Chapter 5, Problem 66RQ

Use Table 5.3 to predict the outcome of the following reactions. If no reaction occurs, write N.R. If a reaction occurs, write a balanced chemical equation for it.

$\begin{array}{l}\left(\text{a}\right){\text{Fe+Mg}}^{\text{2+}}\stackrel{}{\to }\left(\text{c}\right){\text{Ag}}^{\text{+}}\text{+Fe}\stackrel{}{\to }\hfill \\ \left(\text{b}\right){\text{Cr +Fb}}^{\text{2}}\stackrel{}{\to }\left(\text{d}\right){\text{ Ag + Au}}^{\text{3+}}\stackrel{}{\to }\hfill \end{array}$
