It is Copper(II) bromide = CuBr2
It is a single displacement reaction. No balancing is needed in the resulting equation. Zn + CuBr2 ----> ZnBr2 + Cu
Zn + CuBr2 = Cu + ZnBr2
The percent composition for CuBr2 is: Cu= 28.45% Br= 71.55%

There are two atoms of Bromine (Br) and one atom of Copper (Cu) in this compound. Thus, there are two elements, but three atoms.
Na3PO4+CuBr2=Cu3(PO4)2+NaBr PO4 has a charge of -3 and Cu (in this equation as shown by CuBr2) has a charge of +2, when they combine you switch the chareges and add them on as subscripts to each other. Na and Br have the opposite charges, -1 and +1, so you don't have to add them to the equation.
