Multiple Choice

Which of the following represents the complete ionic equation for the reaction of aqueous Hg2(NO3)2 with aqueous NaCl to form solid Hg2Cl2 and aqueous NaNO3?

Hg2^2+(aq) + 2Cl^-(aq) → Hg2Cl2(s)

Hg2^2+(aq) + 2Na+(aq) + 2Cl^-(aq) → Hg2Cl2(s) + 2NaNO3(aq)

Hg2(NO3)2(aq) + 2NaCl(aq) → Hg2Cl2(s) + 2NaNO3(aq)

Hg2^2+(aq) + 2NO3^-(aq) + 2Na+(aq) + 2Cl^-(aq) → Hg2Cl2(s) + 2Na+(aq) + 2NO3^-(aq)

Verified step by step guidance

Identify the reactants and products in the given chemical reaction: Hg2(NO3)2(aq) and NaCl(aq) are the reactants, while Hg2Cl2(s) and NaNO3(aq) are the products.

Write the balanced molecular equation for the reaction: Hg2(NO3)2(aq) + 2NaCl(aq) → Hg2Cl2(s) + 2NaNO3(aq).

Break down the aqueous compounds into their respective ions to form the complete ionic equation. For Hg2(NO3)2(aq), it dissociates into Hg2^2+(aq) and 2NO3^-(aq). For 2NaCl(aq), it dissociates into 2Na+(aq) and 2Cl^-(aq).

Write the complete ionic equation by including all the ions from the dissociated reactants and the solid product: Hg2^2+(aq) + 2NO3^-(aq) + 2Na+(aq) + 2Cl^-(aq) → Hg2Cl2(s) + 2Na+(aq) + 2NO3^-(aq).

Identify the spectator ions, which are ions that appear on both sides of the equation and do not participate in the formation of the precipitate. In this case, the spectator ions are 2Na+(aq) and 2NO3^-(aq).
