Chapter 8.4, Problem 28PP

In each of the following, identify the reactant that is oxidized and the reactant that is reduced:

$\begin{array}{l}a.2Li\left(s\right)+F_2\left(g\right)\to 2LiF\left(s\right)\hfill \\ b.C{1}_2\left(g\right)+2K1\left(aq\right)\to I_2\left(s\right)+2KCI\left(aq\right)\hfill \\ c.2A1\left(s\right)+3S{n}^{2+}\left(aq\right)\to 2A{1}^{3+}\left(aq\right)+3Sn\left(s\right)\hfill \\ d.Fe\left(s\right)+CuS{O}_4\left(aq\right)\to Cu\left(s\right)+FeS{O}_4\left(aq\right)\hfill \end{array}$
