Re: Benzene vs. Phenol
phenol is benzene with an -oh group attached to it, but I don't think we have to know phenol for the final.

Re: cis-trans
first compare the molar mass of the carbon molecules parallel to each other. If both of the highest priority are on the same side, it is cis, and if they are on opposite sides are trans.

Re: Bond Enthalpy w/ Diagram
bonds in reactants are broken and bonds in products are formed; count the different types of bonds in both the reactants and products, and if they show up on both sides then you don't have to account for them because they cancel out.

A small piece of ice which lived in a test tube fell in love with a Bunsen burner and said "Bunsen! My flame! I melt whenever I see you". The Bunsen burner replied :"It's just a phase you're going through".

Re: Reversible vs. irreversible processes
According to the second law of thermodynamics, any process that would reduce the entropy of an isolated system is impossible. If a reaction takes place in the forward direction and the entropy increases, then for the reverse process the entropy would decrease, which is impossible, so the forward rea...

Re: Homework 8.75
-270 kJ/mol refers to a single N-F bond, not NF[3] as a whole. Therefore, since there are 3 N-F bonds in NF[3] and there are 2 moles of NF[3] being formed, there would be 6 moles of N-F bonds.
