studying except for watching this video one time through, I scored an 85%. JG does a great job of hitting 39 topics that appear like this on the exam. Although I did not study as well as I could have, I know that if I spent more time mastering this review video then I could have gotten an higher score. If you look up "acs local practice exam" you can find the exam that I took in December. Hope this helps.
This is a great video and I appreciate this a lot going into my ACS exam. But I would like to add that on question #26 you have to use either the [base]/[conjugate acid] or [conjugate base]/[acid] not the [base]/[acid]. The right answer to the question if a pH of 3.17 not 8.61. You would want to find the conjugate base [F-] because there will be less work to be done since we are given the ka value for HA being 6.8*10^-4. DO this by understanding that the ions will dissociate to HF+F- HF2- Since the Acid is HF then the F- is its conjugate base. (there are too many Fs just kind of try to keep track) anyways Kw = Ka x Kb 1.0x10^-14 = 6.8x10^-4 x [F-] [F-] = 1.47x10^-11 M plug this found conjugate base in with the original acid pH = pKa + log([conjugate base]/[acid]) pH = -log(6.8*10^-4) + log(1.47*10^-11/0.755) pH = 3.17
I thought I was doing good 2 hours in.. then he said "I linked the full 7 hour video in the description, this one is a trailer" and my heart sank and the "ohh no, ohh no, ohh no no no" song from tic tok started playing in the background💀
I wish I'd discovered your fine work earlier. Since your user name said "Organic", I assumed it was only for students in organic chemistry. Thank you so much for breaking the algebra steps down as much as you do. That is my bête noire in chem class. I really appreciate your work. Thank you so much!

Hey I took my final exam today for 2nd semester gen chem and your video definitely helped me score some answers! While taking my final I wished I would have finished the entire video! Lol
In less than two days, I will be having a Chem II final and a Calc II final. You’re saving my ass for both. GOOD LUCK TO EVERYONE STUDYING FOR AN EXAM!! WE GOT THIS!!
Update 1: 4 hours later and I think I got this video down. Off to your Calc 2 review! You do not understand how much I love you, you’re literally the only reason why I haven’t dropped out yet. I’m sure many other students feel the same!! Thanks for making finals week less stressful than it could have been ❤
@@7aurent It’s been a while so I don’t remember all of the topics covered on my final exam, but I do remember this video being really helpful. There were questions beyond the scope of this video, but you should still at least understand this video first because it covers so much fundamental concepts. As for the calculus 2 review, I just searched for his “Calculus 2 Final Exam Review,” and also his long video on the geometric series, p-series, ratio test, etc. I did buy membership to unlock the more detailed versions though, those came with more examples but the free videos were super helpful too. You should be fine if you can get those concepts down. Good luck with your exams!!
I should have been using this from the start. Once you get halfway through the video he shares the link for the longer video (7hours). I wish I would have used this rather than the ACS workbook. This also would have been great to use as a practice tool throughout the semester. Thank you "The Organic Chemistry Tutor" for making such a thorough video. I will be using your organic chem videos next.
vimeo.com/ondemand/genchem2finalreview For anyone wondering, that's the link to the 7hr version. It does cost $50+ to watch, but it might be worth it if anyone feels really doomed for Chem...
Just took the acs exam this week and this video does a decent job at preparing you for the acs exam. The ACS exam had like 5 questions about heat of fusion questions and 2 questions about solids, got a 67%(before the curve) after watching this video and studying all the chapters. This is coming from a student who had a 96,96,100 on the three exams for the exams and refused to buy the acs book. So to anyone in the future that needs to do well on the acs exam, buy the book. I choose not to because I had wiggle room to mess up and still ace the class.
Hey! I wanted to ask you a question. Was there any " Intermolecular Forces and the Liquid State/ Chemical Mixtures: Solutions and Other Mixtures " on the exam? Since he doesnt talk about it on the videos.
It’s almost 4 am-I have my Chem 2 final at 10;30 am tomorrow morning (I took tonight off to study but didn’t wake up until 7pm today so my digital studying is happening now). I’m writing this on my 5 minute study break from the video. Thank you so much for the guide.
Thank you so much for this!!! It’s so helpful and really dumbed down the acs practice questions for me! I’m gonna destroy this exam now!! But I have a suggestion for this video that I think can really help! Can you put the times in your description for each subject so students who are struggling in a certain part of the course can instantly jump to the examples and not have to scroll through? It’s something minor but I think it can really help!!!! :D
Watched your chem 1 and this one to its entirety... I have the acs exam for gen chem 2 tommorrow just wanna say thanks for making this... this is literally gonna be the reason I do good.

