Yes, a chemical substance can separate microscopically into its constituent molecules or ions, particularly when subjected to processes like dissolution, diffusion, or chemical reactions. However, these components remain in a homogeneous phase at the microscopic level until they are influenced by external factors such as temperature, pressure, or concentration gradients. In some cases, such as in mixtures or solutions, the separation can be reversible, while in others, it may lead to the formation of new substances.

1) A colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium) in which the colloid is dispersed.2) A colloid is a substance microscopically dispersed evenly throughout another substance.

Physical change does not produce a new substance. Chemical change produces a new substanceIn a chemical change the atoms/molecules are chemically joined together so they are very hard to separate. were as they are easyer to separate in a physical change

when you separate a substance from a mixture, it's a physical change... Technically, you can get it back in the mixture.

A chemical property is the properties exhibited by a material in a chemical reaction. This gives a substance the ability to have a chemical identity and is also used in building chemical classifications. The properties can be used in identifying a substance that is unknown or to separate substances. The property also helps in providing information on the application of a substance.
In mineralogy, definite chemical composition refers to a characteristic that a substance must possess to meet the definition of a mineral. It is the narrow parameter of chemical compositions that a substance must have to be described as a particular mineral separate from other minerals.

You can purify a substance using methods such as filtration, distillation, crystallization, or chromatography. These techniques separate impurities from the desired substance based on different physical or chemical properties.
A substance is a chemical combination.
