Final answer:
A reaction occurs when aqueous solutions of ammonium carbonate and zinc bromide are combined, resulting in a Precipitation Reaction.
Step-by-step explanation:
A reaction occurs when aqueous solutions of ammonium carbonate and zinc bromide are combined. This reaction is classified as a Precipitation Reaction. In a precipitation reaction, two solutions are mixed and yield an insoluble product called a precipitate. The reaction can be represented by the following equation:
(NH4)2CO3 (aq) + ZnBr2 (aq) -> ZnCO3 (s) + 2NH4Br (aq)
