Chapter 14, Problem 48QP

For each of the following, write balanced half-reaction equations. Also write overall balanced equations.

$\begin{array}{l}\left(\text{a}\right)\text{ A1}\left(s\right)+\text{Fe}{\left({\text{NO}}_{\text{3}}\right)}_{\text{3}}\left(aq\right)\to \text{Al}{\left({\text{NO}}_{\text{3}}\right)}_{\text{3}}\left(aq\right)+\text{Fe}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}\left(aq\right)\hfill \\ \left(\text{b}\right)\text{ Na}\left(s\right)+{\text{HNO}}_{\text{3}}\left(aq\right)\to {\text{NaNO}}_{\text{3}}\left(aq\right)+{\text{H}}_{\text{2}}\left(g\right)\hfill \end{array}$
