Answer 2

Answer:

A pungent odour gas is ammonia.

Explanation:

Ammonia is a colourless gas and has a pungent smell. It is a compound of nitrogen and hydrogen. Its chemical formula is $NH_{3}$. It is lighter than air and is easily liquifiable. It is formed by the combination of nitrogen and hydrogen.

$N_{2} + 3H_{2}$ → $2NH_{3}$

Ammonia is corrosive and exposure to high concentrations of ammonia in air can result in blindness, lung damage, or death.  Inhalation of even lower concentrations of ammonia gas can cause coughing, and nose and throat irritation.
