### Re: Oxidation vs. reduction

If the little plus sign gets higher, it means the atom is losing an electron and therefore is being oxidized.

Constant volume and constant pressure are two different situations for a gas. Therefore, there must be two different values for molar heat capacity of gas.

### Re: Why can state properties be added?

Due to the fact that they are not based on the state of the substance, they are not an intrinsic property. Therefore, they can be added and substracted.
