Cuprous oxide (Cu 2 O), cupric oxide (CuO) and cuprous sulfide (Cu 2 S) are produced as powders by the controlled reaction of oxygen with copper powder. The products are used in antifouling paints (Cu 2 O), reagents in chemical reactions, catalysts in the production of silicone compounds and in foundries for hydrogen degassing of non-ferrous melts.
Step 4: Substitute Coefficients and Verify Result. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Since there is an equal number of each element in the reactants and products of 2Cu + O2 = 2CuO, the equation is balanced.

Both forms of copper oxide are used to produce pigments. The "I" and "II" in copper oxide represents the number of electrons that the metal has provided when copper oxide is brought into contact with metal. Some uses for copper oxide are: Building copper-based structures. These structures gradually change color due to oxidation.
