It is a pure substance composed of two or more elements that are cemically combined.
physical
Compounds can be decomposed by chemical reactions.
what do you mean
Mixtures can be separated by physical methods.
Compounds can be separated into their constituent elements only by a decomposition reaction.
Fractional distillation
by weight and by solubility
No, compounds cannot be separated by physical methods. Because of their chemical bonds, they can only be separated by chemical methods.
Separated compounds refer to the products obtained after a mixture has been separated by physical or chemical means. This process involves isolating individual substances from a mixture for further analysis or use. Separation techniques include distillation, filtration, chromatography, and extraction.
No, a compound doesn't need to be colored to be separated by chromatography. There are plenty of detectors that can be used outside of the visible spectrum, and in fact don't even use spectroscopic methods, such as Electron Capture detection (ECD).
the ease with which the elements can be separated.
Phosphate can be separated from its compounds by various methods such as precipitation using calcium or magnesium ions, ion exchange using resins, or filtration through membranes. These methods help to isolate and recover phosphate from its compounds for further processing or reuse.
