उत्तर
Ammonia is collected by downward displacement of air in an inverted gas jar.
Explanation:
Ammonia gas is lighter (less dense) than air, causing it to rise to the top of the inverted jar and push the heavier air downward. Additionally, it cannot be collected over water because it is highly soluble in water, meaning it would dissolve instantly rather than filling the jar.
