Answer:

See explanation

Explanation:

For reaction 3;

Molecular equation

2Na3PO4(aq) + 3CuSO4(aq) -----> 3Na2SO4(aq) + Cu3(PO4)2(s)

Complete ionic equation;

6Na^+(aq) + 2PO4^3-(aq) + 3Cu^2+(aq) + 3SO4^2-(aq) ------> 6Na^+(aq) + 3SO4^2-(aq) + Cu3(PO4)2(s)

Net ionic equation;

3Cu^2+(aq) + 2PO4^3-(aq)  -----> Cu3(PO4)2(s)

Reaction 14

Molecular equation

2FeCl3(aq) + 6NH4OH(aq) ------>2Fe(OH)3(s) + 6NH4Cl

Complete ionic equation:

2Fe^2+(aq) + 6Cl^-(aq) + 6NH4^+(aq) + 6OH^-(aq) -----> 2Fe(OH)3(s) + 6NH4^+(aq) +  6Cl^-(aq)

Net ionic equation;

2Fe^2+(aq) +  6OH^-(aq)  -----> 2Fe(OH)3(s)

2.

Al(s) + 3Ag(CH3COO)(aq) ----->Al(CH3COO)3(aq) + 3Ag(s)

Zn(NO3)2(aq) +2LiCl(aq) ------> 2LiNO3(aq) + ZnCl2(aq)

2HBr(aq) + MgSO3(s) ------>MgBr2(aq) + H2O(l) + SO2(g)

RbOH(aq) + HClO4(aq) -----> RbClO4(aq) + H2O(l)

3Sn(s) + 4H3PO4(aq)----->Sn3(PO4)4(aq) + 6H2(g)

3Li2CrO4(aq) + 2AuI3(aq) -------> 6LiI(aq) + Au2(CrO4)3(s)
