What is the chemical product of BaNO32 H3PO4?

Overall reaction including spectator ions:

BaCl2(aq)+K2SO4(aq) --> BaSO4(s)+2KCl(aq)

Ionic Reaction:

Ba+2(aq) + 2Cl-(aq) + 2K+(aq) + SO4-2(aq) --> BaSO4(s) + 2K+(aq) + 2Cl-(aq)

Note that the BaSO4(s) is insoluble.

Net Ionic:

Ba+2(aq) + SO4-2(aq) --> BaSO4(s)

The net ionic equation eliminates the ions that just stay in solution and do not contribute to the precipitate of the barium sulfate.
