Well it fully depends on what type of copper you have. if you have Cu1+ then when you do an ionic equation and switch the ion charges, then the compound you would get would be Cu2O. If you had Cu2+ then the compound would end up being CuO. You cant just put two things together and assume its right. You have to do an ionic equation and then balance your reaction.

H2 + O2 --> H2O is incorrect because it is not balanced, i.e. it does not have the same numbers of atoms of each element on both sides. Coefficients must be added in order to balance the equation. The correct balanced equation is 2H2 + O2 --> 2H2O.
