When to use enthalpy values?

For #7 on quiz 1, the answers posted says to use deltaH(vap), but we're talking about condensation, so why do we use vaporization?

Help on Homework Problem

I need help with 14.30: Suppose that each of the following pairs of redox couples is joined to form a galvanic cell that generates a current under standard conditions. Identify the oxidizing agent and the reducing agent, write a cell diagram, and calculate the standard cell potential. a)Pt2+/Pt and ...

HW 8.51

The question asks "The enthalpy of formation of TNT is -67 kj/mol and the density of TNT is 1.65 g/cm. In principle, it could be used as a rocket fuel, with the gases resulting from its decomposition streaming out of the rocket to give the required thrust. In practice, of course, it would be ex...
