decomposition reaction and their prts
Answers
Answer:
----------------------
(1) in this reaction 1 reactant decomposes to give 2 or more products.
(2) Can be due to electricity, sunlight and heat ect.
(2) They produce a PRECIPITATE and also are called precipitation reaction .

DECOMPOSITION REACTION: The reaction in which a compound breaks up into two or more simpler substances are known as decomposition reaction.
TYPES:
1) Thermal decomposition: When decomposition reaction is carried out by heat then it is called thermal decomposition reaction.
Ex:- CaCO3-----> CaO+ CO2
2) Photolytic decomposition: When decomposition reaction is carried out by light then it is called photolytic decomposition reaction.
Ex:- 2AgCl--------> 2Ag+ Cl2
3) Electrolytic decomposition: When decomposition reaction is carried out by electricity then it is called Electrolytic decomposition reaction.
Ex:- 2H2O---------> 2H2+ O2
