Question

Differentiate combination reaction and decomposition reaction with the help of examples

Answer 1

Answer:

A photodecomposition reaction is a type of decomposition reaction in which the reactant is broken down to its constituents by absorbing energy from photons. An example of a photo decomposition reaction is the decomposition into dioxygen and an oxygen radical, as represented by the chemical equation provided below.

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

Answer:

reactions in which two substance can combine each other and form a single substance known as combination reaction

2h2 +O2-------2h2O
