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!
@@thatroseme 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
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 have literally taught me every engineering course for grade 12, god bless you sir
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.
You’re a sophomore learning this? That’s incredible. Kudos to you.
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.
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!
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.
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.
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
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
Respect this creator for actually contributing to TH-cam and Internet with knowledge and incite!
I put too much time into my other classes which had the side effect of neglecting chem, so now the tables have turned and chem is the class I’m trying to catch up on.. This is super important for me to understand as a ME major because we take an entire, upper-level course on thermodynamics and another on heat transfer specifically. Idk how id survive this major without the excellent, free resources available online like this channel
learned more by 1:23 than from watching my teacher's videos over and over for a half an hour. THANK YOU!
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.
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
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.
messy sig figs are better. no one cares about sig figs outside of professors for tests. bigger number without rounding means less errors irl
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.
Love this man thermochemistry just as a title for a chapter is so daunting omg
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
grabe ano nalang if wala ka, di ko talaga maiintindihana ang genchem I LOVE U THANK UU
I have been struggling for with final temperature so badly. And they way you just explained is going to help me succeed so much!
Chem finals tomorrow and you help me understand this thank you 🤝
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...
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
This the best teacher so far.Do you all agree😊?????
You’ve contributed to my continued interest and success in chemistry. Thank you ✊
i like all of your videos, you know how to simplify complicated information .. thank you man!
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
At 15:52 why can't you combine the masses of water and CaCl2 and calculate the q of the combined solution?
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.
my chem teacher and my class is literally useless. just absolute dog. nothing of value. your videos on thermochemistry have narrowed down about 3 days of tedious classtime into one hour of solid studying and learning. so, thank you so much
MOst of the comments here say that this video learn us a lot more than our teachers. I am kind of agreed with this.
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.
bro has single handedly saved my entire chem grade
thank you so much dude, this 30 minute video made me understand the topic way more
YOU THE REAL MVP MAN
A life saver !! I wouldn’t have passed without you 😢🎉🎉❤thank you
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
I'd actually be good at chem if I had mark wahlberg as my professor
Whattt!?? How?
Currently my only chem teacher!
without u i do not know where i would be thank you sir
istg i'd do everything this guy wants in exchange for helping me pass grade 12. thank you!
Best chem tutor on TH-cam
I aced my chem test. Thanks to you
that kJ/mol in the last problem caught me offguard
sicks days got me bad, thanks for helping me catch back up to my Chem class.
Bro, I really can't thank you enough for these videos. Please keep doing what you do!
Watching this an hour and a half before my midterm lol
mines in 9 mins 💀💀
@@Miniluvsyou Good luck!
same before my final tho lmao
@@sofiaahnen5076 I hope you do well on it
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
Pfp a slayy
u sound like a minecraft villager. That is the greatest compliment you could ever receive.
7:46 god I was JUST struggling with a problem like this. Thank you sm
I wish I could have you as my chem prof (or any other science class tbh)
Top 10 tutorial moment of all tine thx
Just aced my quiz cuz of this guy. Alhamdulilah
Helpful video. You know what would make it more helpful, though? Adding in some ASMR :) Your voice is really relaxing 😌
chem finals in 30 mins i'm sorry i have failed you man
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
Thank you, these videos are a lifesaver!
I have a good feeling you're going to save my chemistry grade this semester
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 really help me much towards my test.thanks much sir ❤❤❤
You’re a life saver ❤️
love this pls continue with what you are doing .this has really helped me sir.
perfect example for latent heat and phase change at : 19:44
I don't how can I Thanks from you
Thanks alot your videos really help me to know about my lesson more .
❤❤❤🌻🌻👍
At 14:31 dint you have to use the total of g in the system the 260 plus the 2.6?
Holy shit! I know this is late but jesus man, thank you! You made this so much easier to understand!
For the question at 12:52 would you add the mass of the CaCl2 to the mass of water because it is soluble?
