Re: Chair conformation
Does it also not matter where we start counting the carbons? My answers are almost always slightly different than the book.

Re: Post All Chemistry Jokes Here
I told a bad joke about Helium one day, but nobody was reactive.

Re: Slow step vs. Fast step
It depends on the mechanism given. The slow step is always the rate determining step. Therefore, all steps after that we can ignore. Since the slow step is an elementary reaction, you can determine the rate law from the stoichiometric chemical equation. If the mechanism is given as a slow then fast ...

Re: Derivations
Anything covered in lecture is all fair game. I'd focus more on Ch 8/9 equations though.

Re: PRACTICE QUIZ 1 (#9)
Adding on, The Second Law of Thermodynamics states that the state of entropy of the entire universe as an isolated system will always increase over time! While we can know that delta G is 0 because it's a state function and we have identical initial/final states inside our system, the delta S of the...

Re: Quiz 1 Preparation: Question 6
Yes, since it releases heat it must be exothermic so the sign is negative.

Re: Course Reader clarification [ENDORSED]
I agree, it would probably be fairly simple. For work, I think it would be similar to the basic integrals we did in LS30A during the beginning of Riemann Sum lectures. (In another thread Dr. Lavelle replied that all derivations in lecture are technically "fair game" but derivations aren't ...

Re: Bond Enthalpies
Both ways can work, though breaking and forming every single bond would be a bit time consuming (I think Dr. Lavelle said this in Weds lecture during an example). To figure out which ones are broken and which ones form though, he drew the structures of the molecules (both reactants and products) and...
