If we want to find out some information regarding the enthalpy change of a reaction, but we don't want to perform the reaction, we can use Hess's law, which allows us to manipulate thermochemical data for related reactions. Let's practice this technique!

What's enthalpy? I don't understand ANY of this but I get a great sense of satisfaction knowing that someone out there does 👊😁👍

@saurabtharu7252 5 лет назад

Enthalpy is the sum of internal energy and pressure volume work done. It is equivalent to the total heat supplied to the system.

Hey Dave!! Love your channel. I am in ochem 2 and struggling with the Mannich reaction and was wondering if you were planning to post anything about it

@ProfessorDaveExplains 5 лет назад

i'll put it on the list!

@anden22127 5 лет назад

Omg I have an exam on this in a couple of days, thank you! Perfect timing!

It's been years since I've practiced any kind of engineering, and even longer since I've been in school, but this is still fun to listen to. (I'm also enjoying the Italian lessons) Thanks, Professor Dave! ❤️

Explanation was good👍👍👍 It's now clear to me

@bernhard5057 5 лет назад

Have a test on energetics tomorrow and this popped up in my feed

@jonasparan3169 4 года назад

Yes. A quiz at 9. Perfect

What if the given thermochemical equations have the same compound with what you're looking for, for example, for F2 then the given equations have F2, what equation to choose?

@crombuluted6577 3 года назад

I did not understand this lesson at all, until I found your video. Thank you so much for making this video Chemistry Jesus!! This is Lloyd, the green ninja, signing off

@sanasani700 2 года назад

So glad to see this video....Too much informative....your this short video has cleared my all concepts...

@weiv6229 3 года назад

what about when there are 2 compounds in one intermediate equation that both are unique to that one? Or also when none of the compounds in one intermediate equation are unique to that specific equation?
