    Answer:

    Ba(OH)₂ + 2 HBr ⇒ BaBr₂ + 2 H₂O

    Explanation:

    We have the products of a reaction and we have to predict the reactants. Since the products are binary salt and water, this must be a neutralization reaction. In neutralizations, acids react with bases. The acid that gives place to Br⁻ is HBr, while the base the gives place to Ba²⁺ is Ba(OH)₂. The balanced chemical equation is:

    Ba(OH)₂ + 2 HBr ⇒ BaBr₂ + 2 H₂O
