    Ca3(PO4)2  +  H2SO4----> CaSO4  +  H3PO4 Count the atoms on the reactant side of the quiz  P=

    Explanation
    The equation shows the reaction between Ca3(PO4)2 and H2SO4 to form CaSO4 and H3PO4. To count the number of atoms of P on the reactant side, we look at the formula for Ca3(PO4)2 which contains 2 atoms of P. Therefore, the correct answer is 2.

    Ca3(PO4)2  +  H2SO4----> CaSO4  +  H3PO4 Count the atoms on the reactant side of the quiz  O=  

    Explanation
    The given chemical equation represents a reaction between calcium phosphate (Ca3(PO4)2) and sulfuric acid (H2SO4), which produces calcium sulfate (CaSO4) and phosphoric acid (H3PO4). To count the number of oxygen atoms on the reactant side, we need to consider the subscripts in the formula. In Ca3(PO4)2, there are 8 oxygen atoms (4 from PO4 and 4 from the subscript 2). In H2SO4, there are 4 oxygen atoms (from the subscript 4). Therefore, the total number of oxygen atoms on the reactant side is 12.
