- Mixtures consist of more than one type of pure substance. Therefore, mixtures have different kinds of particles present. The particles can be either molecules, atoms or ions.
- Mixtures can have different proportions of substances present. The mixture can have different 'recipes' or colors.
- Mixtures do not have a definite boiling point, bp. The bp will change as the mixture continues to boil. Compared to a pure substance where the boiling point has a particular temperature and the temperature stays the same as it boils
- Mixtures do not have a definite freezing or melting point, mp. The mp will change as the mixture starts to melt whereas a pure substance will stay the same temperature until it has all melted.
- Mixtures can be separated into substances that have different properties from the mixture. Whereas a pure substance can not be separated although if enough energy is applied it can decompose into its constituent elements.
- Mixtures do not have a chemical formula whereas a pure substance does.
Examples of mixtures: glass, sea water, milk, fruit juice, brass, paint, most of the water that lies around, steel (metal mixtures are called alloys), soap, most of the stuff around us
Examples of pure substances: water, H2O; table salt, NaCl; sugar, C12H22O11; plastic food wrap if it is not colored, (C2H2)n repeating units; petrol/gasoline/octane, C8H18, although the petrol that we buy is a mixture of coloring agents, smelling agents and other hydrocarbons.

What Are The Three Things Mixtures Have In Common?
1. All mixtures can be easily separated using an ordinary physical method 2. The constituents of mixtures are nt combined in a definite ratio 3. Constituents of mixtures retain their properties
Are all solutions mixture's and all mixtures solutions?
No. A solution is a homogeneous mixture -- in which the components have the same composition throughout, down to the molecular level. Salt water and air are examples of solutions. Many mixtures are not homogenous. Rocks and oil-based salad dressing are examples of mixtures that are not solutions.<br>
Is all mixtures are solutions true or false?
False. As an example wet sand is a mixture of water and sand, but it is not a solution as the two substances remain as distinct phases.
Are all mixtures defined as heterogeneous?
all mixtures are defined as heterogeneous
What is a characteristic of all mixtures?
their composition can be varied
Is all mixtures are solutions true or false and why?
false all solutions are mixtures but not all mixtures are solutions
Are all mixtures can be separated by physical processes.?
FALSE It is true the above answer is wrong

Is grass a compound or a mixture?
Grass is a mixture. In these terms, all living things are mixtures.
Is it true that the parts of a mixture can be separated?
But of course. If you shake up soil and water to make a mixture you can separate it out by filtering it. I would imagine that you could separate all mixtures.
Is a pony a heterogeneous or a homogeneous mixture?
Ponies, and in fact all living things, are heterogeneous mixtures.
Are all solutions mixture's and all mixtures solutions?
No. A solution is a homogeneous mixture -- in which the components have the same composition throughout, down to the molecular level. Salt water and air are examples of solutions. Many mixtures are not homogenous. Rocks and oil-based salad dressing are examples of mixtures that are not solutions.<br>
Are all solution mixtures?
Yes, all solutions are by definition mixtures.
Are all mixtures solutions and why?
No mixtures are solvents
Is all mixtures are solutions true or false?
False. As an example wet sand is a mixture of water and sand, but it is not a solution as the two substances remain as distinct phases.

Are all mixtures are solution?
Yes, all solutions are by definition mixtures.
