Consider the following reaction.

$\displaystyle \text{Hg}{\left(\text{NO}_{{3}}\right)}_{{2}}+{2}\text{NaBr}\to\text{HgBr}_{{2}}+{2}\text{NaNO}_{{3}}$

Which species would NOT be present in the net ionic equation?

$\displaystyle \text{Hg}^{{{2}+}}$ ; $\displaystyle \text{Br}^{{-{}}}$
$\displaystyle \text{Na}^{{+}}$ ; $\displaystyle {\text{NO}_{{3}}^{{-{}}}}$
$\displaystyle \text{Hg}^{{{2}+}}$ ; $\displaystyle {\text{NO}_{{3}}^{{-{}}}}$
Na; Hg
$\displaystyle \text{Na}^{+}$ ; $\displaystyle \text{Br}^{{-{}}}$
