•Displacement Reaction - Those reactions which are accompanied by the exchange of ions of both the compounds are called Displacement Reactions.

Eg. zncl2 +( na)2 so4 ➡2 nacl + znso4 .

•Decomposition Reaction-Those reactions in which a compound gets split into two or more
units are called Decomposition Reactions

Eg. caco3 ➡ cao + co2 .