@@ksingh6756 this was a good review and study material. I would recommend going through your ap chem textbook and then watch these 2 videos to better understand the material. Good luck!
This legend carried me through ACS for gen chem 1. Here I am a night before the exam with barely any time to study besides this video. Let’s hope I get carried once more for gen chem 2 ACS
i got a 52/70 on my ACS exam after only watching this video!! if you study anything for the test, WATCH THIS VIDEO. my ACS score at my uni curved to an 87%! can’t recommend this video enough.

Lol yeah same actually 8 am est
For those of you studying for the ACS--watch this man's videos in their ENTIRETY! Both his Gen. Chem 1 final review as well as this one! I just got done taking my ACS and I'll tell you right now, some of the questions on the exam are EXACTLY like the ones shown in these videos. Like, no joke. I was tripping out. Lots of electrochemistry! Be prepared and good luck! And to the Organic Chemistry Tutor--THANK YOU MAN!
Alex Cañas like what questions?? Any additional info ?? Pls. I'm taking 2nd semester ACS in two days :x
I'm taking it in 9 hours and watching it right now. LOL
Uh any tips for me? I got it in 4 days
im taking it tomorrow :(((
Wait you watched the one for gen chem 1 for the gen chem 2 ACS?
I watched the gen chem 1 and 2 review videos the day before my ACS exam and scored in the 97th percentile. Your videos have been a life saver for me through chem 1 and 2. Thank you!

I didn't study for the ACS exam. Kept pushing it off. The night before I had to take my final, I watched this video on 1.75x speed. I ended up with a 149/150 on the exam!! Thank you so much!!!
congrats!! any advice?
@@dashiamason8136 My advice would be to watch this video, even on double speed if you have to. Double check over your notes and, most importantly, RELAX and don't sweat it! Just do your best, trust you have the knowledge in the back of your mind :)

It's that time of the year again.. cramming the night before for chem
You might be in the wrong major if your cramming before your science exams 😂
Today's the day. Do your best, everyone.
if you have the acs in a couple hours or if you have the acs tomorrow and its really late and your watching this...go to setting and play at a speed of 1.25x
The video is still watchable and you can finish it faster (well you should know this if you know about rate laws for you exam lol)
Ended up with an A in gen chem 2, this man helped me in the extra review for each part of the semester and the final, he’s very underrated and his videos were invaluable to me
ya same bc of his videos I have a 99.6% before gen chem 2 final and im sure this video will prepare me
Who has the ACS within 72 hours like me
Mine's in a few hours
Cody Smith mostly concept
Mine is in 24 hrs...
Yeah, if you want a good overview, then this video helps
Was the material in this video what was on the test?
I just have to say, you are incredible. I'm taking physics and chem 2 right now and you have been a very significant help in both. You are honestly one of the best tutors out there! Keep it up!
watched your two videos over chem 1 and chem 2, got a 78th percentile on it even though I needed more time, and finished the class with an A! thank you, this definitely helped. I got 47/70 correct
You're very welcome
How similar were the videos to the test?
True story: I watched this and (pretty much) only this like 8 hours before I took the exam. I solved each of the problems with him and labeled each of the numbers for what topic they covered (example; number 20: buffers). I looked over them a few times, and more or less learned what to do with them (although I wasn't too diligent on them). I got an 80 on the exam, which was perfect for what I was going for, a B in the class, but if I had taken a bit more time just on these questions, I think I could've gotten an A on the exam, with some luck.
Was this for the final or nah? Bc on the acs final they made it both gen chem 1 and 2
This was the final for my class, but on this exam, they were only testing gen chem 2, if that’s what you’re asking

