Answer: 1.5 mol of each
Explanation:
The balanced equation for this reaction is [tex]\text{Zn}+2\text{HCl} \longrightarrow \text{ZnCl}_{2}+\text{H}_{2}[/tex]
This means that if 3 moles of HCl are consumed (I'm assuming there is unlimited zinc), 1.5 moles of both hydrogen gas and zinc chloride will be produced.
