Energy vs. Dihedral angle graph

When making this graph about a newman projection, do you start at a certain point as 0 degrees? do you have to start at eclipsed or staggered? My question is where do I start when Im drawing this graph, what angle and how?

Nerst Equation?

On the formula sheet I know there is the shortcut to the nerst equation where in the nurmerator there is 0.05916V. I was wondering how do oyu get that from the actual equation? I keep getting a different number.

Review

Is there a page/facebook or forum where the TAs post their review sheets to help study? I was searching for Idean's from last night and I cannot seem to find it. If there's a general page with even more that would be very helpful.

Re: Naming for multiple cycloalkanes

If they are equal size and same length from each other then it does not Matter which one you name first. Just stay consistent

Anode and cathode

When I am given two half reaction and the electrons are both on the left side (because E is given that way) and both values of E are given. How do I tel l which one is the anode and cathode?

Midterm 2011 question 1

In the winter 2011 midterm question one says: The enthalpy of combustion of benzoic acid, C 6 H 5 COOH, which is often used to calibrate calorimeters, is -327 kj x mol -1 . When 1.453 g of benzoic acid was burned in a calorimeter, the temperature increased by 2.265 degrees C. What is the heat capaci...

Calculating values in nerst

How do you find what the value of n in the denominator is? Also how do you find out the concentrations for the value of Q?

Deriving equations

In lecture, Lavelle put a huge emphasis on deriving the different equations in this section dealing with reversible and irreversible expansion. Everytime it seemed like the steps were scattered and hard to follow, so can someone please explain the steps or post a link where it explains the deriving?

Homework

In my discussion (with TA Dimitri) we began talking about reversible and irreversible reactions and then in lecture it seems we have not gotten there yet. I was going to fill this gap with reading the book but it seems like we started in the middle of the chapter. What sections or parts of chapter 8...

Octet Rule

Is there a pattern or way to know which elements have exceptions to the octet rule or is it just best to memorize them? Also what are the different types of exceptions? (ex. Expanded etc.)

When quizzed/tested on electronic configuration, are you allowed to use the shorthanded version? For instance the brackets with the element from the previous period.
