Chapter 7.5, Problem 7.42QAP

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

a. $\text{2Li}\left(s\right)+{\text{F}}_{\text{2}}\left(g\right)\to 2\text{LiF}\left(s\right)$
b. ${\text{Cl}}_{\text{2}}\left(g\right)+\text{2KI}(aq)\to {\text{I}}_{\text{2}}\left(s\right)+\text{2KCl}(aq)$
c. $\text{2Al}\left(s\right)+{\text{3Sn}}^{\text{2+}}(aq)\to \text{3Sn}\left(s\right)+{\text{ 2Al}}^{\text{3+}}(aq)$
d. $\text{Fe}\left(s\right)+{\text{CuSO}}_{\text{4}}(aq)\to \text{Cu}\left(s\right)+{\text{FeSO}}_{\text{4}}(aq)$
