Question

explain types of chemical reaction in detail. ( each type of reaction must be explained with example , definition)
please guys help me it's very important ​

Answer 1

Answer:

Types of reactions:-

1. Combination Reaction:- The reaction in which two or more substances combine to form a single product is known as Combination Reaction.

Ca(OH)_2}Eg.:−Ca(s)+H2O(l)⟶Ca(OH)2

Most of the combination reactions are exothermic reaction. It is because in most of the combination reactions heat is evolved.

* Exothermic Reaction:- The reaction in which heat is evolved is known as Exothermic Reaction.

2. Decomposition Reaction:- The reaction in which one single reactant decomposes to form two or more products is known as Decomposition reaction

Most of the decomposition reactions are endothermic reactions. It is because most of the decompostion reactions absorb heat.

*Endothermic Reaction:- The reaction in which heat is absorbed is known as Endothermic Reaction.

3. Displacement Reaction:- The reaction in which a more reactive metal displaces a less reactive metal in a compound is known as Displacement Reaction.

Some more reactions:-

1. Double Displacement Reaction:- The reaction in which exchange of ions between two compounds to form a new compound takes place is known as Double Displacement Reaction.

2. Thermal Decomposition Reaction:- When Decomposition Reaction take place in the presence of heat they are called Thermal Decomposition Reaction.

3. Photochemical Decomposition:- When decomposition reaction takes place under the sunlight, they are called Photochemical Reaction.

4. Electrolysis:- When substance decomposes by the passage of electricity into it, the reaction is termed as Electrolysis.
