(d)

To determine

To classify: the given reactions.

Explanation of Solution

Introduction:

The chemical reaction is a process in which the materials are converted to one or more separate compounds, the reactants. The substances are either compounds or chemical elements.

In the following reaction, Cl and NO₃ are displaced from Na to Ag. The given reaction is,

  $\text{NaCl}\left(\text{s}\right){\text{+AgNO}}_{\text{3}}\left(\text{aq}\right)\to {\text{NaNO}}_{\text{3}}\text{+AgCl}\left(\text{s}\right)$

Thus, the given reaction is a double displacement reaction.

Conclusion:

Hence, the reaction is a double displacement reaction.

(e)
