Solution

Nitrogen gas is evolved:
Following observations are made:
1. When ammonia gas is burnt in the atmosphere of oxygen, it forms Nitrogen gas and water vapors.
2. Green-colored gas is observed due to the formation of Nitrogen gas.
3. The chemical transformation seen in this case is
$4 N H_{3} (g) + 3 O_{2} (g) \to 2 N_{2} (g) + 6 H_{2} O (l)$
Ammonia Oxygen Nitrogen Water
Gas gas gas
Final Answer:
Nitrogen gas is evolved.
