AP CHEM LAB: CHEMICAL BONDING ? POLAR OR NONPOLAR THEORY: ?Two atoms held together by the mutual attraction of each nucleus to valence shell electrons are said to be chemically bonded. The chemical bond can be represented by the overlap of the electron probability density map of an atomic orbital from each atom to form a molecular orbital capable of containing two electrons. Or said in English, a covalent bond can form. These electrons are shared between the respective atoms. However, the degree of sharing is not necessarily equal. The electronegativity of each atom can be used to approximate its attraction for the electrons and therefore the probability of finding the electrons closer to that nuclei.

Solubility Rules 1. All common salts of the Group 1 elements and ammonium ion are soluble. 2. All common acetates and nitrates are soluble. 3. All binary compounds of Group 17 elements (other than F) with metals are soluble except those of silver, mercury(I), and lead. 4. All sulfates are soluble except those of barium, strontium, lead, calcium, silver and mercury(I). 5. Except for those in Rule 1, carbonates, oxides, sulfides, and phosphates are insoluble. 6. Oxides and peroxides are always written in molecular form. 7. Gases are always written in molecular form. 8. The only strong bases are the hydroxides of Group I & II metals except beryllium. 9. The only strong binary acids are those of chlorine, bromine, and iodine.

Chemical Reactions and Stoichiometry Chapter 8 Balancing Chemical Reactions (Wednesday 1/5/11 P1,3,5 & Thursday 1/6/11 P2,4,6)? Indicators of a Chemical Reaction ? evidence of a chemical reaction Evolution of heat and light (simultaneously) Production of a gas (bubbles, odor change) Formation of a precipitate (solid, cloudy) Color change (not introduced by an outside source such as dye or ink) Characteristics of a Chemical Reaction ? the atoms in one or more reactant rearrange when bonds are broken and/or created to produce one or more new products with different properties than the reactants had before the reaction. Reactants - on the left? react to one another and/or their environment. Products ? on the right of the reaction ? produced/created from reactants.

Chapter 9 - Stoichiometry 9-1 Introduction to Stoichiometry Composition Stoichiometry - deals with mass relationships of elements in compounds Reaction Stoichiometry - Involves mass relationships between reactants and products in a chemical reaction I. Reaction Stoichiometry Problems A. Four problem Types, One Common Solution given mass ? given moles ? unknown moles ? unknown mass 1. Given and unknown quantities are in moles 2. Given is an amount in moles and the unknown is a mass (usually in grams) 3. Given is a mass in grams and the unknown is an amount in moles 4. Given is a mass in grams and the unknown is a mass in grams B. Mole Ratio 1. A conversion factor that relates the amounts in moles of any two substances involved in a chemical reaction
