Question

The statement given below is incorrect. Write the correct statement.

Ammonia gas and $\mathrm{HCl}$gas react to form gaseous ammonium chloride.

Answer 1

Combination reaction: It is the type of reaction in which two or more reactant molecules combines to form a product.

• Ammonia gas (${\mathrm{NH}}_3$) upon reaction with hydrochloric gas ($\mathrm{HCl}$) results in the formation of Ammonium chloride(${\mathrm{NH}}_4\mathrm{Cl}$) in a solid form, not in a gaseous form.
• It is a type of combination reaction.
• $\underset{\mathrm{Ammonia}}{{\mathrm{NH}}_3\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrogen}\mathrm{Chloride}}{\mathrm{HCl}\left(\mathrm{g}\right)}\rightleftharpoons \underset{\mathrm{Ammonium}\mathrm{Chloride}}{{\mathrm{NH}}_4\mathrm{Cl}\left(\mathrm{s}\right)}$

Correct statement: Ammonia gas and $\mathrm{HCl}$ gas react to form solid ammonium chloride.
