Question

How chemical displacement reactions differ from chemical decomposition reaction? Explainwith an example for each.

Answer 1

A chemical reaction in which a single compound splits into two or more simple substances is called a decomposition reaction. ... 3.Displacement Reaction: Reactions in which the more reactive element displaces the less reactive element from its compound are called displacement 

Answer 2

Displacement reaction: The chemical reaction in which highly reactive element displaces low reactive element from its salt to produce new substance is called displacement reaction.
example :CuSo4+Zn--------ZnSo4+Cu

Decomposition reaction : The chemical reaction in which a single compound is decomposed into two or more new substance.
All decomposition reactions are endothermic.
Example :H2O _electricity ______ > H2+O2
