Chapter 19, Problem 24E

Write a cell diagram and call diagram the value of $E_{\text{col}}^{°}$for a voltaic cell in which
a ${\text{Cl}}_{\text{2}}\left(\text{g}\right)$ is reduced to ${\text{Cr}}^{\text{-}}\left(\text{aq}\right)$ and Fe(s) is oxidized to ${\text{Fe}}^{\text{2+}}\left(\text{aq}\right)$ ;
b ${\text{Ag}}^{\text{+}}\left(\text{aq}\right)$ is displaced from solution by Zn(s):
c. The cell reaction ${\text{2Cu}}^4\left(\text{aq}\right)\to {\text{Cu}}^{\text{2+}}\left(\text{aq}\right)+\text{Cu}\left(\text{s}\right)$ .
d. ${\text{MgBr}}_{\text{2}}\left(\text{g}\right)$ is produced from Mg(s) and ${\text{Br}}_{\text{2}}\left(\text{l}\right)$ .
