Answer 1

a) Molecular eqution (ME):
2C2H3O2Na(aq) + H2SO4(aq) -----> 2C2H3O2H(aq) + Na2SO4(aq)
Ionic equation:
2C2H3O2-(aq) + 2Na+(aq) + 2H+(aq) + SO4--(aq) -----> 2C2H3O2H(aq) + 2Na+(aq) + SO4--(aq)
Net-ionic equation:
2C2H3O2-(aq) + 2H+(aq) -----> 2C2H3O2H(aq)
acetic acid is the weak acid hence it is protonated in acidic condition rather than deprotonated form.

b) ME:
CuSO4(aq) + 4NH3(aq) --> [Cu(NH3)4]SO4(aq)
Cu2+(aq) + SO4- -(aq) + 4NH3(aq) -------> [Cu(NH3)4]SO4(aq) (complex formation)
Net Ionic equation:
Cu2+ + 4NH3(aq) --------> [Cu(NH3)4]SO4

c) ME: KI(aq) + AgNO3(aq) -----> AgI(s) + KNO3(aq)
IE: K+(aq) + I-(aq) + Ag+(aq) + NO3-(aq) -----> AgI(s) + K+(aq) + NO3-(aq)
NIE: K+(aq) + I-(aq) -----> AgI(s)

d) ME:  KI(aq) + AgNO3(aq) + 2NH3(aq) ----> [Ag(NH3)2]+(aq) + I-(aq) + K+(aq) + NO3-(aq)

IE: K+(aq) + I-(aq) + Ag+(aq) + NO3-(aq) + 2NH3(aq) ----->  [Ag(NH3)2]+(aq) + I-(aq) + K+(aq) + NO3-(aq)

NIE:  Ag+(aq) + 2NH3(aq) ----->  [Ag(NH3)2]+(aq)   complex formation

e) ME: Pb(NO3)2(aq)+K2CrO4(aq) ------> PbCrO4(s) + 2 KNO3(aq)

IE: Pb2+(aq) + 2NO3(aq) + 2K+(aq) + CrO4--(aq) ------> PbCrO4(s) + 2K+(aq) + 2NO3-(aq)

NIE Pb2+(aq) + CrO4--(aq) ------> PbCrO4(s)
