Step 1
Since you have posted question with multiple sub-parts, we are entitled to answer the first 3 only.
Step 2
a) The reactants given are
1) Calcium Iodide i.e CaI2
2) Sodium oxalate i.e Na2C2O4.
Hence the double displacement reaction taking place can be written as,
=> CaI2 (aq) + Na2C2O4 (aq) --------> CaC2O4 (s) + NaI (aq)
Balancing : Since we have 2 Na in LHS. Hence making it 2 in RHS also.
=> CaI2 (aq) + Na2C2O4 (aq) --------> CaC2O4 (s) + 2 NaI (aq)
Since all the elements are in equal number in both side of the reaction now.
Hence the reaction is now balanced.
