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)
