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

I have



1.H2SO4+Ba(OH)2



2. Cu(C2H3O2)2 + H2C2O4



3. CuSO4+H2C2O4



I have to write that in A) molecular equation, B) total ionic, and C) net ionic equation. I sort of have an idea but these ones are confusing me!!

How do you write the Total and Net Ionic equations for these substances?
1) A) H2SO4(aq) + Ba(OH)2(aq) ---%26gt; BaSO4(s) + 2H2O(l)



B) 2H(1+)(aq) + SO4(2-)(aq) + Ba(2+)(aq) + 2OH(1-)(aq) ---%26gt;

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) ---%26gt;

CuC2O4(s) + 2HC2H3O2(aq)



B) Cu(2+)(aq) + 2C2H3O2(1-)(aq) + 2H(1+)(aq) + C2O4(2-)(aq) ---%26gt;

CuC2O4(s) + 2H(1+)(aq) + 2C2H3O2(1-)(aq)



C) Cu(2+)(aq) + C2O4(2-)(aq) ---%26gt; CuC2O4(s)



3) A) CuSO4(aq) + H2C2O4(aq) ---%26gt; CuC2O4(s) + H2SO4(aq)



B) Cu(2+)(aq) + SO4(2-)(aq) + 2H(1+)(aq) + C2O4(2-)(aq) ---%26gt;

CuC2O4(s) + 2H(1+)(aq) + SO4(2-)(aq)



C) Cu(2+)(aq) + C2O4(2-)(aq) ---%26gt; CuC2O4(s)
