I have a couple of chemistry questions I can't figure out.
1. Which element is oxidized in the following reaction: CuO(s) + H2 (g) Cu(s) + H2O (l)
2. If 5.40 kcal of heat is added to 1.00 kg of water at 100⁰C, how much steam at 100⁰C is produced? Show all calculations leading to an answer.

Oxidation is:
1.addition of oxygen
2.removal of hydrogen
3.addition of electronegative electrons
4.removal of electropositive electrons
so see which element has undergone any of the above 4 changes
