Give three examples of mixtures, and tell whether each one is homogeneous or heterogeneous. Give three examples of compounds.

A mixture is a substance formed by combining two or more elements in a way that involves no chemical reactions. The elements in a mixture can be easily separated using physical means.

There are two types of mixtures:

Homogeneous mixtures: these are mixtures in which you cannot see the particles of the elements forming it. Examples of homogeneous mixtures: lemonade and coffee.

Heterogeneous mixtures: these are mixtures in which you can see the particles of the elements forming the mixture. Examples of heterogeneous mixtures: oil and water, cereal and milk as well as sand in water.

On the other hand, a compound is a substance formed by the combination of two or more atoms by a chemical reaction. The elements in a compound cannot be separated by physical methods. Examples of compounds: ammonia, acetic acid and methane.
