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?

Galvanic Cells
How do you do 14.46
The standard potential of the reduction of Ag2CrO4 to Ag and chromate ions is +0.446V. Write the balanced half-reaction for the reduction of silver chromate. Using the data from part a and Appendix 2B, calculate the solubility product of Ag2CrO4

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...
