If a piece of copper is added to aqueous silver nitrate, a displacement reaction occurs. What is the ionic equation for the reaction that occurs?
- A$\text{Ag}^+(aq) + \text{Cu}(s) \rightarrow \text{Ag}(s) + \text{Cu}^{2+}(aq) + e^-$
- B$2\text{Ag}^+(aq) + \text{Cu}(s) \rightarrow 2\text{Ag}(s) + \text{Cu}^{2+}(aq)$
- C$2\text{AgNO}_3(aq) + \text{Cu}(s) \rightarrow 2\text{Ag}(s) + \text{Cu(NO}_3\text{)}_2(aq)$
- D$2\text{Ag}(s) + \text{Cu}^{2+}(aq) \rightarrow 2\text{Ag}^+(aq) + \text{Cu}(s)$
