The balanced equation for the reaction between ammonia (NH₃) and hydrobromic acid (HBr) is:

NH₃(aq) + HBr(aq) → NH₄Br(aq)

Here's a breakdown of the reaction:

* Ammonia (NH₃) is a weak base.

* Hydrobromic acid (HBr) is a strong acid.

* When they react, they form ammonium bromide (NH₄Br), which is a salt.

* The reaction is an acid-base neutralization reaction.

* The state symbols (aq) indicate that all the reactants and products are dissolved in water.

Important Note: This reaction produces heat, making it an exothermic reaction.
