You need to start with a balanced equation. So balance: Na3PO4 + HCl = H3PO4 + NaCl

CaCl2 (aq) + Na3PO4 (s) >> Ca3(PO4)2 (s) + NaCl (aq) Balancing it is easy. go to the most complicated formula, and wort from there. it is Ca3(PO4)2 so you need three Ca on left then. 3 CaCl2 + Na3PO4 >> Ca3(PO4)2 + NaCl Now consider the phosphates ...

I can offer some help but it won't answer the question completely. With Na^+, Ba^+2, Cl^-, and PO4^-3, you could have these possibilities. Na3PO4 and BaCl2 or NaCl and Ba3(PO4)2. Since both are soluble in water, I think the possibility is much higher of having the Na3PO4 ...
