Explanation:

In order for an equation to be balanced, both sides must have an equal number of each element. Take for example, the reaction between Magnesium Chloride ( $M g C l_{2}$ $MgCl_2$ ) and Water ( $H_{2} O$ $H_2O$ ).
$M g C l_{2} + H_{2} O \to M g O + H C l$ $MgCl_2 + H_2O -> MgO + HCl$

First count the number of each element on either side.

Left:
$M g \to 1$ $Mg -> 1$
$C l \to 2$ $Cl -> 2$
$H \to 2$ $H -> 2$
$O \to 1$ $O -> 1$

Right:
$M g \to 1$ $Mg -> 1$
$C l \to 1$ $Cl -> 1$
$H \to 1$ $H -> 1$
$O \to 1$ $O -> 1$

To balance, we write the coefficient required to balance the number of elements on each side.

$M g C l_{2} + H_{2} O \to M g O + 2 H C l$ $MgCl_2 + H_2O -> MgO + 2HCl$

The equation is now balanced.
