Question

Write the balanced chemical equation for the reaction of iron with dilute hydrochloric acid.

Answer 1

Balancing of chemical equations:

Balancing of chemical equations may be defined as - “The process of making the number of different types of elements, on both sides of the equation, equal.”

In a balanced equation, the number of atoms of different elements on both sides of the equation is always equal.

The balancing of a chemical equation is essential or necessary to fulfill the requirement of the “Law of conservation of mass”.

The balanced chemical equation for the reaction of iron with dilute hydrochloric acid is as follows.

$$\begin{gathered} \mathrm{Fe}+2\mathrm{HCl}\to {\mathrm{FeCl}}_2+{\mathrm{H}}_2 \\ \left(\mathrm{Iron}\right)\left(\mathrm{Dilute}\mathrm{hydrochloric}\mathrm{acid}\right)\left(\mathrm{Ferrous}\mathrm{chloride}\right)\left(\mathrm{Hydrogen}\mathrm{gas}\right) \end{gathered}$$
