You’re literally a legend. This deserves millions of views bro

[@alisgevorgyan3891]

100000%

[@minestrone3]

Thank you for putting so much of your time into making these helpful videos and even including a hand-out to go with the video. You have a gift for explaining difficult concepts in a plain and clear way. Thank you very much indeed.

[@particleex6428]

For question 14 (48:57), that was a BEAUTIFUL explanation (to understand exothermic reactions in relation to one another)

[@heartcomedy5]

Thank you so much. I literally sat down and studied the questions from your video for hours, taking notes, trying it on my own, etc. This was a huge help.

[@zs2839]

love your way to explain chemistry problems

[@paigesernowski2706]

thank you, you literally saved my life I thought I was gonna fail but this helped me so much

[@qaesar09]

Thanks man, have a Thermodynamics final this coming Tuesday, hopefully this helps.

[@moneneal2517]

Saved my life thank you kind sir

[@addiej5497]

I love your attitude!

[@dasireddyrohitreddy3618]

my man you took so much time and made it worth my time too.
the only bad thing is that for so much time of hardworking you get only 2.5k views,
you should get around 1 billion views, i think i am gonna be a hacker and get you the billion views

[@Trump_Gaming]

So, how did your chemistry test go 2 years ago? Have you decided to pursue a career in computer science and fulfill you dreams of becoming a hacker?

[@syahfA1]

Keep going make contents like this sir. This help me a lot since I dont ever get to understand this before until I found your channel. Thankss soo much

[@faridisayev1570]

No any comment. The moment when explanation and everything is perfect! Thanks for this great video.

[@UriValdez]

This is about the best video for Thermochemistry. Its easy to follow and understand. Thanks a bunch man

[@alisgevorgyan3891]

Cool COOL
Love this so so much, perfect for IB chem students!
Thank you

[@theeargasmchannel]

this man is a hero istg

[@uchizi_zm]

Thank you so much. Your explanations are so clear and easy to understand.

[@firebloom02]

You are much appreciated for this video

[@Kashish50]

Thankyou so much you are the best teacher the way you teaches makes me understand everything

[@sarahcoogan3565]

Amazing video! Thank you so much! :)

[@safesoundequine8511]

you are an absolute hero

[@shinobiscorch]

Just making sure I have my knowledge right but on question 6 at 14:06 is the answer suppose to be 0.00979 and not 0.0979?

[@Bia-starlight]

I very much agree on this. I think it's 0.00979.

[@candicetaylor1478]

Thank you so much! This has been super helpful. I am wondering tho, question 6 around 14 minutes in, the question is only asking for the Enthalpy change, but you have given us the formula for Molar Enthalpy (Q/n) Is this just an extra step you've shown, or are we supposed to get down to the per mole here??

O.M.G. THIS SAVED MY ENTIRE LIFE.

[@chemistNATE]

That’s great ! I have always wondered if people like this particularly long video.

[@Bia-starlight]

My exam is tomorrow morning. Yikes. But thank you so much for this!

[@Trump_Gaming]

How'd it go? My exam is next week.

[@cranberryantipathy803]

i don't understand some answers on the link are not the same with on the video? 🤨

[@safesoundequine8511]

there are a couple of little mistakes in the video, for example in problem 11 the wrong heat of formation for water is recorded into the problem

[@kaansaroz8086]

you are much better than any harvard proffessor from my perspective

[@particleex6428]

At 43:38 I broke out in laughter when you said "if you can't solve this, I'm surprised you got to this level" 🤡

[@quon535]

i’m still confused
