i have learned more chemistry from this channel than my chemistry teacher
watch his ads bro or donate him this guy is legend
Funny then, that during the school shutdown, my chem teacher is making us watch this.
@@aidang7278 😂😂
Me too
me too this channel is very wonderful i love it
I hate chemistry with every fiber of my being
I did not understand hess's law problems until 20 min ago. Thank you.

I don't know how students before the year 2016 used to survive varsity life without this guy around, but all I know is that i learned more from this channel in class.
It's mind boggling how some great people can make chemistry so simple and straightforward. And meanwhile we have these ginormous textbooks and professors that use all kinds of symbols, texts calculations and more symbols from like Area 51 to explain 1st year chemistry. You can tell right away who're the good teachers and who're the bad ones.
I’m here because the past 2 weeks my physics “teacher” has literally just written equation after equation with 0 explanation or conceptual examples. 5 minutes of this video on 2x and I’m ready for the test today lol
Mine is definitely bad
I never been so happy
You deserve to be on every students TH-cam feed
I so much agree ✨
It's trippy how easy Chem is when you actually understand the material. Thanks for the help broski, keep up the good work
I have a chemistry exam this Tuesday on Thermochemistry including a problem on Hess' Law. Your tutorial is exactly what I needed in order to successfully solve the practice exam problems. Thanks so much!
LOL same here dude but a year later
how did your exam go? do you remember your score
@@ibtisamatiq9575 Same here, but another year later
@@hadieartiel1147 haha good luck
have one in about 12 hours lol
The organic chemistry tutor, you are the hope of all high school and college students. Thank you
Would just like to say thank you. I was gone this day, and since this is review, our AP chem teacher is going over our thermochem unit in like 3 days. Not just this video, but your channel is a lifesaver, and I feel so confident for my test tomorrow. Thank you so much for saving my GPA and letting me love chem!!!!!
I had given up on understanding Hess's Law until i watched this video. Thank you so much! You don't know how much you've helped me and many other students
Veteran finally back in school, you're saving my life man. Cant thank you enough.
This tutorial has been very helpful in my adventure in thermodynamics and especially Hess law problems. Thank you. Please continue such a good work. You are a light for many student a cross the globe.
dude with this Quarintine going on my classes are online so I cannot see the tutors. I have heard this 1000000 times but when you say it, i get it. Thank you so much !!!!!!!
the best explainer ever.
u got 69 likes. Be proud !!
@@adlindkodra9910 not anymore lmao
I am in general chemistry with the lecture online and the lab on site. It has been tough because the methods my teacher uses leaves me seeking other sources (such as this one) to effectively learn chemistry. It has been time consuming and difficult with the text book being so wordy and not giving the work outs for the math involved. I have found tutoring and this channel to be the absolute most helpful ways to learn. I am so grateful that these videos are here to watch and replay to learn! Thank you so much!
I will forever be thankful to this man, bro u teached me 11th and 12th grade physics and still helping me now that I’m in college
I actually have so much love for you. you make chemistry seem so much easier than what the teachers/textbooks show it to be
THANK YOU! I was totally spacing when my chemistry professor was going over this and this helped so much. I didnt realize it was so simple.
And suddenly this became the easiest thing. Thank you so much!
These videos are sent from heaven. I’m a 34 year old premed nurse taking intercession chem and I literally can’t keep up. I watch these videos after school every day
Hi, i just learned more in this 20 mins video than i ever did in those daily 1hr lectures. THANK YOU!
wow sir.. i FINALLY understood this topic. Loved the way you explained everything so easily. It was fun learning ! Thank you so much 😊
Thank you so much! You teach so much better than my instructor! I paused the video and did the problems, and I actually got the right answers!
simple, to the point and beautifully explained .THANK YOU
Hi,I don't know if you will read my comment but thanks to you I've managed to survive and pass Chemistry. You go at a good pace and are very thorough, thank you so much. I've been subscribed for almost a year now too :)
You explaining the rules and having the a+b+c examples really helped a lot, you just goated on another level.
You made it so easy for me to finally understand it! Thank you!
Very concise and easily understandable explanation of Hess' Law. Thank you.
Thank you so much! You make an already hard class easier because you explain everything so well!
This was such a good video! I completely understand the concept now! THANK YOU SO MUCH!!!!!
ive never understood this concept until this video, thank you so much you are the reason why I am able to ace chemistry!!
Thank you so much for your explanations. You're the best. May God bless you
You are an excellent teacher! Students are lucky to have access to your lessons! Thank you
Thanks for breaking it down so well, especially with the letters in the beginning.
Actually , the tutorial is amazing ans clear! I learned this in my chemistry lectures, but it was not clear for me. you have explained it well. Iam so happy to say it .
very clear explanations on the Hess's law, this is exactly what i wanted. you are awesome
The great description really helped me out! God Bless!
I had no clue how to do this. Appreciate the conciseness!
My chemistry teacher doesn't explain this stuff very well so this video has made the entire class understand it that much more.
Thank you for the powerful knowledge sir. Each time I watch your videos I learn something new.
No teacher could every teach me that this guy did that too in a very very easy way! Thanks ❤️
I LOVE YOU THANKS FOR MAKING THIS 1000x MORE SIMPLE THAN HOW MY TEAcher EXPLAINS IT
I'm so grateful for your videos ... words can't even describe it.
