Homework Help: chem 11

Posted by Anonymous on Sunday, July 18, 2010 at 7:15pm.

You have 2 chemicals A (solid) and B (solid), but you do not know the exact composition of either one of them. You do know that all together, there is SOME combination of sodium, barium, chloride and phosphate (PO4^3-) present. You dissolve both chemicals in water. Then you mix A and B together. You observe there is a cloudy precipitate that forms in a clear colorless solution (mostly water?)

Predict and write 2 possible balances equations for the 2 most likely reactions that could've ocurred.

PLEASE HELP. I don't know how to start, or what to do. i just need to figure out what goes where and how i know where to put things. I can balance the equation myself, i just need help on how to figure out what to do. Thanks
