Can an element be separated by physical methods?
There are several ways in which elements can be separated by physical methods. Centrifuge If you grind an ore to sufficient fineness, you can use a centrifuge to separate an element based on its specific gravity. Panning is a more primitive version of this basic method. Gaseous Diffusion You can also heat an ore to the temperature at which a particular element becomes gaseous and separate it out.
No. A pure substance is a chemical that is only composed of one component. It cannot be separated by any method, chemical or physical. Physical separations are methods of separating two compounds by their physical properties. These methods include but are not limited to filtration, distillation, decanting, centrifugation, and chromatography. It is possible that you could have two chemicals mixed together that could not be separated by any of these methods.
What is a pure substance that cannot be separated into simpler substances by physical or chemical means?
What is a pure substance that cannot be seperated into simpler substances by physical and chemical means?
A mixture is a combination of different molecules that can be separated using physical methods, like filtrata combination of different molecules that can only be separated using chemical means sy to separate and this can be done just by letting them settle out into their layers. This is a physical process and therefore the combination of oil and water is a mixture.
