Which term describes a mixture consisting of two or more pure substances in which each substance retains its own properties?

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

Answer: (A)

When two or more pure substances are combined without forming new chemical bonds, you get a mixture, and each substance keeps its own properties. That means the components can be picked apart or separated by physical methods, and their amounts can vary. The description in the question fits this idea exactly: the substances stay identifiable and maintain their characteristics, even though they are together. In contrast, a compound is created when elements bond chemically in a fixed ratio, so the original elements lose their separate identities within the substance. An element is a pure substance consisting of only one type of atom. A solution is a homogeneous mixture where one substance (the solute) is dissolved in another (the solvent); while it’s a mixture, the defining feature here is the uniform distribution of components, rather than the preservation of their distinct identities.
