Explanation / Answer

1)

Balanced molecular equation,

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

Ionic equation,

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

Net ionic equation,

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

2)

Balanced molecular equation,

NiCl2 (aq) + 2 AgNO3 (aq) ------> 2 AgCl (s) + Ni(NO3)2 (aq)

Ionic equation,

Ni+2 + 2 Cl- + 2 Ag+ + NO3- -------> 2 AgCl (s) + Ni+2 + 2 NO3-

Net ionic equation,

Ag+ (aq) + Cl- (aq) --------> AgCl (s)

3)

Balanced molecular equation,

NiCl2 (aq) + Na2CO3 (aq) ------> NiCO3 (s) + 2 NaCl (aq)

Ionic equation,

Ni+2 + 2 Cl- + 2 Na+ + Co3 2- -------> NiCO3 (s) + 2 Na+ + 2 Cl-

Net ionic equation,

Ni+2 (aq) + CO3 2- (aq) --------> NiCO3 (s)

4)

Balanced molecular equation,

KCl (aq) + NaNO3 (aq) -------> KNO3 (aq) + NaCl (aq)

Ionic equation,

K+ (aq) + Cl- (aq) + Na+ (aq) + NO3- (aq) ------> K+ (aq) + NO3- (aq) + Na+ (aq) + Cl-(aq)

All compound are water soluble so no net reaction is observed

5)

Balanced moleular equation,

Pb(NO3)2 (aq) + H2SO4 (aq) ------> PbSO4 (s) + 2 HNO3 (aq)

Ionic equation,

Pb+2 (aq) + 2 NO3- (aq) + 2 H+ (aq) + SO4 2- (aq) -------> PbSO4 (s) + 2 H+ (aq) + 2 NO3- (aq)

Net ionic equation,

Pb+2 (aq) + SO4 2- (aq) --------> PbSO4 (s)
