$Z n {\left(O H\right)}_{2} + 2 H C l \to Z n C {l}_{2} + 2 {H}_{2} O$

#### Explanation:

The basic equation is:
$Z n {\left(O H\right)}_{2} + H C l \to Z n C {l}_{2} + {H}_{2} O$

if we balance the Chlorine atoms

$Z n {\left(O H\right)}_{2} + 2 H C l \to Z n C {l}_{2} + {H}_{2} O$

We now have to balance the oxygen atoms

$Z n {\left(O H\right)}_{2} + 2 H C l \to Z n C {l}_{2} + 2 {H}_{2} O$

We now have the same number of each atoms of each element on each side of the equation
