Question

Explain decomposition reaction

Answer 1

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.


I hope you are clear with the term chemical reaction.

A chemical reaction is a process by which the atoms of one or more substances are rearranged to form different substances. There are many types of chemical reactions. These reactions are often classified by what they form or what happens during the course of the reaction.

Examples of Decomposition Reactions

A simple way to visualize a decomposition reaction is to use generic terms. Let's pretend we have discovered an elusive compound with the chemical formula 'AZ.' This means the compound is composed of an imaginary element 'A' bonded to imaginary element 'Z.' If we have a reaction equation that says 'AZ' yields 'A' + 'Z,' it shows a decomposition reaction. This decomposition reaction example breaks one compound down into two elements.

There are 4 types of chemical reactions.

• Synthesis.

• Decomposition.

• Displacement.

• Combustion.

Decomposition Reaction :

Decomposition is the breaking up of a single compound into two or more simpler products. Energy is needed to break bonds.

Thermal decomposition is the use of heat to break down a compound. When copper carbonate is heated it changes from a green powder to a black powder. The green copper carbonate breaks down into black copper oxide and carbon Dioxide.

Example :

Cu2(OH)2CO3 ====> CuO + CO2.
