Answer 1

The reaction \( \text{Zn} + 2\text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2 \) is classified as a single-replacement reaction. In this type of reaction, one element replaces another in a compound. In this case, zinc (Zn) replaces hydrogen (H) in hydrochloric acid (HCl).

So the correct answer is: single-replacement.
