Chemistry II Fall Final Guidelines

Chem II Fall Final Specifics • 50 Multiple Choice Questions • All questions weighted equally • Will be given Periodic Table with most equations and constants, as well as a solubility table and activity series • Alllowed Cheat Sheet: 8 ½ x 11 sheet , front and back – Must be handwritten – Cannot be photocopied – May include anything, including example problems

Cheat Sheet Ideas • Significant Figure Rules – Counting and Calculations • Basic Metric Conversions/Prefixes • Nomenclature Rules – – Nomenclature Flow Chart Roman Numerals (and when to use them) Greek Prefixes (and when to use them) Acid Nomenclature Rules • Reaction Types (S, D, SR, DR, Comb) • How to use activity series/solubility table – Predicting Single/Double Replacement Reactions • Mole Island Diagram (most definitely!) – Procedure for Limiting Reactant/%Yield problems

Cheat Sheet Ideas • Sign conventions for q and w • Heating Curve of Water – Steps 2 and 4 (k. J), Steps 1, 3, and 5 (J) – Make ΔH (-) if going down curve • Nuclear decay particles • Example Problems Ideas SF Calculations Conversions Nomenclature (important for Word Equations!) fixed/variable charge ionic, covalent, acids Name → Formula and Formula → Name

Cheat Sheet Ideas • Example Problems, con’t Balancing Equations Predicting Products of SR, DR, and Comb. Rxns Writing Complete and Net Ionic Equations Stoichiometry Calculations Limiting Reactants/Excess Reactants % Yield/% Error Internal Energy Heating Curve Calculations (1 -5 steps) Calorimetry (q 1 = -q 2)

Cheat Sheet Ideas • Example Problems, con’t Half-life problems Transmutation reactions Nuclear definitions (i. e. fission v. fusion) Complete atomic designation
