Answer:
-Its components are visible- heterogeneous mixture.
An heterogeneous mixture has visible boundaries of separation between the various constituents. It has two or more visible phases. It has more than one kind of component visible to the eye.
-It may be mistaken for a pure substance- homogeneous mixture.
A pure substance isn't mixing with anything else but all mixtures consist of o or more substances, however as homogeneous mixtures don´t have visible components, we can be mistaken for a pure substance.
-It can be separated using distillation- homogeneous mixture
This process can separate a variety of mixtures with different boiling points. Distillation is used to separate mixtures that are homogeneous.
-Example:
homogeneous mixture: A solution of sodium chloride in water.