Much gratitude for your video. I struggled through chem 1 and 2, but studied your videos relentlessly and received a high grade on the ACS and a B in the class! I can attest to these tutorials because even though my exam grades were on the low end of the class, I did much better on the ACS than most of my classmates. I can't thank you enough. See you in Organic Chemistry!
Watched this video the night before my acs exam and got a 95, thanks!
I am proper shook at the quality of ALL of your videos!!!!
Tomorrow's my birthday and also my chemistry final. All hope is lost, Balancing Redox reactions has become my final tipping point. Electrochemistry sparks no memory. Tomorrow will be my single greatest failure as I enter into the crisp age of 20. Fun times are ahead.

THANK YOUUUU doing god’s work fr
Thank you! I've been taking General Chemistry pt2 running from August-December and semester cumulative finals are so brutal.
8:39 pm, test due by midnight and I just started watching this. Gotta love life
Chem 2 final is 4/29/2024
Exam 1: 60%
Exam 2: 70% with black magic
Exam 3: 45% O_O
Quiz average: 90ish percent
Attendance rizzing, Homework maxxing, Checkup grinding. I pass on a 55% or higher
We are in a very similar position my friend good luck
howd u do??
I just got my ACS grade back and I got a 100 with the curve. Thank you so much for posting this video. You covered like up to 98% of what was on the ACS.
For those who are going to take the ACS, I recommend y'all to watch the video and work through the example with him. I would also recommend you guys to go over dilution more.
Its so interesting seeing the many different replies on this and how many people said they did horrible
Ferdos Abdulkader This video really helped me as a review. I think if you are doing good in your class and use this as a review you should be good. It would also help, if you went over the theory again. That's my perspective anyway. Everyone learns differently.

Already went through Gen Chem 1 video and now I'm going through and doing these problems and my ACS is today at 11. Hoping for a miracle. Or of course a generous curve.
n = log(rate2/rate1) / log(M2/M1)
The power of the concentration equals the log of rate 2 over rate 1, divided by the log of the 2nd concentration over the 1st concentration.

Probably spent ~5 hours watching this video and taking notes prior to my final, and some things transferred over well. Unfortunately, a lot of what I remember learning throughout the semester from my professors, midterms, and even this video, were worded very differently on the ACS final. That being said, my score put me in the 90th percentile, which I was pretty happy with. Whether or not you see a lot of questions formatted similarly to the ones in this video, the way the Organic Chem Tutor explains various concepts is very helpful!
FINAL EXAM TOMORROW MORNING
only channel i willingly watch the ads because I appreciate this channel so much
I watched this to prepare for my gen chem 2 final exam, which uses the ACS exam. There were problems with very very similar format to the ones in this video. I recommend it for a good overview, thank you so much!
Healtheast, do you know what you got on your Gen Chem 2 ACS Exam? I have to take mine in 5 days. Also any helpful hints on what type of problems to study a lot on? Thanks!
Hi Cody. With minimal studying except for watching this video one time through, I scored an 85%. JG does a great job of hitting 39 topics that appear like this on the exam. Although I did not study as well as I could have, I know that if I spent more time mastering this review video then I could have gotten an higher score. If you look up "acs local practice exam" you can find the exam that I took in December. Hope this helps.
This is a great video and I appreciate this a lot going into my ACS exam. But I would like to add that on question #26 you have to use either the [base]/[conjugate acid] or [conjugate base]/[acid] not the [base]/[acid].
The right answer to the question if a pH of 3.17 not 8.61.
You would want to find the conjugate base [F-] because there will be less work to be done since we are given the ka value for HA being 6.8*10^-4.
DO this by understanding that the ions will dissociate to HF+F- HF2-
Since the Acid is HF then the F- is its conjugate base.
(there are too many Fs just kind of try to keep track)
anyways
Kw = Ka x Kb
1.0x10^-14 = 6.8x10^-4 x [F-]
[F-] = 1.47x10^-11 M
plug this found conjugate base in with the original acid
pH = pKa + log([conjugate base]/[acid])
pH = -log(6.8*10^-4) + log(1.47*10^-11/0.755)
pH = 3.17

