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

Explanation:

The net reaction is $Z n (s) + 2 H^{+} (a q) \to Z n^{2 +} (a q) + H_{2} (g)$ $Zn(s)+2H^+(aq) ->Zn^(2+)(aq)+H_2(g)$
The $C l^{-}$ $Cl^-$ ions are spectators - they don't change.

This experiment includes the reaction of zinc with hydrochloric acid. The experiment compares reactivity of three metals; magnesium, zinc and copper. The video includes a discussion of writing balanced equations for all the observed reactions.
