### winter 2012 final 2a

for this problem why do we use the equation entropy=nRlnv2/v1
instead of using a 3/2R since it says constant temp.

### Re: pH and cell potential

like in the case of question 3 on the 2011 practice final i was wondering why the cell potential would increase if the pH increased since doesn't that make the pOH smaller and making the concentration of the OH smaller and making bigger Q and making it more -

### Re: 2012 Midterm Question 3A

I was confused on this question too but well since it is one mol for the O2 you get the same answer as 0 using the avogadros number when you calculate the W for the residual entropy equation.

### polarity question

When the lewis dot diagram has a set of lone pair and the bonds are all with the same atom is the molecule polar or non polar?

radical compounds will never have complete octets because they have unpaired electrons
it is usually with compounds that have an odd number of total valance electrons
