How is matter
classified?
Matter is classified by either pure substances or mixtures. Pure substance is separated by elements or compound. Also mixtures are separated by heterogeneous or homogeneous. What is the difference between physical can chemical properties? Physical properties can be observed and measured, without changing it into a different substance. Also you can see, smell, taste, and feel physical properties. Physical properties are used to describe that physical object. On the other hand, chemical properties can not be smell, taste, or feel. A chemical property is a property of a substance that being observed during its reaction, where its substance will be change. |
What is the difference
between substances, atoms, elements, compounds and mixtures
(heterogeneous, homogeneous and solutions)?
Substances - Are type or kind of matter, with very specific properties. Also pure substance is a particle that can not be broken down. There is only one set of molecules. Atoms - Are like simple building blocks of matter that make up objects. Even solid, liquid, and gas is make up atoms. Elements - A substance that is made entirely by one type of atom. Compounds - A molecule that is made of atom, from two or more elements. Mixtures - Are made of one or more different substances that are mix up together. But they are not chemically combined, this mean that the substances in mixtures are hard to separate. Heterogeneous - Make up different substances that are able to be separate. Heterogeneous are unevenly mix, that can be easily separate. Homogeneous - Any mixtures that can not separate different substances. Homogeneous is very evenly mixed; you can not see the different parts. Solutions - A mixture that appear or show to only be a single substance. During a solution, there are two substances that are evenly mixed. One is called solute and the other solvent. Solute is the substance that is dissolved. Solvent is the one that is doing the dissolving. |
