Rewrite the following statement by adding the correct word.

Ammonia reacts with chlorine to give ammonium chloride and nitrogen.

Answer 1

Excess ammonia reacts with chlorine to give ammonium chloride and nitrogen.

Explanation:

Ammonia reacts in two ways:

1. If ammonia is in excess,

\[\ce{\underset{(Excess)}{NH3} + Cl2 -> \underset{chloride}{\underset{Ammonium}{NH4Cl}} + \underset{Nitrogen}{N2}}\]

2. If ammonia is in limited supply,

\[\ce{\underset{(Limited)}{NH3} + \underset{(Excess)}{Cl2} -> \underset{(Nitrogen trichloride)}{NCl3} + \underset{(Hydrogen chloride)}{HCl(g)}}\]
