Question

Give an example of each of the following types of displacement reaction:

The reaction in which a metal displaces another nonmetal.

Answer 1

1. Displacement Reaction

A displacement reaction is a reaction that comprises the replacement of one reactant with another. Depending on the number of atoms being displayed, it is classified as a single displacement reaction or a double displacement reaction.

2. Example of displacement reaction

The reaction in which a metal displaces another nonmetal is given below:

$$\begin{gathered} \mathrm{Zn}\left(\mathrm{s}\right)+2\mathrm{HCl}\left(\mathrm{aq}\right)\to {\mathrm{ZnCl}}_2\left(\mathrm{aq}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right) \\ \mathrm{Zinc}\mathrm{Hydrogen}\mathrm{Zinc}\mathrm{chloride}\mathrm{Hydrogen} \\ \mathrm{chloride} \end{gathered}$$

Here, Zinc is classified as a metal, and Chlorine is classified as a non-metal. Zinc displaces hydrogen to form Hydrogen gas with Zinc chloride. Therefore, it is an example where a metal displaces another nonmetal.
