Question

1. What is Chemical reaction? Why there is a need
of balancing a chemical reaction?​

Answer 1

Answer:

Chemical reaction is just a rearrangement of atoms. It can neither create nor destroyed during the course of a chemical reaction. Chemical equations must be balanced to satisfy the law of conservation of matter, that states that matter cannot be produced or destroyed in a closed system.

Answer 2

According to this law, mass can neither be created nor be destroyed in a chemical reaction and obeying this law the total mass of the elements or molecules present on the reactant side should be equal to the total mass of elements or molecules present on the product side.
