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

Zinc metal is oxidized up to $Z n^{2 +}$ $Zn^(2+)$ ...........

$Z n \to Z n^{2 +} + 2 e^{-}$ $ZnrarrZn^(2+) + 2e^-$ $(i .)$ $(i.)$

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

$2 H C l (a q) + 2 e^{-} \to H_{2} (g) ↑ ⏐ + 2 C l^{-}$ $2HCl(aq) +2e^(-) rarr H_2(g)uarr + 2Cl^(-)$ $(i i .)$ $(ii.)$

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

$Z n (s) + 2 H C l (a q) \to H_{2} (g) + Z n C l_{2} (a q)$ $Zn(s) + 2HCl(aq) rarr H_2(g) + ZnCl_2(aq)$

What is this equation an example of: Zn+2HCl→ZnCl2+H2Zn + 2HCl -> ZnCl_2 + H_2?
