​

Answer 1

This is an example of Reaction involving evolution of gas and a displacement reaction.

${\sf{\red{Zn(s) + 2HCl(dil) \longrightarrow \green{ZnCl_{2}(aq) +H_{2}(g)} }}}$

Answer 2

Answer:

displacement reaction

Explanation:

hydrogen is displaced by zinc in its solution when added to zinc .

•                    2HCl+Zn➡️ZnCl2+H2
