- 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 else can I help you with?
What is true of all mixtures?
All mixtures are a combination of two or more substances that are physically combined, not chemically bonded. Mixtures can be separated by physical means such as filtration or distillation. The properties of the components in a mixture remain unchanged.
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 mixtures defined as heterogeneous?
No, not all mixtures are classified as heterogeneous. Mixtures can be either heterogeneous or homogeneous. Heterogeneous mixtures have visibly different components, while homogeneous mixtures have uniform composition throughout.
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.
All mixtures are also solutions true or false?
False. While all solutions are mixtures, not all mixtures are solutions. A solution is a homogeneous mixture where the components are evenly distributed at a molecular level, while a mixture can be heterogeneous with uneven distribution of components.
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

No, not all mixtures are classified as heterogeneous. Mixtures can be either heterogeneous or homogeneous. Heterogeneous mixtures have visibly different components, while homogeneous mixtures have uniform composition throughout.
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.

False. While all solutions are mixtures, not all mixtures are solutions. A solution is a homogeneous mixture where the components are evenly distributed at a molecular level, while a mixture can be heterogeneous with uneven distribution of components.
Differences between coumpounds elements and mixtures?
compounds are 2 or more elements bonded together and the bonds cannot be broken without chemical reactions. mixtures can be easily seperated. elements cannot be broken down at all. How to tell if its a gas: If you stick your tongue on it, and it burns, its a gas. It may sound really weird, but it's amazingly true.
What do all mixtures have?
All mixtures have two or more components which doesn't react between them.
