    Na₃PO₄ + HBr

    Explanation:

    To find the product of the reactants NaBr + H₃PO₄ decide what type of reaction it would likely be.

    There are four elements, so it would be double displacement (where each element/polyatomic ion changes its partner). Since the reactions are not an acid (begins with H) and a base (ends with OH), it is not neutralization.

    Identify what type of elements/polyatomics they are:

    In NaBr, Na is metal and Br is non-metal.

    In H₃PO₄, H is a metal and PO₄ is a non-metal.

    Bonds only form between two non-metals, or between a non-metal and a metal; it's never metal + metal.

    NaBr + H₃PO₄ = > NaPO₄ + HBr

    Here, the non-metals switched places to form new bonds.

    Fix the number of atoms:

    In each of the products, use the "criss-cross" rule, where each element has the same number of atoms as its partner's charge.

    Put brackets around polyatomic ions, in this case PO₄ phosphate.

    NaBr + H₃PO₄ = > Na (PO₄) + HBr

    Since (PO₄) has a charge of - 3, which you can find on your polyatomic ions charts, its partner Na will get 3 atoms.

    Since Na has a charge of + 1, PO₄ gets 1 atom.

    Bromide has a charge of - 1, so hydrogen gets 1 atom.

    NaBr + H₃PO₄ = > Na₃ (PO₄) ₁ + H₁Br₁

    Remove the brackets and any ₁ subscripts.

    NaBr + H₃PO₄ = > Na₃PO₄ + HBr
