Hiii guys..........

Plz ans the Question....

What are the different types with example...
Perfect ans will b marked as Brainliest ☺.........

Plz ans this fast. ...☺

Answer 1

Those reaction in which a compound splits up into two or more simpler substances are known as decomposition reaction.

For example- CaCO3 Arrow ^heat CaO +CO2

When calcium carbonate is heated then it formed calcium oxide and carbon dioxide.

Answer 2

Hola there,

Decomposition reaction.

In such reaction, a single reactant breaks down to give simpler products.

AB --› A + B

Ex: CaCO3 --heat--› CaO + CO2

There are three types of decomposition reaction.

1) Thermal decomposition: When a decomposition reaction is carried out by heating, it is called a thermal decomposition reaction.

Ex: 2FeSO4 --Heat--› Fe2O3 + SO2 + SO3

2) Photochemical decomposition: If the energy of sunlight is used to carry out the decomposition reaction, it is called photochemical decomposition.

Ex: 2AgBr --sunlight--› 2Ag + Br2

3) Electrolytic decomposition: If the electric current is used to carry out decomposition reaction. It is called electrolytic decomposition.

Ex: 2H2O ---› 2H2 + O2

Hope this helps...:)
