Question

Cupric oxide will be converted to metallic copper when it is heated with hydrogen.

• A. True
• B. False

Answer 1

The correct option is A

True

Cupric oxide will be converted to metallic copper when it is heated with hydrogen.

$CuO+H_2\to Cu+H_{2}O$

This reaction is a typical redox reaction (oxidation-reduction). Hydrogen reduces the oxide of the less reactive metal to free metal.
