Question

Dry ${\mathrm{NH}}_3$ and $\mathrm{HCl}$ gases combine to form ${\mathrm{NH}}_4\mathrm{Cl}$.

• A. True
• B. False

Answer 1

The correct option is A True

1. When dry Ammonia (${\mathrm{NH}}_3$) reacts with Hydrogen chloride ( $\mathrm{HCl}$), solid Ammonium chloride is formed.
2. Reaction involved: $$\begin{gathered} {\mathrm{NH}}_3\left(\mathrm{g}\right)+\mathrm{HCl}\left(\mathrm{g}\right)\to {\mathrm{NH}}_4\mathrm{Cl}\left(\mathrm{s}\right) \\ \left(\mathrm{Ammonia}\right)(\mathrm{Hydrochloric}\mathrm{acid})(\mathrm{Ammonium}\mathrm{chloride}) \end{gathered}$$

Therefore, the given statement- Dry ${\mathrm{NH}}_3$ and $\mathrm{HCl}$ gases combine to form ${\mathrm{NH}}_4\mathrm{Cl}$ is true.
