Zn+HCI =

When zinc (Zn) reacts with hydrochloric acid (HCl), it produces zinc chloride (ZnCl₂) and hydrogen gas (H₂). The balanced chemical equation for this reaction is:

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

In this reaction, zinc displaces hydrogen from hydrochloric acid, resulting in the formation of zinc chloride and the release of hydrogen gas.
