Because of the charges of particles and different atomic weights of both elements and compounds.
A magnet. The magnet will attract the magnetic material to it and so separate the magnetic material from the mixture.
A heterogeneous mixture is a type of mixture that has multiple components. These components are separate physically in this kind of mixture.
A mixture in which two or more substances are not mixed evenly is called a heterogeneous mixture. In this type of mixture, the individual components retain their distinct properties and can often be visually distinguished from one another. Examples include salad, sand and salt, or oil and water, where the different substances remain separate.
Foil does not separate a mixture of chalk powder, sugar, and water because the physical properties of these substances are not effectively separated by the foil. Chalk powder and sugar are both soluble in water, meaning they dissolve and form a homogenous solution. The foil is not able to selectively separate the components of the mixture based on their solubility or other physical properties. To separate these substances effectively, techniques such as filtration or evaporation would be more appropriate.
Any particular isolated sample of a mixture has a definite chemical composition, but the general idea of a mixture, even of the same materials, implies variability in possible chemical composition.
relative density
a mixture
It is true because the solution is clean and transparent. It is not possible to separate the constituents by physical means.
Density allows a mixture to be separated by centrifugation.
A heterogeneous mixture is made of different substances that remain physically separate.
Well, you have to be very specific about this question. Substances can separate in a compound mixture, such as chex mix, by pulling the stuff right out. Other stuff, maybe not.
One common method is to use filtration to separate insoluble substances from soluble substances. The mixture is passed through a filter that catches the insoluble substances, while allowing the soluble substances to pass through. Another method could be to use techniques such as centrifugation or precipitation to separate the insoluble substances from the soluble ones in the mixture.
A magnet. The magnet will attract the magnetic material to it and so separate the magnetic material from the mixture.
In chemistry, a mixture is a material system of two or more different substances which are mixed but are not combined chemically. A mixture is the physical combination of two or more substances on which the identities are retained and are mixed in the form of solutions, suspensions, and colloids.
The physical properties of substances can be used a a technique! :)
