coffee grounds, water, oil, and salt. We have access to all of the high school lab equipment, but were given no directions on how to separate these substances. I know how to separate salt from water by evaporation, but I have no clue how to separate any of the others.
when you separate a substance from a mixture, it's a physical change... Technically, you can get it back in the mixture.
Transpiration
The particle that separates a substance from a mixture is called a filter. This can be a physical barrier, such as a sieve or filter paper, that allows smaller particles to pass through while trapping the larger substance particles to separate them from the mixture.
a mixture is the anwser for apex
Chromatography was originally designed to separate plant pigments, particularly chlorophyll, from a mixture.
No, black pepper is not a pure substance. Instead, black pepper is what we call a mixture substance. However, salt is a pure substance.
An element - substance - NOT a mixture.
When one substance is insoluble in another, they form a heterogeneous mixture where the insoluble substance remains separate and distinct within the mixture. This can result in the formation of phases such as suspensions or precipitates, depending on the nature of the substances involved.
a mixture is not a substance
A colloid is an example of a mixture. Specifically, colloids are mixtures in which the components do not separate. Mixtures in which the components do separate are known as suspensions.
If the mixture is a mixture of solids and if one of constituent is a ferromagnetic substance, a magnet can be used to separate the magnetic and non-magnetic substances. If one of the constituent is a sublimate, sublimation can be used. If the mixture is a mixture of solids and liquids, decantation, filtration and distillation can be used. If the mixture is a mixture of liquids, fractional distillation can be used to separate the different constituents taking advantage of the difference in boiling points of the different constituents.
