Blister copper is formed by the reaction Cu2S+O2(g)→Cu(l)+SO2(g)\text{Cu}_2\text{S}+\text{O}_2(g)\rightarrow\text{Cu}(l)+\text{SO}_2(g) In the reaction, (a) O2\text{O}_2 oxidises S of Cu2S\text{Cu}_2\text{S} to SO2\text{SO}_2 and Cu+\text{Cu}^+ of Cu2S\text{Cu}_2\text{S} to Cu\text{Cu} (b) O2\text{O}_2 oxidises S of Cu2S\text{Cu}_2\text{S} to SO2\text{SO}_2 and reduces Cu+\text{Cu}^+ of Cu2S\text{Cu}_2\text{S} to Cu\text{Cu} (c) Cu2S\text{Cu}_2\text{S} first changes to Cu2O\text{Cu}_2\text{O} by O2\text{O}_2, and then Cu2S\text{Cu}_2\text{S} changes to Cu\text{Cu} and SO2\text{SO}_2 (d) All the above are correct statements
