Hess's Law - Chemistry Tutorial

This chemistry tutorial covers how to solve for the enthalpy of reaction for an given reaction by using Hess's Law and the delta H values for other known chemical reactions. This tutorial involves several examples demonstrating the use of Hess's Law, which allows for the calculation of an unknown enthalpy of reaction from other reactions due to the fact that enthalpy is a state function.

Tries to teach you chemistry... steals your heart.

Perhaps the most seductive hess's law tutorial video I've ever seen

[jamesvongampai]

i love her voice. it makes chem really soothing to learn and less likely to give up :]

[silva]

you saved my life. thank you so much. and u have such sweet voice.god bless you.

[amalmohammad]

The whole Arab nation is watching your video hahahaha you've helped us in chemistry a lot !!! THANK YOU SO MUCH

[FireSymphoney]

YOU ARE AMAZING!! what the Chemistry teacher failed to teach in 2 hours you taught it in less the 15 Minutes, , Lady you deserve a Like And a Subscribe, ,Keep Up The BRILLIANT WORK!!

[satbirsekhon]

Honestly you make everything so simple to understand, probably the best video I've seen on Hess's law. Also I like how you showcase all your work. Thank you

[sbrodie]

This was extremely helpful for me - I used to think Hess's Law questions were about making up the enthalpy numbers for the moles of reactant but then I saw the way you cancelled out the moles in the equations and it was like an epiphany! Thanks Missy :-) xxx

WOW it's like I've crossed over to a new realm of understanding the LAW Thank

[SeunJubril]

Wow. 2 weeks of confusion cured in the first 3 minutes. Thank you. :)

I have a big test and this tutorial was AMAZING! I feel so much more confident now thanks!

[SoapyDuckling]

So I have an exam on this tomorrow and the entire unit I had no idea what my teacher was talking about when he said to flip the equation and multiply and now it makes perfect sense! Awesome video thank you!!!

[TheLonelyFawn]

Thank you!! Your method make so much more sense than the diagrams they draw at uni to try and explain it :L Really helpful!

How come at 8:25 she didn't just multiply the equation by 10 to make the 1/2O2 into 5O2? I thought you just had to look for similar compounds.

[HaloSpartan]

thank you so much for the help. hopefully i wont fail my test. also i have to be the billionth person to say this but you have a fantastic voice.

[logerbad]

Its guys like you the reason we dont get questions like these in the test a wrong answer, thank you so much

OH MY GOD.
THIS VIDEO SAVE ME in my last 3 hours of the online submission DEADLINE 

[MsForeverlover]

Thank you! Learned a lot from your video than I did from reading the chemistry book.

[GoOutAndBike]

I don't know what it is but I started to fall in love with chemistry all of the sudden <3

[jshatzman]

THANK YOU THANK YOU THANK  I was really struggling.  This doesn't mean I'll pass my midterm tomorrow but at least I can do the practice problems without crying now!
