Answer:

This is a redox reaction..........

Explanation:

Zinc metal is oxidized up to #Zn^(2+)#...........

#ZnrarrZn^(2+) + 2e^-# #(i.)#

Hydrogen chloride is reduced to dihydrogen..........

#2HCl(aq) +2e^(-) rarr H_2(g)uarr + 2Cl^(-)# #(ii.)#

And #(i) + (ii)# gives................

#Zn(s) + 2HCl(aq) rarr H_2(g) + ZnCl_2(aq)#
