Cu2S + O2 → 2Cu + SO2. Let's look at the oxidation states of everything. In the copper (I) sulfide, the copper is +1 and the sulfur -2. The oxidation states of the elements oxygen (in the gas) and copper (in the metal) are 0. In sulfur dioxide, the oxygen has an oxidation state of -2 and the sulfur +4.
