Identify the Net Ionic Equation for the Reaction (If Any)

Multiple Choice

Identify the net ionic equation for the reaction (if any) that occurs when aqueous solutions of K₂S and Fe(NO₃) ₂ are mixed.

A) K⁺(aq) + NO₃^-(aq) → KNO₃(s)
B) Fe²⁺(aq) + S^2-(aq) + 2K⁺(aq) + 2NO₃^-(aq) → FeS(s) + 2K⁺(aq) + 2NO₃^-(aq)
C) Fe²⁺(aq) + S^2-(aq) + 2K⁺(aq) + 2NO₃^-(aq) → Fe²⁺(aq) + S^2-(aq) + 2KNO₃(s)
D) Fe²⁺(aq) + S^2-(aq) → FeS(s)
E) No reaction occurs.
