↓Properties of Mixtures↓ Mixtures can be physically separated/ Substances in a mixture retain their identity __-

Esther grossman presents ms. Manhart there were a few problems such as my attempt at a graph and the video is misplaced but all in all it is together__

Section 1 (Lars) An __Element__ is a simple, pure substance that cannot be changed into a simpler substance. You can identify a substance by its unique charicteristic properties such as color, melting point, boiling point, density, conducts electricity, rectivity with acid, taste, ect. Mainly physical and Chemical properties. There are three elements. Metals, non-metals, and metalloids. Metals are malleable (can be shaped without breaking) and can cunduct electricity. Non metals are poor conductors of electricity and brittle (not malleable). Metalloids are ductile (can be flatened into thin sheets) and can cunduct thermal energy. Elements are the alphabet of science and are found on the periodic table. They are made up of only one atom. A __Pure Substance__ is made up with one kind of material with definite properties. They cannot be simplified so they are in their simplest form. Can be a compound or an element. It is only one substance. Section 2 A __Compound__ is a pure substance made of two or more elements that are chemically combined (Science text 86). Compounds are different than from mixtures because mixtures are not chemically combined and they need a certain definite ratio. Compounds are also different from elements because th compounds can be broken down chemically and are made of 2 or more substances. Elements make up compounds but mixtures are made up of two or more substances. Furthermore the compounds are not on the periodic table were elements are.(gino) Section 3 A __Mixture__ is a combination of two or more substances that are not chemically combined such as a pizza. They retain there I.D. and you may see thier components or you may not. There are types of mixture __Solute__- The dissolved substance __Solvent__-The substance which the solute is dossolved __Solubility__The amount of solvent needed to make a saturated solution using a given amount of solvent at a certain temperature.
