chem final in a few hours lol its 2 am and this man has helped me with everything in chemistry big love to you man keep doing what you are doing because you hare helping kids everyday pass classes and help them achieve their goals. You are the best, thank you and I hope to meet you one day
Simo Valentino same lmao 2:13 AM ab to take a chemistry final
Simo Valentino go to bed!
@@christinarose2877 go to bed and fck yourself
1:25 AM
4:16AM
i already learned more in this video than what my teacher taught in a whole unit
Suchith Munigati My teacher SUCKS!!!
Same here.hahaha
Exactly
Fact
Yes
You have literally taught me every engineering course for grade 12, god bless you sir
God bless you!! i am a tutor and could not get this figured out but watching your videos has saved me!!!!!!!!! thank you for taking the time to create these
Ashley Kane you are so humble! I like that
thank you Ashley, same here, you're not alone !!!
you are the best! I had no idea what my professor was doing. After watching this and a couple of your other Thermochemisty videos I was able to get all of my homework done easily! PS. your videos helped me the entire semester, I am standing at a solid A going into finals thanks to your videos!
Respect this creator for actually contributing to TH-cam and Internet with knowledge and incite!
Great video, thank you. Your sig figs are a mess but I still fwu
also what I thought
Carson k sig figs make it easier for scientists to calculate things in a hurry to get a good estimate
Sig figs is just the perpetuation of useless shit.
Thank you so much for remaking the video! The last video was kind of hard to watch when the question was missing with the steps.
I was so lost when my professor was teaching thermochemistry and reading the textbook. Thank you so much for going over the problems and doing videos like this.
Omg i frickin love you dude, my chem teacher is great but I hardly understand what he says and it’s not his fault. An this whole online thing is killing me but you have literally taught me everything I need to know and it’s not even a live session. You’re the best and keep doing exactly this because it really helps, it really really does
felt this, my chem teacher is just throwing work at us and nothing from the lectures relates back to the exam material.
i like all of your videos, you know how to simplify complicated information .. thank you man!
We'll have a summative test in general chemistry hours later, so this is a very big help, especially when these calculations and explanations are all left out by the teacher in the lecture yet included in the test. That teacher have high standards I tell you
i’m a sophomore in honors chemistry in high school, and my teacher doesn’t really teach in a way where the class is able to follow what she is saying. The final is tomorrow, and this man has taught me anything i needed to know, that i didn’t get from my teacher. Thank so much.
Professor Organic Chemistry Tutor, this is a lengthy and awesome video/lecture in AP/General Chemistry on Calorimetry Problems. The Calorimetry problem selection are excellent from start to finish. This is an error free video/lecture on TH-cam TV with the Organic Chemistry Tutor.
learned more by 1:23 than from watching my teacher's videos over and over for a half an hour. THANK YOU!
Love this man thermochemistry just as a title for a chapter is so daunting omg
I have been struggling for with final temperature so badly. And they way you just explained is going to help me succeed so much!
You’ve contributed to my continued interest and success in chemistry. Thank you ✊
Besides chemistry, I also learned math from this channel.. whenever exam or quiz around the corner and I didn't have time to understand everything my lect teached before, I'll definitely come here..thanks to you, I manage not to look too stupid. I understand better here❣️❣️
I think I found this channel struggling to learn math. I was so stoked to realize he does Chem and Bio videos as well. He’s such a blessing!
Funny cos the video is titled chemistry yet it deals with subject of maths and physics, I guess you get all 3 out of this
@@nikitasichov5390 yeahh..it saves a lot of times..coz I don't need to find another channel
@@izzazi01 No, I'm talking about the video
Bro, I really can't thank you enough for these videos. Please keep doing what you do!
well this is much more helpful than my teacher's demonstration and notes of this. Thank you!
OMG sameeee
couldn't have said it better myself
Thank you, these videos are a lifesaver!
thank you so much dude, this 30 minute video made me understand the topic way more
For every module in my chemistry class I have to come watch your videos in order to better understand. Thank you!!!! NO shade to my professors, but some people just have a knack for teaching... Plus your voice is soothing lol...
grabe ano nalang if wala ka, di ko talaga maiintindihana ang genchem I LOVE U THANK UU
My teacher is typically good at teaching chem stuff, but for some reason I just can't understand this unit, even when she goes over everything. I tried asking her for extra help but she gave me a really vague answer for some reason and then just said I was getting too distracted (despite immediately coming up with actual times for other students who asked, including my friend who sits right next to me and is equally distracted). But besides that, thank you so much for this video (and entire channel). It always helps me whenever I don't know what to do.
