Explanation:
3CuO+2NH

⟶N
2
+3H
2
O+3Cu
Oxidation state of N in NH
3
=−3
Oxidation state of N in N
2
=0
The change in oxidation state of N is loss of 3 electrons.
There are two atoms of nitrogen, hence the change involves loss of 6e
−
for 1 mol of N

.
3CuO+2NH3⟶N2+3H2O+3Cu
Oxidation state of N in NH3=−3
Oxidation state of N in N2=0
The change in oxidation state of N is loss of 3 electrons.
There are two atoms of nitrogen, hence the change involves loss of 6e− for 1 mol of N2.
