i need help with the total ionic net ionic and spectator ions for?

Question

H2O+NaSO3+SO2->2NaHSO3
3Cu+8HNO3-->3Cu(NO3)2+NO+4H20
2AgNO3+Cu-->Cu(NO3)2+2Ag
Ca(CO3)+2HCl-->Mn Cl2+Cl2+2H2O

Answer 1

There are certain mistakes here.

The first one should read Na2SO3, and the equation cannot be simplified except by missing out the Na+ ions.

The second should have 2NO. The ionic equation is:

3Cu2+ + 8H+ + 2(NO3)- ---> 3Cu2+ + 2NO + 4H2O. The spectator ion is 6 of the 8 (NO3)- ions.

The third is 2Ag+ + Cu ---> Cu2+ + 2Ag, and the spectator ion is (NO3)-.

The fourth is presumably meant to be either calcium carbonate + HCl, or MnO2 + HCl. If the latter, the equation becomes:
MnO2 + 4H+ + 2Cl- ----> Mn2+ + Cl2 + 2H2O

If the former, it is:

(CO3)2- + 2H+ ---> H2O + CO2

It really does help if questions are copied out accurately!
