what kind of heterogeneous mixture when left undisturbed settle down for a long time?

Sagot :

Answer:

Suspension

Suspension is a heterogeneous mixture. The particles of a suspension can be seen by the naked eye. The particles of a suspension scatter a beam of light passing through it and make its path visible. The solute particles settle down when a suspension is left undisturbed, that is, a suspension is unstable.
