Re: Organic Chemistry Textbook [ENDORSED]
Have you posted more questions suggested for us to do out of the organic textbook? I haven't found any following Quiz 3 and I can't remember if you said anything about it in lecture or not. Thanks!

Re: 1.16
I originally had 1-Isopropyl as well because I thought with two substituents, they needed to be placed in alphabetical order and with the lowest number first as well, and I was wondering as well if this is by choice or why 2-Isopropyl is solely the correct answer?

Re: Cell Diagrams
I'm confused on how the value of that works, not necessarily the writing of the cell diagram itself, but when you're allowed to have a negative Ecell value or not. I was told i just had to choose the cathode and anode based on whichever order I'd get a positive value, but on the hw and in the practi...

Homework 14.1
For Part A, it asks which elements are undergoing changes in oxidation, but the solutions manual lists Cr as undergoing reduction and the Carbon being Oxidized. Part B asks to balance the oxidation half reaction, and the carbon is used for this, so is the Cr listed just an error for this problem?

Re: Quiz 1 Preparation Answers
5kJ of energy is the internal energy itself, not the change in internal energy. The question wants to know how much the internal energy CHANGE is. Just because the starting internal energy is 5 doesn't mean anything in an isolated system, because there is no change, so the change of internal energy ...

Homework 8.59
For 8.59, it says to calculate standard reaction enthalpy, so when I am trying to products - reactants, why does the solution manual leave out 7mols of N2? In the notes, it includes everything, regardless of state of matter?
