How do you write the Total and Net Ionic equations for these substances?

1) A) H2SO4(aq) + Ba(OH)2(aq) ---> BaSO4(s) + 2H2O(l)

B) 2H(1+)(aq) + SO4(2-)(aq) + Ba(2+)(aq) + 2OH(1-)(aq) --->
BaSO4(s) + 2H2O(l)

C) The net ionic equation is the same as the total ionic equation on this one because there are no spectator ions.

2) A) Cu(C2H3O2)2(aq) + H2C2O4(aq) --->
CuC2O4(s) + 2HC2H3O2(aq)

B) Cu(2+)(aq) + 2C2H3O2(1-)(aq) + 2H(1+)(aq) + C2O4(2-)(aq) --->
CuC2O4(s) + 2H(1+)(aq) + 2C2H3O2(1-)(aq)

C) Cu(2+)(aq) + C2O4(2-)(aq) ---> CuC2O4(s)

3) A) CuSO4(aq) + H2C2O4(aq) ---> CuC2O4(s) + H2SO4(aq)

B) Cu(2+)(aq) + SO4(2-)(aq) + 2H(1+)(aq) + C2O4(2-)(aq) --->
CuC2O4(s) + 2H(1+)(aq) + SO4(2-)(aq)

C) Cu(2+)(aq) + C2O4(2-)(aq) ---> CuC2O4(s)
