Which statement describes a homogeneous mixture?

• A. A mixture in which the substances are randomly distributed and look different at different spots.
• B. A heterogeneous mixture with visibly different parts.
• C. A homogeneous mixture is a uniform mixture of two or more substances that looks like one substance.
• D. A pure substance with a single component.

Answer: (C)

In a homogeneous mixture, the substances are evenly distributed so the mixture looks like one substance all the way through. That uniform mix means you can’t tell the different parts just by looking at it. The statement describes this idea exactly: it’s a uniform blend of two or more substances that appears as one substance.

Think of sugar dissolved in water or air you breathe—the parts are mixed so well that you don’t see separate pieces. That’s why this option is the best choice.

Other descriptions point to different ideas: a mixture where you can see distinct parts is heterogeneous, or a pure substance has only one component and isn’t a mixture at all.
