Answer 2

This chapter deals with various chemical reactions, their examples and corresponding chemical equations. A chemical reaction is a process in which new substances with new properties are formed. It involves rearrangement of atoms and breaking of chemical bonds.

In a chemical reaction mainly there will be two sides, one is reactant side and the other one is the product side. Two reactants combine to form products or reactants are transformed into products in a chemical reaction. The method of representing a chemical reaction with the help of symbols and formulae of the substance involved is known as chemical equations
