Question

a homogenous mixture is best described as: a a pure element b a solid and a liquid mixed together c a mixture that looks the same throughout d a mixture with visibly different paths

Explanation:

• Option A: A pure element is a single substance, not a mixture, so A is incorrect.
• Option B: A solid and liquid mixed can be heterogeneous (like sand in water) or homogeneous (like salt in water), but this doesn't define a homogeneous mixture. So B is incorrect.
• Option C: A homogeneous mixture has a uniform composition, meaning it looks the same throughout (e.g., salt water, air). This matches the definition.
• Option D: A mixture with visibly different parts is a heterogeneous mixture, not homogeneous. So D is incorrect.

Answer:

C. A mixture that looks the same throughout
