Question

2NH3 + 3 cu O== 3 cu + N2 + 3 H2 O​

Answer 1

where is the question yaar

Answer 2

Answer:

N2 + 3 H2O

This is an acid-base reaction (neutralization): CuO is an acid, NH3 is a base.

This is an oxidation-reduction (redox) reaction:

3 CuII + 6 e- → 3 Cu0

(reduction)

2 N-III - 6 e- → 2 N0

(oxidation)

CuO is an oxidizing agent, NH3 is a reducing agent.
