Solution
The correct option is D Mixture
The explanation for the correct option-
- A mixture is formed when atoms or molecules of the same or different particles combine with each other physically.
- For example - Air is a mixture of gases like Carbon dioxide, Nitrogen, Oxygen, etc; dust, and Water vapors.
- Since there is no chemical bond formation takes place during the formation of a mixture. Hence, a mixture can be separated into its constituents by using physical methods.
The explanation for incorrect options -
Options A and B are incorrect because an element: consists of only one kind of atom, and cannot be broken down into a simpler type of matter by either physical or chemical means.
Option C is incorrect because, in a compound, a chemical bond formation takes place between its constituents. Hence, it cannot be separated by any physical or mechanical means.
Hence, Option D is the correct answer.
