this guy speaks so clearly even auto-subs can understand his every word.

[sapio]

I love your voice, I listen to you to fall asleep. I used to watch your videos all the time in college, now I'm almost done with my masters in chemistry.

[montemorgan]

I swear this is the best tutor in the world❤️come to Kenya at The University of Nairobi and be our lecturer please😭I literally understand everything you teach in minutes despite spending hours stranded in the class understanding nothing😭😭God bless you alot❤️and if you’ve not subscribed to his channel, please do so coz he got some good stuff fr❤️🔥

[bluevelvet]

Thank you so much for the video! Seriously, this is from three years ago already but your lessons are still so useful! You're a life-saver!!

[cupcakeskyes]

I feel like I’m the only one here who is taking normal 10th grade chemistry... but this guys videos help me through so much.

[rob-tidw]

dude your videos are by far the most helpful on here. thank you.

Professor Organic Chemistry Tutor, thank you for an excellent explanation of Thermochemical Equations in AP/General Chemistry. Conversions continues to be an important tool in Modern Chemistry. Conversions is heavily used in examples/practice problems in this video. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.

I want to ask if the answer in last question is negative because 1 mol c3h8 is equivalent in - 2221 kj ? Thank you

[feyzaozudogru]

The only criticism I can make about the videos on this channel is that when I stop to solve the question on my own, the video title prevents me from seeing the first line of the question. If the questions start one or two lines below, I think we can stop and read the question over and over again and understand it easily.I don't see any problem other than that, thanks for your effort（人´∀`*）

Might sound a bit dumb but can you explain how did you get delta H from a reaction like that? Like what calculation do you have to do to get that kJ

[Imprettymuchamunch]

I'm not sure if this is correct. However I divided 2221kJ by 0.4 then used the exact same method you use but with
-5MJ and - 888.4kJ instead of 12.5MJ and 2221kJ.
Got same answer

[myrandadiaz]

literally every college student knows your channel

[gnatflatt]

Thanks man, this video helped me a lot!

[islamicbrotherhood]

Some more tough videos of thermochemistry needed

[johnkamil.devilla]

shouldn't it be -0.248 since the ∆H is equal to -2221kj??

[HayatAlrefaie]

i cant stand doing chemistry so this helped me out a ton

[waffleslmao]

How much energy is needed to make 300g of glucose

[AdacheMichel]

Sir why was the 40 percent stuff made to be 5 / 0.4 i could have sworn we would multiply rather than divide

[laasya]

here the H value is in kJ, but in the questions i was given, it is stated as delta H in kJ/mol. would i use the same methods from these practice questions?

[nadiraslam]

How do we do this when we're given 3 equations and we have to reverse some of the equations? Is there a video for that?
