Question

What is decompostion reaction xplain with example?

Answer 1

Decomposition Reaction: It is a very simple type of chemical reaction in which  a single compound splits into two or more simple substances under suitable condition. It is just opposite of combination reaction.  Thermal Decomposition (Thermolysis) reaction: In this type of reaction, a simple substance or compound is broken into two or more simple parts when heated. The reaction is endothermic as heat is required to break the bond. Electrolytic decomposition (Electrolysis) reaction: When an electric current is passed through an aqueous solution of a simple compound, it breaks in two or more parts and the process is called electrolysis.

Answer 2

when a single reactant breaks down to give simpler products , t it is called decomposition reaction example FeSO4 .7H2O and CaCO3
