Explanation / Answer

The equation is:

HBr(aq) + NH3(aq) ------> NH4Br

It is like acid base reaction to give a salt ammonium bromide.

Ionic equation:

HBr + H2O -----------> H3O+ + Br-
H3O+ +   NH3 -----------> NH4+ + H2O
NH4+   + Br- ---------> NH4Br
___________________________________________

HBr + NH3 ---------> NH4Br

HBr is a strong acid and NH3 is a weak base.
So, strong acid + weak base.

The extent of the reaction is 100%.
