We will cover how to find the change in gibbs free energy, enthalpy and the entropy of the system and the universe. We also go over an advanced thermochemistry question, how to find the identity of an unknown compound when given percent composition by mass of each element and how to draw bohr's atomic model with isotopes.

🙌 This was my go-to homework help when I was in school. Chegg Study is one of my favorites.

📚 I made the mistake of buying all of my textbooks, I wish I had the option of renting them. Thankfully you do, with Chegg Textbook Rentals.

💁‍♀️ HI I'M MELISSA MARIBEL
I help students pass Chemistry and Organic Chemistry. I used to struggle with this subject, so when I finally graduated with a bachelor's degree in Chemistry, I became a tutor so that you wouldn't have to struggle like I did. I know that with the right help, YOU CAN LEARN ANYTHING!

I wish I would have found your videos earlier than 30 minutes before my exam! You explain things so much easier than my professor ever did!!!

I love your videos, so sad I discovered them so late. But I still got 4 more days until my final, so I'll keep watching as much as I can! Great work!

On my calculator for the advanced thermochemistry problem I did not get -7.32•10^7 instead I got -1.65•10^6. How did you get your answer?

That's because she accidently divided the two numbers. However, you are supposed to mutilply so you were correct.

at you 16:17 I know the question asked for change in S of the surroundings but I was wondering if we should always use change in S of the surroundings when looking at the chart. Or does it depend on the question?

If a spontaneous process is endothermic, that would mean delta H needs to be positive. That said, how would that affect the entropy of the surroundings? Decreasing?
@scienceislove2014

All spontaneous processes are not exothermic, because it is the Gibbs Free energy that determines spontaneity, not the enthalpy.