Got an A in Chem 102 man, I got a C last time around so it's a massive improvement from then.
Thank you so much
Hey I took my final exam today for 2nd semester gen chem and your video definitely helped me score some answers! While taking my final I wished I would have finished the entire video! Lol
I have watched so many honey adds for this dude.... Eternally grateful!!!
In less than two days, I will be having a Chem II final and a Calc II final. You’re saving my ass for both. GOOD LUCK TO EVERYONE STUDYING FOR AN EXAM!! WE GOT THIS!!
Update 1: 4 hours later and I think I got this video down. Off to your Calc 2 review!
You do not understand how much I love you, you’re literally the only reason why I haven’t dropped out yet. I’m sure many other students feel the same!! Thanks for making finals week less stressful than it could have been ❤
wait i also got my chem 2 and calc 2 final this week, did you pass both ?
@@jonathansaravia2877 Yup! I ended up passing Calc II with a B and Chem II with an A-！
Good luck with your exams!!
@@kysuneh how useful was this video anything i should look out for and what video did u watch to help study for calc 2?
@@7aurent It’s been a while so I don’t remember all of the topics covered on my final exam, but I do remember this video being really helpful. There were questions beyond the scope of this video, but you should still at least understand this video first because it covers so much fundamental concepts. As for the calculus 2 review, I just searched for his “Calculus 2 Final Exam Review,” and also his long video on the geometric series, p-series, ratio test, etc. I did buy membership to unlock the more detailed versions though, those came with more examples but the free videos were super helpful too. You should be fine if you can get those concepts down. Good luck with your exams!!
Today I had Exam. Your videos were very helped me. I think the most question is related to your lesson. Thank you very much.
I should have been using this from the start. Once you get halfway through the video he shares the link for the longer video (7hours). I wish I would have used this rather than the ACS workbook. This also would have been great to use as a practice tool throughout the semester. Thank you "The Organic Chemistry Tutor" for making such a thorough video. I will be using your organic chem videos next.
wait, when do you see the link for the 7hour one ?
vimeo.com/ondemand/genchem2finalreview
For anyone wondering, that's the link to the 7hr version. It does cost $50+ to watch, but it might be worth it if anyone feels really doomed for Chem...
I passed the course and survived the final using your videos, thank you very much! Much love
acs exam is in an hour and a half, wish me luck and good luck to everyone else also taking it today
Just wondering did it help?
you really helped me, and I'm sure many students with this video.
I wish you all the best in your academic career.
thank you!
Just took the acs exam this week and this video does a decent job at preparing you for the acs exam. The ACS exam had like 5 questions about heat of fusion questions and 2 questions about solids, got a 67%(before the curve) after watching this video and studying all the chapters. This is coming from a student who had a 96,96,100 on the three exams for the exams and refused to buy the acs book. So to anyone in the future that needs to do well on the acs exam, buy the book. I choose not to because I had wiggle room to mess up and still ace the class.
If anyone is taking the ACS 2nd semester gen chem final you need the know that most of he exam was on kinetics and buffers and mixtures!
Acids and bases*
Hey! I wanted to ask you a question. Was there any " Intermolecular Forces and the Liquid State/ Chemical Mixtures: Solutions and Other Mixtures " on the exam? Since he doesnt talk about it on the videos.
ive got my ap chem exam tmr TT not ready at all but hope all goes well, and for anyone else taking it!
I have a Gen Chem 2 final exam, thanks for this content to help me study with!
Lol I love when you look at the stats on this video there was a huge spike in views the last few days. And yes my ACS final is tomorrow haha
So is mine lol
I just wanna know how you get an ACS final in the middle of february
Lyla loving this
It’s almost 4 am-I have my Chem 2 final at 10;30 am tomorrow morning (I took tonight off to study but didn’t wake up until 7pm today so my digital studying is happening now).
I’m writing this on my 5 minute study break from the video. Thank you so much for the guide.
I read the comments and decided to start studying 2.5 weeks out from my first chem 2 exam. Wish me luck guys, I've always sucked at chem.
Here is my chemistry video playlist which can help you:
th-cam.com/video/bka20Q9TN6M/w-d-xo.html
Took my gen chem 2 final and got an 86!!! I watched the gen chem 1 video as well!
Thank you so much for this!!! It’s so helpful and really dumbed down the acs practice questions for me! I’m gonna destroy this exam now!! But I have a suggestion for this video that I think can really help!
Can you put the times in your description for each subject so students who are struggling in a certain part of the course can instantly jump to the examples and not have to scroll through?
It’s something minor but I think it can really help!!!! :D
Watched your chem 1 and this one to its entirety... I have the acs exam for gen chem 2 tommorrow just wanna say thanks for making this... this is literally gonna be the reason I do good.
I had my ACS exam today, already finished it, and I'm just finding this video now....
Hey! I wanted to ask you a question. Was there any " Intermolecular Forces and the Liquid State/ Chemical Mixtures: Solutions and Other Mixtures " on the exam? Since he doesnt talk about it on the videos.
Because of this video I made a B. Straight up. Thank you so much.
Got covid symptoms before gen chem 2 ACS finals and couldn’t sleep all night.. currently 4am, test at 8am watching this video in hopes to pass 🥹🫡😷 goodluck everyone!
Did u
Just did my ACS final, scored in the 98th percentile! All I did was watch these two vids and do my teacher's study guide. This guy's great!
Congrats! Hope I can do anywhere near as good as this tomorrow lol

