Upon heating with `Cu_(2)S` the reaction (s) that give copper metal is /are

A

`CuSO_(4)`

B

CuO

C

`Cu_(2)O`

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
D
`CuFeS_(2) + Cu_(2)S overset(Delta)rarr` No reaction
(b) `2CuO overset(Delta) rarr Cu_(2)O + 1//2O_(2)`
(c ) `2Cu_(2)O + Cu_(2)S overset(Delta)rarr 6Cu + SO_(2)`
(d) `CuSO_(4) overset(Delta)rarr CuO + SO_(2) +1//2O_(2)`
Both CuO and `CuSO_(4)` upon heating produces call CuO respectively and further `Cu_(2)O` and CuO on with `Cu_(2)S` gives Cu.
