Which type of mixture has components that are not evenly distributed, with different samples having different properties?

• A. Homogeneous mixture.
• B. Heterogeneous mixture.
• C. Colloid.
• D. Solution.

Answer: (B)

The key idea is how uniformly the components are distributed. A heterogeneous mixture has parts that are not spread evenly, so different samples can show different properties, like a bowl of mixed nuts where some scoops have more almonds and others more peanuts, or soil with varying amounts of sand, clay, and organic matter. That nonuniformity is what makes each sample feel and look different. In a homogeneous mixture or a solution, the composition is uniform throughout, so any sample taken would have the same properties. A colloid is a mixed system with dispersed particles that can appear uniform at a glance, but the distinction here is about not having a consistent distribution across samples, which is most characteristic of a heterogeneous mixture. Therefore, the described type is a heterogeneous mixture.
