Chemistry Help

I not sure if i put this thread in the right place, but whateva.

Well if any one has learned stoichiometry, i need someone to help me balance this equations:

1. Cu(NO3)2 + NaOH --- CuOH2 + NaNO3




2. Cu0 + H20 --- CuOH2


3. HCl3 + Cu2O3 --- CuCl3 + H2O

let me see..
1.Cu(NO3)2 + NaOH --- CuOH2 + NaNO3
Cu(NO3)2 + 2NaOH --- CuOH2 + 2NaNO3
I'm not sure but I think that's for number 1.

2.CuO + H20 --- CuOH2
2CuO + 2H2O---2CuOH2
wait... I'm getting confused.. Well, anyways I'm just trying to answer. Can you tell me if it's correct next time?
