Answer 1

HOPE THIS WILL HELP

A displacement reaction is a chemical reaction that occurs by replacing a chemical species in a molecule by another chemical species. Displacement reactions take place in the presence of a more reactive species which has a high binding affinity for a cation or an anion present in a compound. The reactive species can be a metal element, anion or a cation. The general form of a displacement reaction can be given as below.

A double displacement reaction is a chemical reaction that involves the exchange of two ionic species between two different molecules. The formed product is a new compound which can be either a liquid or a solid. The general form of this kind of reactions is given below.
