Question

What happens when (give balanced chemical equation also) :

Ammonia is passed over hot copper oxide?

Answer 1

1. When ammonia gas(${\mathrm{NH}}_3$) is passed over the hot copper oxide($\mathrm{CuO}$) it is oxidized to nitrogen(${\mathrm{N}}_2$) and water(${\mathrm{H}}_2\mathrm{O}$).
2. The reaction for the same is-
3. $3\mathrm{CuO}+2{\mathrm{NH}}_3\to 3\mathrm{Cu}+{\mathrm{N}}_2+3{\mathrm{H}}_2\mathrm{O}$
