Magnesium reacts with copper(II) chloride to form magnesium chloride and copper.
Mg+CuCl2→MgCl2+Cu \text{Mg} + \text{CuCl}_2 \rightarrow \text{MgCl}_2 + \text{Cu} Mg+CuCl2→MgCl2+CuWhat is the balanced ionic equation for this reaction?
Mg+Cu2+→Mg2++Cu\text{Mg} + \text{Cu}^{2+} \rightarrow \text{Mg}^{2+} + \text{Cu}Mg+Cu2+→Mg2++Cu
Mg+Cu+→Mg++Cu\text{Mg} + \text{Cu}^+ \rightarrow \text{Mg}^+ + \text{Cu}Mg+Cu+→Mg++Cu
Mg+2Cu+→Mg2++2Cu\text{Mg} + 2\text{Cu}^+ \rightarrow \text{Mg}^{2+} + 2\text{Cu}Mg+2Cu+→Mg2++2Cu
2Mg+Cu2+→2Mg++Cu2\text{Mg} + \text{Cu}^{2+} \rightarrow 2\text{Mg}^+ + \text{Cu}2Mg+Cu2+→2Mg++Cu
