Question 7
H

Zinc reacts with dilute sulfuric acid to produce zinc sulfate solution and hydrogen.

Which ionic equation represents this reaction?

[1]
A

Zn+SO42−→ZnSO4\text{Zn} + \text{SO}_4^{2-} \rightarrow \text{ZnSO}_4Zn+SO42−​→ZnSO4​

B

Zn2++2H+→Zn+H2\text{Zn}^{2+} + 2\text{H}^+ \rightarrow \text{Zn} + \text{H}_2Zn2++2H+→Zn+H2​

C

Zn2++H2→Zn+2H+\text{Zn}^{2+} + \text{H}_2 \rightarrow \text{Zn} + 2\text{H}^+Zn2++H2​→Zn+2H+

D

Zn+2H+→Zn2++H2\text{Zn} + 2\text{H}^+ \rightarrow \text{Zn}^{2+} + \text{H}_2Zn+2H+→Zn2++H2​
