Question

Each substance in a mixture is called a ______ of the mixture.

Answer 1

1. Each substance when they are combined/mixed in any proportion forms an impure substance called a Mixture and each constituent substance of such mixture is called a component of that mixture.
2. Components of a mixture retain their properties in the mixture.
3. Example: Air is a mixture of different gases like dinitrogen( ${\mathrm{N}}_2$), Oxygen (${\mathrm{O}}_2$), water vapor (${\mathrm{H}}_2\mathrm{O}$), Carbon dioxide (${\mathrm{CO}}_2$), etc. These gases are called the component of Air.

Thus each substance in a mixture is called the component of the mixture.
