Question

What is an example of an heterogeneous mixture?

Answer 1

Milk

Explanation:

Milk is heterogenous meaning made of different parts.
The mixture of milk has distinct parts that do not form even temporary bonds or electro static attractions as in a solution.

Milk is made of water, calcium, various other minerals such as magnesium, and fat molecules. The fat molecules are suspended in the mixture, the random motion of the molecules ( Brownian motion) keeps the fat molecules suspended.

Cursing the milk allows the fat molecules ( cream) to rise to the surface, upsetting the molecular motion of the suspension allowing the fat molecules to leave the mixture.
