19. Milk of Magnesia and Heartburn

c) The neutralization reaction between Magnesium Hydroxide ( $\text{Mg(OH)}_2$ ) and Hydrochloric Acid ( $\text{HCl}$ ) produces Magnesium Chloride ( $\text{MgCl}_2$ ) and Water ( $\text{H}_2\text{O}$ ).

Write the unbalanced equation with state symbols.
$\text{Mg(OH)}_2(s) + \text{HCl}(aq) \rightarrow \text{MgCl}_2(aq) + \text{H}_2\text{O}(l)$
Balance the chlorine atoms.
There are 2 Cl on the right and 1 on the left. Place a coefficient of 2 in front of HCl.
$\text{Mg(OH)}_2(s) + 2\text{HCl}(aq) \rightarrow \text{MgCl}_2(aq) + \text{H}_2\text{O}(l)$
Balance the hydrogen and oxygen atoms.
There are $2 \text{ H (from Mg(OH)}_2) + 2 \text{ H (from HCl)} = 4$ H atoms on the left. There are 2 O atoms on the left. To balance, place a coefficient of 2 in front of $\text{H}_2\text{O}$ .
$\text{Mg(OH)}_2(s) + 2\text{HCl}(aq) \rightarrow \text{MgCl}_2(aq) + 2\text{H}_2\text{O}(l)$
Verify all atoms are balanced.
- Mg: 1 on left, 1 on right.
- O: 2 on left, 2 on right.
- H: 4 on left, 4 on right.
- Cl: 2 on left, 2 on right. The balanced chemical equation for this neutralization reaction is:
$\boxed{\text{Mg(OH)}_2(s) + 2\text{HCl}(aq) \rightarrow \text{MgCl}_2(aq) + 2\text{H}_2\text{O}(l)}$
