Give the net iоnic equаtiоn fоr the reаction (if аny) that occurs when aqueous solutions of K2S and Fe(NO3)2 are mixed.A) K+(aq) + NO3-(aq) → KNO3(s)B) Fe2+(aq) + S2-(aq) + 2 K+(aq) + 2 NO3-(aq) → FeS(s) + 2 K+(aq) + 2 NO3-(aq)C) Fe2+(aq) + S2-(aq) + 2 K+(aq) + 2 NO3-(aq) → Fe2+(aq) + S2-(aq) + 2 KNO3(s)D) Fe2+(aq) + S2-(aq) → FeS(s)E) No reaction occurs.
