Solution

Burning of ammonia gas $({NH}_{3})$ in oxygen:
Ammonia is neither combustible nor conducive to burning. Although ammonia does not burn in air, it does so in an oxygen-rich environment with a green flame. Ammonia and oxygen are delivered via thin tubes.
Ammonia burns with a greenish flame when lit with a torch. During the combustion of ammonia, free nitrogen and water vapor are produced.
The reaction is as follows:
$4 {NH}_{3} (g) + 3 O_{2} (g) ⟶ 2 N_{2} (g) ↑ + 6 H_{2} O (vapors) + Heat$
Therefore, a sample of nitrogen be obtained from ammonia by heating ammonia in oxygen rich environment. The reaction involved is:
$4 {NH}_{3} (g) + 3 O_{2} (g) ⟶ 2 N_{2} (g) ↑ + 6 H_{2} O (l) + Heat$
