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 KZfaq TV with the Organic Chemistry Tutor.

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

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´∀`*）

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?

@uuitgaurav 2 жыл бұрын

Just multiply the moles used in reaction to get whole energy used in reaction.

why was 2221KJ positive when dividimg to find how many Kg we need to produce 5Mj

@waynerelampagos4285 3 жыл бұрын

The 12.5 MJ is also negative. So when the -12.5 KJ will be divided - 2221 KJ, the answer will be positive
