11) Given the following balanced molecular equation below, choose the answer that represents the complete ionic equation. (NH4)3PO4 (aq) + FeCl3 (aq) → 3 NH4Cl (aq) + FePO4 (S) I. (NH4)3+ (aq) + PO4³ (aq) + Fe³+ (aq) + Cl3 (aq) → II. 3 NH4+ (aq) + PO4³- (aq) + Fe³+ (aq) + 3 Cl(aq) → III. 3 NH4+ (aq) + PO4³- (aq) + Fe³+ (aq) 3 Cl(aq) → (NH4)3* (aq) + PO4³- (aq) + Fe³+ (aq) + Cl³ (aq) → 3 NH4+ (aq) + PO4³- (aq) + Fe³+ (aq) 3 Cl (aq) → (NH4)3+ (aq) + PO4³- (aq) + Fe³+ (aq) + Cl3 (aq) → IV. V. VI. 3 NH4Cl (aq) + FePO4(s) 3 NH4Cl (aq) + FePO4(s) 3 NH4+ (aq) + 3 Cl (aq) + FePO4 (S) 3 NH4 (aq) + 3 Cl (aq) + FePO4 (s) 3 NH4 (aq) + 3 C (aq) + Fe³+ (s) + PO4³- (S) 3 NH4 (aq) + 3 C (aq) + Fe³+ (s) + PO4³ (s)
