Practice Problem: Hess's Law

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]

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

[@arham6356]

The total heat content of a body

Chemjesus, you are the only one who got the power to clear the concept within 4 min video! ✨ Thank you 😊🙏

[@daniellezepess]

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! ❤️

[@anden22127]

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

[@adlksgffklagj]

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

[@kumarchetri465]

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

[@lilyanderson8115]

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]

i'll put it on the list!

[@sanasani700]

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

[@jonasparan3169]

Yes. A quiz at 9. Perfect

[@divyanshigupta2348]

Thanks sir

[@hoodoo457]

Needed this

[@saurabtharu7252]

Thanks Professor
For right video at right time😊😉

[@parasuramang1860]

Thank you so much for your videos. I would like to get some references books names that you use for Chemistry..

[@i_Kashifmir]

Thanku so much sir🫡beautyy explanation❤

[@crombuluted6577]

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

[@justinwoessner679]

this helped me so much your a life saverrr

[@cahjsingh6491]

excellent explanation!

[@RealEverythingComputers]

Thanks great explanation!

[@aayatkhan8498]

Love you sir

[@weiv6229]

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?

[@harihar5279]

So much thanks Dave 🔥

[@prakashdasa6913]

Thank you so much sir

[@bagsik9251]

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?

[@YeAhEa_18]

Yaay ! Did it allright..:)

[@shweathak7833]

Superb
