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
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.
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.
A mixture is the opposite of a pure substance. A mixture is made up of two or more pure substances that are physically combined and can be separated by physical means.
Pure substances have a fixed chemical composition and consist of only one type of element or compound. They cannot be separated by physical means and have consistent physical and chemical properties. Examples include elements like gold and compounds like water.
