The balanced molecular equation for a reaction in acidic aqueous solution is SnCl2(aq) + 2 FeCl3(aq) → 2 FeCl2(aq) + SnCl4(aq). Which of the following is the correct net ionic equation for this process? (a) Sn2+(aq)+Fe3+(aq)→Sn4+(aq)+Fe2+(aq)\text{Sn}^{2+}(aq)+\text{Fe}^{3+}(aq)\rightarrow\text{Sn}^{4+}(aq)+\text{Fe}^{2+}(aq) (b) SnCl2(aq)+2 Fe3+(aq)→SnCl4(aq)+2 Fe2+(aq)\text{SnCl}_{2}(aq)+2\,\text{Fe}^{3+}(aq)\rightarrow\text{SnCl}_{4}(aq)+2\,\text{Fe}^{2+}(aq) (c) Sn2+(aq)+2 Fe3+(aq)→Sn4+(aq)+2 Fe2+(aq)\text{Sn}^{2+}(aq)+2\,\text{Fe}^{3+}(aq)\rightarrow\text{Sn}^{4+}(aq)+2\,\text{Fe}^{2+}(aq) (d) Sn4+(aq)+2 Fe2+(aq)→Sn2+(aq)+2 Fe3+(aq)\text{Sn}^{4+}(aq)+2\,\text{Fe}^{2+}(aq)\rightarrow\text{Sn}^{2+}(aq)+2\,\text{Fe}^{3+}(aq)