I have my final CHEM 101 test tomorrow and this was the last concept I still couldn’t grasp. Thank you for making this video, it really is great that this channel has videos on whatever I need to learn.
if you are watching these videos the day before the exam, it wont go well
you are really helped me through g10 and 11 i never understood chemistry from my teachers but i did understand from you. thank you
Thank you very much. You helped me a lot and you are a great explainer. I have a test on this tomorrow ,and it really helped.
Thank you! I understood this section of Hess law. Followed along with the practice and understood. There are some other problems in my topic that are with moles instead so I will probably have to do this another way. But I really appreciated it as I started from knowing nothing 😊
Dude, your voice sounds so much like a Creepypasta voiceover channel I expected something scary to happen. Instead, this video was absolutely terrifying. Chilling. Haunting. Keep up the good work.
This has been extremely helpful in consolidating what I have learned.
You saved my life and I want to give you my thanks. I wish I found your channel before I took my midterm but acing my final will have to do
Never stop doing this, you are the man!
Professor Organic Chemistry Tutor, thank you for a basic explanation of Hess Law and How to apply it to Enthalpy Change of reaction by finding the heat of summation of individual reactions in AP/General Chemistry. Although the practice problems are simple to follow and understand, I am still confused about this material. I will review Hess Law from top to bottom in order to understand this material. This is an error free video/lecture on TH-cam TV with the Organic Chemistry Tutor.
Thank you for stating multiple examples..which have made me understand Hess' Law much better..
Good
Thank you very much! You video really helps. I’m dealing with worse chemistry teacher. This really clarified the concept.
Really thank you too much ... your way of explanation is too perfect👌❤
ever since i watched ur phy's vid i keep on watching your vid for every topic tht we learn in college.. tq so much ❤️
Learning from this channel was so much easier than using snap revise.. i understood better and no more confusion
You are literally so amazing! Thank you so much for making these videos!!
Love you. It's very helpful for clearing concept for jee
Im in chemistry AP (advance program) and i question myself everyday why i took ap. bu thank you for this video no I understand more about hess law. GOOD LUCH LUCK FOR MY CHAPTER EXAM
Sir much respect to you. You’ve made things soo easy for us.
Thank you so much! This helped a lot. I will share your video with my classmates. :)
Your videos are such a great help, thank you!
Thank you so much. This really help me for my chemistry quiz right this afternoon!
i missed part of my zoom meeting because of bad wifi and you helped me get back on track! tysm!!
Woooww I'm able to do all my exercises. Thank you so much.
thank you for blessing this earth with ur presence
I have thermochemistry exams tomorrow so this is reallyyy a great help. I'm still in my first year computer engineering course and I feel overwhelmed, especially in chem, so this channel really helped me a lot. I hope 4 years from now, I've graduated from this course tho🤣
i have a thermo test on tuesday and this really helped thank you :)
I not understand anything when I learn this in class but now I understand everything from this video 😍 thank you so muchh, you are the best teacher ever 👍
Thank you so much sir. I was finding it difficult to understand this but with your video I knw clearly understood
wow i just learned my whole unit from your videos! night before the test :> thanks
You are a saviour man, amazing explanation sir
watched 2 full ads because this man deserves it. Youre amazing!!
I would have but each ad has 2 parts and the second one was 18 mins lol
Thank you for explaining it well and makes it so easy to understand
if you're more math oriented/have taken precalc, take a close look at this (and balancing equations, and redox, and so much other shit)...it's all linear algebra/matrix algebra/systems of linear equations. If you're good with matrices or want a more rigorous way to go about solving these, you can balance anything like this using matrices, row reduction, and finding the determinant.
(figured that one out on my final by complete accident when I decided "fuck it". It worked.)
Omg ty
going to try using matrices on the problem from 7:34
actually how would you use the values from 7:34 and out that Into a matriz
only 15 min of this video made me comprehend the law problems.. I can create my own questions on it..
Thanks so much for helping us all out with this! You are awesome :)
I have finals tomorrow for this complicated topic...
Pray for my survival🙏
Edit:slr I survive hahaha hooray! This is really helpful!✨ thanks✨
Shera Haya Kichin how did it go lol
Want dat Cadpat ur about 6 and a half months late.
@@wantdatcadpat44 Didn't survive
Yo how did it go??
how did it go?
thanks man. im having a hard time with my thermochemistry. going to help a lot
Thank you so muchhhh! I'm having problem with my modules for about 1 hour as it didn't even explain or show how the heck can we solvce the question. But glad that I watched this
The day u started ur TH-cam channel is sincerely the best day for me😊
He is one of the best human being to exist. May God bless him!
YOU EXPLAINED IT PERFECTLY THANK YOU
I have a quiz tomorrow about this and I had no idea how to do this until i saw this video so thank you so much!
Such a good video Helped me out big time!!! Thanks
Your teachings are very easy to get the concept good job👍
Thank u sooo much
Really helped me out, concept got crystal clear within a limited time🥰
Thanks you so much. You have taught me so much chemistry. My chemistry teacher was absolutely uselsss. I'm definitely going to pay it forward somehow to someone else😭
I took extra paid classes to understadn thermodynamics.. I was not even able to understand the hess's law problems.. after only 15 min of this video.. i feel like i can create my own questions upon hess's law... You are a master.
Bro Thanks For The Explanation It Was Easy To Understand.
I hv improved drastically in my chemistry and physics thanks to you ...now my colleagues Wer lyk hey wats ur secret and I was Lyk
ORGANIC CHEMISTRY TUTOR😂😂 Thanks men🙏
The concept is more clear. Thankzzz a lot
