Answer 1

The reaction represented by the equation \( \text{Mg} + 2\text{HCl} \rightarrow \text{H}_2 + \text{MgCl}_2 \) is a **single displacement reaction**.

In this type of reaction, one element (magnesium, Mg) displaces another element (hydrogen, H) from a compound (hydrochloric acid, HCl), resulting in the formation of a new compound (magnesium chloride, MgCl2) and a different elemental product (hydrogen gas, H2).
