B

`CuO`

C

`Cu_2 O`

D

`CuSO_4`

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
`CuFeS_2 + Cu_2 S overset(Delta)to ` No reaction
`2CuO overset(Delta)to Cu_2 O + 1/2 O_2 `
`Cu_2 SO_4 overset(Delta)to CuO + SO_2 + 1/2 O_2`
Both `Cu_2 O` and CuO on heating with `Cu_2 S` give Cu.
