Which option describes a substance that is a mixture?

• A. Solution
• B. Pure
• C. Element
• D. Mixture

Answer: (D)

A mixture is formed when two or more substances are combined without chemical bonds, so each part keeps its own properties and can be separated by physical means. This describes a substance that is a mixture because it means the components aren’t chemically bonded together. A mixture can be uniform throughout (a solution) or not uniform (a heterogeneous mixture). A solution is a specific type of mixture where a solute is dissolved in a solvent and the result appears uniform. A pure substance has a single composition and cannot be broken down by ordinary means; it can be an element (one kind of atom) or a compound (two or more kinds of atoms chemically bonded). Since the question asks for the term that describes a substance that is a mixture, the correct word is mixture.
