Which term describes a mixture with visibly different parts or phases?

• A. Mixture
• B. Homogeneous mixture
• C. Heterogeneous mixture
• D. Compound

Answer: (C)

A heterogeneous mixture shows visibly different parts or phases because its components are not evenly distributed. You can usually see distinct materials within it, like a salad with varying ingredients, a rock with different minerals, or muddy water where particles stand out. This is different from a homogeneous mixture, which looks uniform throughout, with the same composition everywhere. A compound is a single substance formed when elements chemically bond in fixed amounts, so its components aren’t observed as separate parts by simple mixing. So, a mixture with clearly different parts is a heterogeneous mixture.
