Question

what is decomposition reaction? Give two examples.​

Answer 1

Answer:

A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

Answer 2

In decomposition reaction a complex compound gets broken down into two or more simpler substances. Like A = B + C

For example :

CaCo3 [Calcium Carbonate] on heating gives CaO [Calcium Oxide] and O2 [Oxygen]

Pb(NO3)2 [Lead Nitrate] on heating gives PbO [Lead oxide] No2 and O2
