Question

How many types of reactions of decomposition and which reaction is responsible for breathing (oxygen)
And give some example of each reactions ​

Answer 1

Answer:

Electrolytic decomposition reaction or electrolysis is the decomposition by means of electricity. Photodecomposition reaction or photolysis is the decomposition by means of light. Decomposition reaction can be classified into three types.

Answer 2

There are three types of decomposition reactions: Thermal decomposition reactions; Elctrolytic decomposition reactions; Photo decomposition reactions.

(Thermal decomposition reaction is responsible for breathing. )

Heat energy is released from cells during respiration. Also, heat is used in breaking up glucose to release energy. Hence, respiration is a thermal decomposition reaction, or more specifically, an exothermic reaction.
