mixtures by checking all of the terms that apply. smoke homogeneous heterogeneous solution colloid suspension done

Explanation:

Smoke is a mixture of solid particles (ash, soot etc.) dispersed in air. It has a non - uniform composition (heterogeneous). It is a colloid as the particle size is between 1 - 1000 nm and shows the Tyndall effect. It is not a homogeneous solution or a suspension (particles don't settle out quickly like in a suspension).

Answer:

heterogeneous, colloid
