Question

Zn + 2HCI -> ZnCh + H2
Which type of reaction is this?
(1 point)
• single-replacement
• ionic
• electronegative
O combustion

Answer 1

The reaction \( \text{Zn} + 2\text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2 \) is a single-replacement reaction. In this type of reaction, one element (zinc) displaces another element (hydrogen in hydrochloric acid) from a compound. Therefore, the correct answer is:

• single-replacement