@@jonesjones6279 what did most of the questions focus on?
Dinore Gashi I’d say as long as you know your Intermolecular forces, thermodynamics, equilibrium, and rate laws well you could easily make a B on it.
@@jonesjones6279 Thanks so much!!!
I'm deaf and can't hear your voice. Please add Closed Caption on your video in General Chemistry and the rest of them. Thank you!
just turn up the audio
Anonymous gottem
dog omg wtf
Thank you for making this. I watched only this video the night before and ended up doing extremely well on the ACS exam.
I learned more stuff in these 2 videos than what my AP Chemistry teacher taught me all year. This really helped, I have my AP exam tomorrow.
How did you do?
@@samanthabrown1617 Got a 4 on it and didn't have to take the class in college 😁
@@tommykaratee just with these 2 vids ? have AP chem on 2nd
@@ksingh6756 this was a good review and study material. I would recommend going through your ap chem textbook and then watch these 2 videos to better understand the material. Good luck!
@@tommykaratee thankyouu
Currently watching this hours before the AP test, wish me luck, I just got through the general chemistry 1 vid. I’ll update y’all with my score
how did you do!
Got the AP exam tomorrow... I wanna die

I watched this video the night before and got a 95 on my final!!! :)
I have to take this in 2.5 hrs... haven't studied... here we go
I hope you did well.
how was it?
hahaha
This legend carried me through ACS for gen chem 1. Here I am a night before the exam with barely any time to study besides this video. Let’s hope I get carried once more for gen chem 2 ACS
ACS in less than 19 hours
I legit wish I had known this guy at the beginning of my gen chem class.
Heyy to all those writing the exam tomorrow.. We will be finee🙏🙏
You are a life saver. Thank you for doing these videos my friend.
