Give a complete characterization of the reaction: BaCl2 + (NH4) 2SO4 = BaSO4 + 2NH4Cl

This reaction refers to exchange reactions. Exchange reactions are reactions that occur between complex substances, while they exchange their constituent parts. This reaction takes place between salts. Each salt consists of two parts: a metal and an acidic residue. These parts are exchanged. Exchange reactions go to the end if a precipitate, gas or water is released. This exchange reaction goes to the end, as a precipitate of barium sulfate – BaSO4 – white, practically insoluble in water.
