Question

Give chemical equation(s) to prove that NH3 contains
nitrogen and hydrogen ?​

Answer 1

Answer:

2NH3 gives on rxn N2 and 3H2

Answer 2

This reaction is reversible and exothermic. From the reaction, it is proved that ammonia contains nitrogen and hydrogen.

\[\ce{4NH3 + 3O2 ->[HEAT]2N2_{(g)} ↑ + 6H2O_{(g)}↑}\]

Also,

Ammonia burns with a yellowish flame. It produces water vapour and nitrogen. This shows that ammonia contains nitrogen and hydrogen.

\[\ce{N2 + 3H2 <-->[Fe/Mo][450-500°C]2NH3 + Heat_.}\]
