Mixtures: can be separated by physical means
Substance is a vague term which could be a mixture but may not be.
Mixtures and substances both consist of matter, but they differ in composition and properties. A substance has a uniform and definite composition, meaning it has consistent properties throughout, like water or sodium chloride. In contrast, mixtures are combinations of two or more substances that retain their individual properties and can vary in composition, such as air or saltwater. Despite these differences, both can be found in various forms and states of matter.
A substance is considered a mineral when it is a solid and has a defined chemical composition, crystalline structure, and is naturally occurring. Minerals are inorganic, meaning they are not derived from living organisms. They also typically exhibit specific physical properties, such as hardness and luster. Together, these characteristics distinguish minerals from other types of materials.
heterogenous mixtures
Not necessarily. A solution is a kind of mixture but not all mixtures are solutions.
Mixtures: can be separated by physical means
Mixtures are made up of two or more substances physically combined, but not chemically bonded. Components of a mixture can be separated using physical methods. Mixtures do not have a fixed composition or properties, as they can vary depending on the amounts of each substance present.
No they are mixtures
what is mixtures
nothing
The two main branches are pure substances and mixtures.
no
if a substance is a mixture then it is heterogeneous.
Mixtures may be homogeneous or heterogeneous.Mixtures may be liquids, solids, gaseous.
Substances together, but can be separated.
Mixtures are formed from substances (compounds).
