1. The problem statement, all variables and given/known data Aqueous solutions of barium chloride and sodium fluoride are mixed to form a precipitate of barium fluoride. 2. Relevant equations i'm not sure but i put. BaCl + NaF = BaF2 + NaCl2 3. The attempt at a solution I'm pretty much confused whether you balance the equation. Also i'm not sure when the net equation is completed. Please help.
