Complete ionic equation and net ionic equation


In a problem they give me an initial reaction that I have to complete and balance, after that put the complete ionic equation and the net ionic equation.
AgBr (s) + BaCl2 (aq) →
Molecular equation.
AgBr (s) + BaCl2 (aq) → AgCl2 (s) + BaBr (aq)
Complete ionic equation.
AgBr (s) + Ba+2 (aq) + Cl2-1 (aq) → AgCl2 (s) + Ba+2 (aq) + Br-2 (aq)
Spectator ions: Ba + 2 (ac)
AgBr (s) + Ba+2 (aq) + Cl2-1 (aq) → AgCl2 (s) + Ba+2 (aq) + Br-2 (aq)
Net ionic equation.
AgBr (s) + Cl2-1 (aq) → AgCl2 (s) + Br-2 (aq)

It's okay like that? I have doubts if a solid state (s) is found in the reactants and another solid state is in the products, if the molecular ion and net ionic equations can be performed.
I appreciate if anyone can help me.

First check the oxidation number of silver. All what you wrote is wrong. The second thing is
check the solubility products of silverchloride and - bromide,.can this reaction happen?

All bromides are soluble except Ag+, Pb+2, Hg2 +2 halides, the compound 2AgBr (s)
All chlorides are soluble, except Ag+, Pb+2, Hg2 +2 halides, the compound 2AgCl (s)

The correct balance of the equation would be this?
2AgBr (s) + BaCl2 (aq) = 2AgCl (s) + BaBr2 (aq)

Oxidation number.
BaCl2 (aq)
Ba +2
Cl2 -1
2AgBr (s)
Ag +1
Br -1
2AgCl (s)
Ag +1
Cl -1
BaBr2 (aq)
Ba +2
Br2 -1

When i can identify the balanced equation, i will be able to do the complete ionic equation and the net ionic equation.

Compare the soloubilities and soloubility products of AgCl and AgBr. What has better soloubilty. Does this reaction take place?
