Chapter 9: Chemical Quantities (~27%) I. Information from Chemical Equations - must follow the Law of Conservation of Mass (i.e. the reactions must be balanced) - coefficients of balanced chemical reactions can represent moles or molecules II. Chemical Equations and Stoichiometry A. Mole Mole Relationships - given moles of a reactant or product you need to be able to use the stoichiometric relationships given in the balanced chemical equation to convert to moles of any other reactant or product -pictorial representations of chemical reactions B. Mass Mole Mole Mass Relationships - given mass of a reactant or product you need to be able to use the stoichiometric relationships given in the balanced chemical equation to convert to the mass of any other reactant or product C. Limiting Reactants - Calculate Theoretical yields - Calculating the amounts of reactants that are left after a reaction is complete D. Percent Yield Chapter 15: Solutions (~27%) I. Solution Composition A. Properties of Solutions - solute vs. solvent - concentrated vs. dilute B. Quantitative Description of Solutions - mass % - molality - mole fraction - Molarity (aka concentration) - making a solution with a known molarity - molarity as a conversion factor - calculating the concentration of compounds - calculating the concentration of ions C. Dilution - what is going on when we dilute a solution (i.e. what is happening to the number of moles of solute?) - Calculations (M1V1=M2V2) II. Stoichiometry of Reactions in Solution A. B. Precipitation Reactions Titrations - equivalence point vs. endpoint Chapter 13: Gases (~20%) I. Properties of Gases A. Pressure II. The Ideal Gas Law A. Stoichimetry and the Ideal Gas Law B. Partial Pressures and Moles Fractions Chapter 11: Modern Atomic Theory (~20%) I. Interaction of Light and Matter A. II. Properties of Light - wavelength, frequency and energy of light - electromagnetic spectrum and energy of light - spectrum and energy of visible light Models of the Atom A. Bohr Model of the Atom - Emission and Absorption of Light by atoms and possible transitions of electrons B. Quantum Mechanical Model -types of orbitals and properties(i.e. energy, types, shapes, and numbers) -electron configurations and orbital diagrams for the elements -electron configurations of ions -categories of electrons (i.e. inner core electrons and valence electrons) III. Atomic Properties and the Periodic Table A. Atomic Size - Based on position, which atoms in a list will be the smallest and the largest B. Ionization Energy - Based on position, which atoms in a list will be have the smallest and the largest ionization energy C. Use Electron Configurations to Explain Why Ions Have a Certain Charge Part C not on test Chp 5: Nomenclature (~6 %)
