Question

what is a chemical reaction??

Answer 1

a process that involves rearrangement of the molecular or ionic structure of a substance, as distinct from a change in physical form or a nuclear reaction.

➡️ A reaction in which a substance undergoes a change and loses its identities to form a new product with completely different properties is known as chemical reaction.

For example :
