Question
Upon heating with Cu2S, the reagent(s) that give copper metal is/are
Options
A.CuFeS2
B.CuO
C.Cu2O
D.CuSO4
Solution
Cu2S + 2Cu2O 
6Cu + SO2
Since, CuSO4 as well as CuO both on heating produces Cu2O as shown below so, they also produce Cu on heating with Cu2S.
2CuO Cu2O + 
O2
CuSO4 CuO + SO2 + O2
6Cu + SO2Since, CuSO4 as well as CuO both on heating produces Cu2O as shown below so, they also produce Cu on heating with Cu2S.
2CuO
Cu2O + O2CuSO4