This video is like super old but this is helping me sm thank you
actually its getting more older now,.
Thanks so much you are the best teacher ever 🌹👍
Man, why does my chem prof make this seem so complicated
dude I swear no one can teach like this guy
Thank you so much bro. Clear and concise. What we like to see
15:52 what does he mean by anytime the temperature of the solution goes up that tells you the reaction is endothermic, if the temperature of the solution went down the reaction would be endothermic? I'm so confused at this part please help!
Endothermic means that the reaction gained heat and so the temperature of the solution would increase.
Exothermic means that the reaction lost heat and so the temperature of the solution would decrease.
For you in two years ago. I think its his error he made. He supposed to say "by anytime the temperature of the solution goes up that tells you the reaction is EXOthermic, if the temperature of the solution went down the reaction would be endothermic"
Furthermore, If the temperature of the solution increase, the reaction must release energy so its exothermic in order to raise the temperature for the water, thus, the water absorbs heat which become endothermic for the water.
this is the good method of learning, can schools just put effort into trying to find the best method for students to learn???? or are they sticking to their very old ways smh
at this second, 25:55 why did you multiply and not divide the joules by the grams i think that what should you done :)
may be I am wrong i am just unsure
You are super helpful thank you ❤
Would you mind If you foccus on sig fig on the final answer please 🙏🏾❤️
Chem teachers at uk should take notes
At 15:51, I heard "so any time the temperature of the solution goes up that tells you the reaction was endothermic; if the temperature of the solution goes down the reaction would be endothermic." Did you mean exothermic for when the temperature of the solution goes down?
I hope that's what he meant! Otherwise, I'm thoroughly confused.
Here’s a helpful way I remember. Endothermic (Endo- en= enter) heat entering. And exothermic. Ex= exit. Heat leaving.
Jack Johannessen yes
no, he is right!! , whenever something reacts in Water if its endothermic( it absorbs Energy special case a salt in Water: the lattice Energy is higher than the Hydration energy) the Water has to give Energy (heat) to Reaction, so it will make the Water cold( Water gave heat , so Exothermic) the Reactant absorbed Energy so Endothermic!
Naku Chan ty furry
Where did the enthalpy of reaction formula at 18:00 come from/what is it derived from?
Your videos are awesome. Keep it up
I luv u organic chemist cx
the people who unliked this prepared something we weren't ready for
I don't know if this is too late but for the problem asking for the enthalpy change why wouldn't you add the mols of CaCl2 and H2O? You're finding the enthalpy change for when CaCL2 dissolves in water so why leave the mols of the water out?
this really helped me
This helped me a lot,thank you so much!
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????!!
your my friend now
Hey btw you are amazing! I honestly love how smart you are but how everything you upload is so learnable! ❤️❤️❤️❤️❤️😁
i love u so much u are my life saver
thx.this helped me for homework
For the problem at 14:18 why did you calculate the q of h2o instead of the q of the solution assuming the same properties as water (using 262.2g)?
This is what I'm wondering too
I think he is wrong? Cuz my chem professor uses the mass of the entire solution (262.2g) for problems like these
Thank you Dutch man
At 15:51 you said, "any time the temperature of the solution goes up, that tells you that the reaction was endothermic, if the temperature of the solution went down, the reaction would be endothermic..." which one is it bro
Appreciate this stuff a lot man. Kudos
Almost numerical part has been
Covered and very much helpful to me, thank you sir.
Great video as always
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.
Hello! Its a great video and I learned a lot. Thank you! But I just want to clarify the last part. (1.33)(40.7)(1000)=54131J so the total Q would be Q=80,399J.
Hi Kai! I just want to make a correction to your point as this can confuse other students. So, The Tutor is actually correct. It is 54266.7 and not 54131.
The thing is you rounded off 1.333333 into 1.33. As you can observe, he calculated it straight without rounding off 1.33. No hate please.
In short,
(1.3333333)(40.7)(1000)=54266.7J
Hope it helps!
