Question

explain decomposition reaction with the help of example? (in brief)

Answer 1

Decomposition is a type of chemical reaction.  It is defined as the reaction in which a single compound splits into two or more simple substances under suitable conditions. It is just the opposite of the combination reaction.

In a combination reaction, a substance is formed as a result of chemical combination, while in a decomposition reaction, the substance breaks into new substances.



 

For example:  The digestion of food in our body is accompanied by a number of decomposition reactions. The major constituents of our food such as carbohydrates, fats, proteins, etc.,decompose to form a number of simpler substances.  These substances further react, releasing large amounts of energy, which keeps our body working.

Answer 2

the reaction in which a compound is broken into its chemical elements with the action of heat in various forms is decomposition reaction . eg.
silver chloride in sunlight gives 2Ag+Cl2
