Differentiate between the following
Answers
1.
Thermal decomposition :- On heating, potassium chlorate (KCIO3) decomposes into potassium chloride (KCI) and oxygen (O2) but on cooling, KCl and O2 do not combine to form KCIO3 Thus, thermal decomposition is irreversible reaction.
Thermal Dissociation:- When on heating a compound, its molecule breaks up into two or more smaller molecules of other compounds and recombine, on cooling, to form the Molecule of the original compound, the reaction is called as thermal dissociation.
2.
Neutralization reaction:- A neutralization reaction is a double displacement reaction taking place between the acids and the bases.
Precipitation reaction :- Precipitation reaction is a double displacement reaction taking place between two aqueous ionic compounds which forms a new insoluble ionic compound.
3.
Electrolytic decomposition:-Electrolytic decomposition is breakdown by electricity.
Photochemical decomposition :-Photochemical decomposition is breakdown in presence of chemicals with help of sunlight.
