Since oxygen is being added to the copper, the mass will increase by the amount of oxygen that bonds to the copper. `CuO(s) + H_2(g) -> Cu(s) + H2O(l)` In this reaction, copper (II) oxide reacts with hydrogen to generate copper metal and water. _____ 5) Copper (II) hydroxide decomposes to produce copper (II) oxide and water. Write and balance the equation for the combination of ammonia gas with solid copper (II) oxide to produce copper metal, nitrogen gas, and liquid water. Zinc + Sulphuric acid → Zinc sulphate + Hydrogen. copper i oxide balanced equation
