Question

C + H+ CuO → CO₂ + H₂O + Cu balance this ​

Answer 1

Explanation:

CuO+NH

3

→Cu+N

2

+H

O

Balance all atoms other than H and O.

CuO+2NH

O

The oxidation number of Cu changes from 2 to 0. The change in the oxidation number of Cu is 2.

The oxidation number of N changes from -3 to 0. The change in the oxidation number of one atom of N is 3. For 2 N atoms, the total change is 6.

The increase in the oxidation number is balanced with decrease in the oxidation number by multiplying CuO and Cu with
