here is ur answer....
Compounds refer to substances that are made up of two or more elements that are chemically bonded together. Furthermore, they are pure substances and not mixtures.
Example: Common salt (NaCl)
Sodium is a highly reactive element. It reacts with chlorine which is a yellow-green poisonous gas. They combine to form sodium chloride or common salt.
Mixtures are made up of two or more materials that are not chemically bonded or that do not undergo any chemical reaction. Furthermore, they are mixed physically and are impure substances.
Example: Ocean water
It is a mixture of water and salts. It can be called a water solution which contains several salts.
