all mixtures can be separated into pure substances by physical methods. A mixture is a substance which its constituents retain their individual properties. examples of mixtures are sea water which contains salt,water,bacteria etc
yes it can be separated by applying reverse pressure method but only to some mixtures it have its limitations.
The substances in a(n) mixture can be physically separated from one another.

No, just mentally
This substance is a mixture.

Elements are pure substances that can not be separated into simpler substances by physically or chemical means.Compounds are pure substances composed of two or more elements that have been chemically combined.Mixtures are a combination of two or more substances that are not chemically combined.

Mixtures can be separated by physical means, whereas pure substances cannot. Also, mixtures are composed of multiple substances, while pure substances are, as the name implies, composed of only one substance.

They are aqueous solutions of various compounds in water, so they consist of many separate pure substances. Many of these can be separated by simple physical means (filtering, evaporating, centrifuge).
cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition
A heterogeneous mixture can be separated into its components by physical means. On the other hand, compounds cannot be separated into their component elements expect by chemical means. Compounds are pure substances whereas mixtures are not.
1. A mixture contain two or more substances. 2. A mixture can be separated in components by physical procedures.
No. This is because a pure substance is a compound (or element) and can only be separated chemically but mixtures can be separated physically. P.S. This answer was written by a 14 year old from Dearborn Michigan
Pure substances are either elements or compounds. They cannot be separated by physical means.
