Answer

Explanation:

Step1: Identify reaction type

This is a double - displacement reaction. In a double - displacement reaction of the form (AB + CD\rightarrow AD+CB), where (A = Na^+), (B = Br^-), (C = Cu^{2 +}), and (D=PO_{4}^{3 -}).

Step2: Determine correct products

The balanced chemical equation for the reaction (3NaBr(aq)+Cu_3(PO_4)_2(aq)\rightarrow Na_3PO_4(aq)+3CuBr_2(s)). Copper(II) bromide ((CuBr_2)) is insoluble in water and forms a solid precipitate, while sodium phosphate ((Na_3PO_4)) remains in aqueous solution.

Answer:

B. (CuBr_2(s)+Na_3PO_4(aq))
