Particle size, solubility and magnetism. The iron filings can be separated with a magnet, the salt by disolving in water, and the remaining sand and gravel separated by simple screening.
you an use a magnet to get the iron fillings out
To separate a mixture of iron fillings and sand in a plastic bowl, you can use a magnet. Simply move the magnet over the mixture; the iron fillings will be attracted to the magnet while the sand will remain in the bowl. After collecting the iron fillings on the magnet, wipe them off into a separate container, leaving the sand behind. This method effectively separates the two components based on their magnetic properties.
When substances combine and retain their own properties, the result is a mixture.
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.
A mixture cannot be separated with chemical change because a mixture is two or more substances which will retain their physical properties when combined. Mixtures are separated by physical means like filters, sifting, chromatography, centrifuge, electrophoresis and magnetic attraction depending on what the mixture is composed of.
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.
The physical properties of substances can be used a a technique! :)
Use a magnet.

You can use a magnet to separate the iron fillings from the sulfur powder. The iron fillings will be attracted to the magnet, allowing you to easily separate them from the sulfur powder.
Place the mixture in water. You recover the iron once the salt dissolves. Then allow the water salt mixture to dry and allow salt crystals to reform.
One method to separate iron fillings from sand is by using a magnet. The iron fillings are attracted to the magnet and can be easily separated from the sand.
Filtration takes advantage of differences in particle size to separate substances from a mixture, while distillation uses differences in boiling points to separate substances based on their volatility. Both processes rely on physical properties of the substances being separated to achieve purification.
Iron fillings can be separated from sulfur powder by using a magnet. When a magnet is brought close to the mixture, the iron fillings will be attracted to the magnet and can be easily pulled out, leaving behind the sulfur powder. This process takes advantage of the magnetic properties of iron to separate it from non-magnetic substances like sulfur.
Industries use physical properties like boiling point or solubility to separate substances through techniques like distillation, filtration, and chromatography. These methods capitalize on the differences in physical properties between the substances to effectively separate them at a molecular level.
The iron fillings would be attracted to the magnet due to their magnetic properties, separating them from the sulfur powder. This phenomenon is known as magnetic separation and is commonly used to isolate magnetic materials from non-magnetic substances in a mixture.
When substances combine and retain their own properties, the result is a mixture.
