Does anyone know this net ionic equation? Please help!?

First you need to multiply NaBr by 2 because of the product NaCl2 is not equal you need 2Na therefore Cl2(g) + 2NaBr(aq) --> 2NaCl (aq) + Br2(g) that is the full balanced equation, the only thing that had a reaction is the Br so the net ionic equation is 2Br-(aq)--->Br2(g)
