Rapid interconversion of the chair

When is interconverting the chair (cyclohexane) necessary/ is it something we should be familiar with doing?

q=mCT vs q=cT

How do you know which one to use?/what is the difference? For example, in winter 2015 final 1B you use q=mCT but in 1D you use q=cT.

Winter 2013 Q3B

In this problem you are asked to calculate Ecell, so you use Ecell = Ecathode - Eanode. E of the anode is given as -1.33V, so I don't understand why you make it positive, and then subtract it from the Ecathode. Can someone explain?

Re: Practice test #3 2014

I have a question about this problem too! Can someone explain how you can tell which chemicals would produce the highest voltage possible? (part A)

How to tell if you're dealing with an ideal gas?

In the winter 2014 final, question 2b, you're asked to calculate the final pressure of a sealed container of gases. The equation used is PV=nRT, but the problem does not specify that the gases (Argon and Neon) behave as ideal gases. How would you know that they do in order to use the ideal gas law?
