How do you know when to use the prefix "neo"? Is it always when there is a tert-butyl?

Re: how to calculate n correctly

You can also balance the reactions by using the oxidation and reduction half reactions. Find the number of electrons that are cancelled out and that will be n.

Q8.23 in textbook

For question 23 in Chapter 8 in the textbook, when calculating the heat capacity of the calorimeter, you use q=mc(delta)t. The solution to this problem is 22.5kJ/(23.97C-22.45C) = 14.8kJ/C. Why is mass not seen in this solution? Is it assumed the calorimeter's mass is 1g?

Work = 0 in a calorimeter/isolated system? [ENDORSED]

During lecture it was said that if Vol (reactants) = Vol (products) then deltaH = deltaU. This is because deltaU = qp + W, but W is equal to 0 so deltaU=deltaH. Why is work (W) equal to 0?
