13. what is the difference between a solution and a heterogeneous mixture? give an example of each. (4 points)

The macroscopic appearance is different.

Explanation:

The two (solution) and heterogeneous mixture are actually mixtures. These are made up of one of two pure substances in gaseous and liquid phases.

However, the difference lies in the macroscopic level of the particles.

A heterogeneous mixture is made of different substances. For example, when powdered milk is added to water, the mixture is a white substance, or colloidal mixture. The mixture is a heterogeneous in the sense that is all liquid; however, the mixture is not the same color as water. Thus, there is not complete dissolution.  

A solution is the same throughout. An example is dissolving sugar into water. The solution is colorless throughout. The difference is that the sugar and water have formed a solution whose properties are not visible to the naked eye.

you need to have a picture of the atom that way we can answer it
