Solution

The correct option is A
$H_{2}$

Zn is more reactive than H. So, zinc replaces hydrogen in HCl and forms zinc chloride.

Hydrogen atom combines with another H atom and forms $H_{2}$ gas.

Zn + 2HCl $\to Z n C l_{2} + H_{2}$

So we get Zinc chloride and Hydrogen gas.

The correct option is A H2 Zn is more reactive than H. So, zinc replaces hydrogen in HCl and forms zinc chloride. Hydrogen atom combines with another H atom and forms H2 gas. Zn + 2HCl →ZnCl2+H2 So we get Zinc chloride and Hydrogen gas.
