Explanation / Answer
1) aqueous solutions of chromium(II) iodide and barium nitrate
write the formula of the given compound and complete the reaciton and balace it.
Formula equation:
CrI2 (aq) + Ba(NO3)2 (aq) -----------> BaI2 (aq) + Cr(NO3)2(aq)
(we get the solubilities of the products from solubility table)
Complete ionic equation:
All the aqeuous(aq) compounds are ionized
Cr+2(aq) + 2I- (aq) + Ba2+(aq) + 2NO3- (aq) -----------> Ba2+(aq) + 2I- (aq) + Cr+2( aq) + 2NO3- (aq)
Here all the ions are remained in the aqueous solution
No reaction occurs or no net ionic equation.

2) aqueous solutions of calcium bromide and lead(II) nitrate are combined.
Formula equation:
CaBr2 (aq) + Pb(NO3)2 (aq) -----------> PbBr2 (s) + Ca(NO3)2(aq)
Complete ionic equation:
All the aqeuous compounds are ionized. Solids(s) wont ionize.
Ca+2(aq) + 2Br- (aq) + Pb2+(aq) + 2NO3- (aq) -----------> PbBr2 (s) + Ca+2( aq) + 2NO3- (aq)
Net-ionic equation
we get net-ionic equation by removing spectator ions. (spectator ions are those ions present in solution before and after the reaction)
2Br- (aq) + Pb2+(aq) ------> PbBr2 (s)
---------------------------------------------
3) aqueous solutions of barium bromide and magnesium sulfate are combined.
Formula equation:
BaBr2 (aq) + MgSO4 (aq) -----------> MgBr2 (s) + BaSO4(s)
Complete ionic equation:
Ba+2(aq) + 2Br- (aq) + Mg2+(aq) + SO42-(aq) -----------> BaSO4(s) + Mg+2( aq) + 2Br- (aq)
Net-ionic equation
we get net-ionic equation by removing spectator ions.
Ba+2(aq) + SO42-(aq) -----------> BaSO4(s)
Similarly we can solve reamaining
16. aqueous solutions of chromium(III) sulfate and lead(II) nitrate are combined.
Formula equation:
Cr2(SO4)3 (aq) + 3Pb(NO3)2 (aq) -----------> 2Cr(NO3)3 (aq) + 3PbSO4(s)
Complete ionic equation:
2Cr+3(aq) + 3SO42-(aq) + 3Pb2+(aq) + 6NO3- (aq) -----------> 3PbSO4(s) + 2Cr+3(aq) + 6NO3- (aq)
Net-ionic equation
we get net-ionic equation by removing spectator ions.
3Pb2+(aq) + 3SO42-(aq) ----------> 3PbSO4(s)
