Answer: The balanced chemical equation is given below.
Step-by-step explanation:
Every balanced chemical equation follows law of conservation of mass.
This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This law also states that total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.
For the given reaction, the balance chemical equation follows:

By stoichiometry of the reaction:
6 moles of sodium bromide reacts with 1 mole of calcium phosphate to produce 3 moles of calcium bromide and 2 moles of sodium phosphate.
