Copper(II) oxide is CuO. When binary compounds (compounds composed of only two elements) decompose, they produce their elements. So the unbalanced equation would be: CuO(s) --> Cu(s) + O2(g) Now you have 1 Cu and 1 O on the reactant side and 1 Cu and 2 O on the product side. To balance, first put a coefficient of 2 in front of CuO so each side has 2 O. 2CuO(s) --> Cu(s) + O2(g) This leaves 2 Cu on the reactant side, but only 1 Cu on the product side so now put a coefficient of 2 in front of Cu so each side has 2 Cu. 2CuO(s) --> 2Cu(s) + O2(g) The equation is balanced!

Metallic copper reacts with an excess of oxygen to form copper(II) oxide or with a deficiency of oxygen to form copper(I) oxide.
