Re: kJ or kJ/mol?
we measure both enthalpy and Gibbs free energy in kJ mol-1 (kilojoules per mole).

Re: Quiz 1 Answers
one of the TA's has a review session tomorrow in the CS76 lecture hall at 6pm, so you can go ask any questions about the quiz there.

Re: Units for Bond Enthalpy Questions
I think bond enthalpies are generally just expressed in units of kJ mol-1.

Re: Sig Figs
0.00021 has two significant figures: 2 and 1 (the zeros before the 2 are not significant).
trailing zeros in a number containing a decimal point are significant (ex: 32.2100 has six sig figs.: 3, 2, 2, 1, 0, and 0).

Re: Hess's Law
you should also know that when you reverse an equation, you have to reverse the sign on the enthalpy value too.
