The reaction given is:

\[ \text{Zn} + 2\text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2 \]

This is a type of reaction where one element (zinc) displaces another element (hydrogen) in a compound (hydrochloric acid), which is characteristic of a **replacement reaction** (also known as a single displacement reaction).

So, the correct answer is:

**replacement**
