Question

milk is a heterogeneous mixture that contains different types of particles in different phases. due to the sizes of the particles in milk and the way they are dispersed, the particles do not easily settle out. they also cannot easily be filtered out.

therefore, milk is best described as a
dropdown options: solution, suspension, compound, colloid

Explanation:

1. Recall the definitions: A solution has particles too small to scatter light or be filtered. A suspension has large particles that settle or can be filtered. A compound is a pure substance, not a mixture. A colloid has particles (1 - 1000 nm) that don't settle easily and can't be filtered easily, matching milk's properties (particles don't settle/filter easily, heterogeneous mixture with dispersed particles). So milk is a colloid.

Answer:

colloid
