Question

define decomposition reaction with equation thermal decomposition and decomposition by electricity ​

Answer 1

$\huge\mathfrak\pink{ANSWER}$

Classification of decomposition reaction:

Thermal composition reaction or thermolysis is the decomposition by means of heat. Electrolytic decomposition reaction or electrolysis is the decomposition by means of electricity. Photodecomposition reaction or photolysis is the decomposition by means of light.

Answer 2

Answer:

Photo decomposition is a chemical reaction in which a substance is broken down into simple substances by exposure to light (photons).

Thermal decomposition is a chemical reaction where a single substance breaks into two or more simple substances when heated. The reaction is usually endothermic because heat is required to break the bonds present in the substance.

Decomposition of calcium carbonate:Calcium carbonate (lime stone) decomposes into calcium oxide (quick lime) and carbon dioxide when heated. Quick lime is the major constituent of cement.
