false
False. Pure substances cannot be separated by physical means. They are chemically uniform and do not contain any impurities that can be separated through physical methods like filtration or distillation.
Mixtures, such as saltwater and trail mix, are physical combinations of different pure substances that can be separated into their original components by physical means like filtration, distillation, or evaporation.
The characteristics of pure substances are:fixed melting pointfixed boiling pointsfixed valencyfixed densitystability
Mixtures are more common in the world compared to pure substances. Mixtures are combinations of two or more substances that can be physically separated, whereas pure substances are composed of only one type of substance and cannot be separated by physical means.
The two types of substances are pure substances and mixtures. Pure substances are made of only one type of particle and cannot be separated into other substances by physical means, while mixtures are made of two or more different substances that are physically combined and can be separated by physical means.

No, just mentally
If a substance can be physically separated into its components, it is a mixture, not a pure substance. A pure substance consists of only one type of particle and cannot be separated into other substances by physical means.
Substances are pure and have a specific chemical composition, while mixtures are a combination of two or more substances that can be separated physically. Substances have specific properties that do not change, while mixtures can have variable properties depending on the ratio of the components.
The opposite of a pure substance is a mixture.
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
