Explanation:
Chemical reaction:
In a chemical reaction one or more substance converted into the another substance.
The substances that reacts or combine during the chemical reaction are called reactants while the new species formed as a result of chemical reaction are products.
There are different types of reaction given below:
Decomposition reaction:

AB → A + B
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
Single replacement:
It is the reaction in which one elements replace the other element in compound.