A life saver !! I wouldn’t have passed without you 😢🎉🎉❤thank you
YOU THE REAL MVP MAN
Chem finals tomorrow and you help me understand this thank you 🤝
One of the easier topics in chemistry. So straight forward, very satisfying to do.
ouch Dawson, I struggling
@@cosettedunkle2362 me too man
chemistry is gay
Best chem tutor on TH-cam
Thank you so much bro. Clear and concise. What we like to see
Life time sub from now on wete in this stage of class and with Jess law and it's all kind of joined together and having trouble diffentiating , teacher misses the mark sometimes so this is great, you have videos for both things,do u have a chemistry degree how are you so good at the stuff, I hope you make money from This cause you help thousands of people and deserve it
Very good video, indeed I tried the last video but was not sure. But it has a silly mistake I made that make my entire answer wrong. Very helpful
This helped me a lot,thank you so much!
Helpful video. You know what would make it more helpful, though? Adding in some ASMR :) Your voice is really relaxing 😌
without u i do not know where i would be thank you sir
Holy shit! I know this is late but jesus man, thank you! You made this so much easier to understand!
This really, really, really helped me. Thank you!! :D
This was such a big help on my homework and I might actually do good on my quiz tmr!
Howd it gooo, I have a test tmr hopefully I do.... ugh its 2:07 am lmaooo
Hey btw you are amazing! I honestly love how smart you are but how everything you upload is so learnable! ❤️❤️❤️❤️❤️😁
I aced my chem test. Thanks to you
I'd actually be good at chem if I had mark wahlberg as my professor
Whattt!?? How?
bro has single handedly saved my entire chem grade
I don't how can I Thanks from you
Thanks alot your videos really help me to know about my lesson more .
❤❤❤🌻🌻👍
Appreciate this stuff a lot man. Kudos
sicks days got me bad, thanks for helping me catch back up to my Chem class.
This the best teacher so far.Do you all agree😊?????
love this pls continue with what you are doing .this has really helped me sir.
This dude is a certified GOAT, he’s gotten me through freshman Math and now he’s bout to get me through both Chemistry and sophmore math
yo do you know where i can find his math vids?
@@Fwbaji2.0 just search up the topic and you’ll find a video
I wish I could have you as my chem prof (or any other science class tbh)
Top 10 tutorial moment of all tine thx
Great video as always
Thanks so much you are the best teacher ever 🌹👍
Your videos are awesome. Keep it up
Currently my only chem teacher!
This video is like super old but this is helping me sm thank you
actually its getting more older now,.
do you take the mass of the solution or the mass of water when calculating Q(soln) cause in one of the vids you took the mass of the entire soln. Am confused now????!!
You’re a life saver ❤️
This really help me much towards my test.thanks much sir ❤❤❤
istg i'd do everything this guy wants in exchange for helping me pass grade 12. thank you!
that kJ/mol in the last problem caught me offguard
for the problem at 14:00 shouldnt the mass used be (2.6+260 grams) instead of 260
you would still divide by the moles of CaCl2
Just aced my quiz cuz of this guy. Alhamdulilah
Thanks. I'm still a bit confused but the onus is on my professor, who hasn't introduced any of these terms or formulas to us and just linked us to this video. It's pretty discouraging how lazy some teachers have become, not even providing the basic tools for students.
I have a good feeling you're going to save my chemistry grade this semester
Excellent video.
thx.this helped me for homework
this really helped me
So helpful!
7:46 god I was JUST struggling with a problem like this. Thank you sm
appreciated man!
Very helpful 😊
very informative lecture dude
Very helpful
i love u so much u are my life saver
Thank you so much this video is insanely good. Much appreciated man
Man, why does my chem prof make this seem so complicated
dude I swear no one can teach like this guy
Are the units in the last question joules or joules per minute?
lovely. errors fixed.
this was so helpful tyvm !!!
u sound like a minecraft villager. That is the greatest compliment you could ever receive.
I luv u organic chemist cx
Watching this an hour and a half before my midterm lol
mines in 9 mins 💀💀
@@jackissupercoolandstuff Good luck!
same before my final tho lmao
@@sofiaahnen5076 I hope you do well on it
THANK YOU!!!!!!
MOst of the comments here say that this video learn us a lot more than our teachers. I am kind of agreed with this.
At 14:31 dint you have to use the total of g in the system the 260 plus the 2.6?
I ended first semester chem H with a 71% and only cus my lab group is smart and got As in every lab. I got Ds and Fs on every quiz and test. im not even exaggerating. fml
Where did the enthalpy of reaction formula at 18:00 come from/what is it derived from?
THANK YOU
thank you 🐐
mad respect
YOU. SAVED. MY. ASS.
Thank you!
19:47 BTW, the specific heat of ice is 2.1 j/g Celsius, and the specific heat of steam is 1.7 j/g Celsius. (Just in case of any confusion) Also, yeah, the sig figs here are VERY WRONG, but this video is a great basis to help you study. As long as you do your own rounding and calculations.
perfect example for latent heat and phase change at : 19:44
your my friend now
you the plug
Thank you sir
for the question at 8:00 does it matter which one gets the negative sign because I can understand why Fe gets a negative since it is losing heat but I'm wondering if it would make a difference in the final answer, mathematically.
Ibrahim Malki he said that it does not matter. I tried it by putting the sign in any one of them and I got the same answer.
