Question

What are the products formed when ammonia is oxidized with copper oxide?

• A. Copper nitride and water
• B. Copper nitride and water
• C. Copper, water and nitrogen dioxide
• D. Copper, water and nitrogen

Answer 1

The correct option is D

Copper, water and nitrogen

When ammonia is oxidized with copper oxide, the products will be copper, nitrogen and water vapour.

$3CuO+2N{H}_3\to 3Cu+N_2+3H_{2}O$

Ammonia reduces cupric oxide to the free metal and itself gets oxidized to nitrogen.
