Notes ? Matter Describing Matter Definition - Anything that has mass and takes up space. Matter can be in three states (plasma is another state but exists at high energy that we will not deal with) Solid ? definite shape, definite volume, particles packed closely together Liquid ? indefinite shape, definite volume, particles can flow easily Gas/Vapor ? indefinite shape, indefinite volume, particles are spaced far apart Similar terms but not interchangeable Gases exist as gases at room temperature Vapors are in a gaseous state but generally exist as solids or liquids Characteristic/Physical Properties Physical Properties ? characteristics that are observed but never change for a substance Boiling point (condensation) - temperature at which a liquid turns to a vapor

Notes - Double Replacement Products TERMS Soluble - substances that can be dissolved in water. Insoluble - substances that cannot be dissolved in water. Precipitate - a substance that falls out of solution when it is one of the products of a reaction. Precipitates are insoluble in water. The symbol for a precipitate is ? and would be a solid (s) for the state of matter RULES In a double replacement reaction the metal parts of each reactant switch places. Write down the new products. Look up the new products in a table of solubilities. If a product is listed as being insoluble, this product is a precipitate. Write the symbol for a precipitate, ? , after any product that is listed in the table of solubilities as being insoluble.

Notes ? chemical nomenclature/naming compounds Ch 6.3-6.6 Monoatomic noble gases These are the noble gases. These are elements that exist in nature as isolated elements. They do not combine with other elements to form compounds (as far as this class is concerned). Diatomic Molecules Diatomic elements or molecules ? compounds made of two atoms of the same element I2 Br2 Cl2 F2 O2 N2 H2 Binary compounds made of at least 2 different elements Three types Type 1 ? metals and nonmetals Type 2 ? metals and nonmetals Type 3 ? nonmetals and nonmetals Type 1 Ionic compounds that contain a metal and nonmetal Metal forms one cation (from group 1, 2, 13) the nonmetal forms the anion Write the Cation first and the anion second, put an ?-ide? on the end of the nonmetal

REACTANTS ?PRODUCTS 1.? Starting substances (reactants) becomes new substances (products). 2. Bonds are broken and new bonds are formed, but atoms are not created or destroyed (just rearranged). Law of Conservation of Mass PRODUCTS REACTANTS SENTENCE EQUATION Iron reacts with oxygen to produce rust WORD EQUATION Iron + oxygen ? iron (III) oxide SKELETON EQUATION Fe + O2 ?Fe2O3 These DO NOT indicate the relative amounts of the reactants and products. BALANCED EQUATION most correct equation includes the physical states of each substance uses coefficients 4Fe(s) + 3O2(g)?2 Fe2O3(s) Learn chart of symbols on page 206 in text.
