Question

which statements are true of heterogeneous mixtures? check all that apply. they settle out. they exhibit the tyndall effect. their solutes and solvents appear as one. they exhibit brownian motion. they are evenly distributed mixtures.

Explanation:

Heterogeneous mixtures have non - uniform composition. The heavier components can settle out over time. Also, since they have larger particles, they can exhibit the Tyndall effect (scattering of light by particles). Solutes and solvents in heterogeneous mixtures are distinguishable and not evenly distributed. Brownian motion is more characteristic of colloids and solutions with very small particles rather than typical heterogeneous mixtures.

Answer:

They settle out.
They exhibit the Tyndall effect.
