The balanced chemical equation for the reaction between calcium acetate (Ca(CH3COO)2) and sodium phosphate (Na3PO4) is:

3Ca(CH3COO)2 + 2Na3PO4 -> Ca3(PO4)2 + 6CH3COONa

This equation shows that 3 moles of calcium acetate react with 2 moles of sodium phosphate to produce 1 mole of calcium phosphate and 6 moles of sodium acetate.
