Chapter 15, Problem 66APP

Use the activity series in Table 15.3 to predict whether each of the following reactions will occur spontaneously: $(15.3)$

a. $\text{Zn}(s)+{\text{Mg}}^{2+}(aq)\to {\text{Zn}}^{2+}(aq)+\mathrm{Mg}(s)$

b. $3\text{Na}(s)+{\text{Al}}^{3+}(aq)\to 3{\text{Na}}^{+}(aq)+\text{Al}(s)$

c. $\text{Mg}(s)+{\text{Ni}}^{2+}(aq)\to {\text{Mg}}^{2+}(aq)+\mathrm{Ni}(s)$
