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.
heterogenous mixtures
Not necessarily. A solution is a kind of mixture but not all mixtures are solutions.
Definite chemical makeup refers to the specific composition of a substance, characterized by a consistent ratio of elements and compounds that define its identity. This concept is fundamental in chemistry, as it distinguishes pure substances from mixtures. For example, water (H₂O) always consists of two hydrogen atoms and one oxygen atom, maintaining the same chemical properties regardless of its source. Understanding a substance's definite chemical makeup is crucial for predicting its behavior and interactions in chemical reactions.
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).
