The net ionic equation only includes the ions that undergo a chemical change. In this case, the solid Hg₂(NO₃)2 dissolves in water and dissociates into its constituent ions. The only ions that undergo a chemical change are the Hg₂²⁺ and Cl- ions, which form a solid Hg₂Cl₂. Therefore, the net ionic equation is: Hg₂²⁺(aq) + 2Cl-(aq) → Hg₂Cl₂(s). The other answer choices either do not include all the ions involved or include ions that do not undergo a chemical change.
