Question

what do you know about decomposition reaction give one example of it

Answer 1

it is a type of reaction which occurs when one reactant break into two or more products for eg AB=A+B, when water breaks down to produce hydrogen and oxygen gases .thus happens when an electric current pass through the water

Answer 2

A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds. These reactions often involve an energy source such as heat, light, or electricity that breaks apart the bonds of compounds.
The general form for a decomposition reaction is AB → A + B

Decomposition Reaction Examples

1. the spontaneous decomposition of hydrogen peroxide into water and oxygen:

2 H2O2 → 2 H2O + O2

2. The decomposition of potassium chlorate into potassium chloride and oxygen is yet another example:

2 KClO3 → 2 KCl + 3 O2
