Question about balancing, total ionic equation, and net ionic equation?

Balanced equation :
   you need to know the charges.  If Na has a charge of 2+ and Cl has a charge of 1- than the aqueous solution in the beginning would be NaCl2.  Then you just have to make sure that there is the same amount of everything on each side.

Total ionic :
    to do this you will need to break everything up to its simplist form.  NaCl2 will become Na^2+ and Cl^1-.  Th only thing that doesn't change is the solid product, AgCl (s)

Net ionic :
    take what you got in the total ionic, now only put back in the net ionic the elements that make up the product.  ( Ag+  +  Cl-  =  AgCl )
