Which Equation Best Represents the Net Ionic Equation for the Reaction

Multiple Choice

Which equation best represents the net ionic equation for the reaction that occurs when aqueous solutions of potassium phosphate and iron(II) nitrate are mixed?

A) 3Fe²⁺(aq) + 2PO₄^3-(aq) → Fe₃(PO₄) ₂(s)
B) 2K⁺(aq) + Fe(NO₃) ₂(aq) → 2KNO₃(aq) + Fe²⁺(aq)
C) 3Fe²⁺(aq) + 2PO₄^3-(aq) → Fe₃(PO₄) ₂(aq)
D) 2K₃PO₄(aq) + 3Fe²⁺(aq) → Fe₃(PO₄) ₂(s) + (K⁺) ₆(aq)
E) 2K₃PO₄(aq) + 3Fe(NO₃) ₂(aq) → Fe₃(PO₄) ₂(s) + 6KNO₃(aq)
