Cycloalkenes and Geometric Isomers
How do we know when to use cis or trans with cycloalkenes? For example, on the 2012 final, question 5A, molecule B is a geometric isomer. However, on the 2013 final, question 6A, why isn't the molecule a geometric isomer?

Re: Getting the rate law from the integrated rate law
Consider a general reaction of nth order in reactant A: A->Products. Its integrated rate law is 1/([A]^(n-1))=(n-1)kt+1/[Ao]^(n-1). Based on the Integrated rate law, what is the rate law for this reaction?

Amount of Heat required to heat up gases
For question 1B on the 2010 final exam, could someone explain why it takes more heat to heat up 1 mole of butane gas than it does to heat up 1 mole of h2 gas from 10 to 20 degrees celsius? Also could someone explain the second part of question 1B?

Drawing Lewis Structures
When we are asked to draw Lewis Structures where the central atom can have an expanded octet (like P, Cl, S, etc), should we draw the Lewis Structure where the formal charge on the central atom is zero?
