What is the importance and applications of mixtures give examples?
In general, almost everything undergoes the process of mixture. For example the air we breathe which is a mixture of oxygen, nitrogen, and other gasses. In science, mixture is used to combine elements, chemicals and etc. to create more complex substances (or outcomes) that will be used or processed.
Why is separation of mixtures important to our everyday life?
A mixture is actually made up of pure substances only. But they get mixed with each other in a mixture. Sometimes the individual pure substances are more important than the mixture. Thus, separation of substances is necessary to obtain pure substances for domestic purposes, industrial purposes and research work.

What are the properties of pure substances and mixtures?
Differences Between Pure Substances and Mixtures
| Pure Substances | Mixtures |
|---|---|
| Constant physical and chemical properties. | Mixtures have varying physical and chemical properties. |
| Pure substances are made up of a single element. | A mixture is a combination of two substances or elements. |
Is coffee a substance or mixture?
Coffee is a solution, not a compound or mixture, as it includes a solute that dissolves into a solvent. Compounds must be bonded chemically, and mixtures have visibly separate parts. Coffee can also be considered a mixture since it involves two mixed substances, but this is too vague.
