Some ionic equations for reactions between metals and aqueous metal ions are given below. $\text{Cu} + 2\text{Ag}^+ \rightarrow 2\text{Ag} + \text{Cu}^{2+}$ $\text{Mg} + \text{Zn}^{2+} \rightarrow \text{Mg}^{2+} + \text{Zn}$ $\text{Zn} + \text{Cu}^{2+} \rightarrow \text{Cu} + \text{Zn}^{2+}$ $\text{Sn} + \text{Cu}^{2+} \rightarrow \text{Sn}^{2+} + \text{Cu}$ What extra information could be used to arrange copper, magnesium, silver, tin and zinc in order of their reactivity?
- AZinc reacts with $\text{Sn}^{2+}$ ions.
- BCopper does not react with $\text{Sn}^{2+}$ ions.
- CMagnesium reacts with $\text{Cu}^{2+}$ ions.
- DMagnesium reacts with $\text{Ag}^+$ ions.
