I plan to review chemistry units covered in a chemistry honors course They are listed below: Matter & Measurement Significant figures, unit conversations Types of matter (elements, compounds, mixtures) Memorize symbols and names of common elements (Properties of substances: density, melting point, and boiling point Atoms, Molecules, and Ions Atomic theory: history of discovery of electron, proton, & neutron Determining the number of protons, neutrons, & electrons for atoms and ions Molar mass of molecules, concept of mole and molarity Chemical Formulas and Stoichiometry Percent composition: from formula to percent and vice-versa Nomenclature: memorize polyatomic ions and charges (handout) Writing and balancing equations: from names to formulas to reactions Mass relations: Stoichiometry Mole-mole relations, mole-mass relations, mass-mass relations Limiting reactant problems and theoretical yield Thermochemistry Calorimetry, Definitions: endothermic & exothermic, reaction enthalpy Thermochemical equations; Laws of Thermochemistry Stoichiometric relations in thermochemistry Hess' Law and heats of formation Behavior of Gases Boyle's Law, Charles' Law, Ideal Gas Law, Dalton's Law, Graham's Law Stoichiometry using gas laws Electronic Structure History and Bohr model Quantum numbers: definition of each number, drawings of orbitals Pauli Exclusion Principle Electron configurations: atoms and ions Orbital diagrams and Hund's Rule, (exceptions: Cr and Cu) Periodic Law Atomic radii, ionization energy, including exceptions Electron affinity, metallic character Covalent Bonding Lewis structures: simple molecules and polyatomic ions, resonance forms Exceptions to the octet rule: B and Be compounds, odd-electron species Bond energies, bond lengths, bond polarity, polarity in molecules Molecular Structure Hybridization: sp, sp2, sp3, expanded octets: spzd, sp3d, sp3d2 Molecular polarity, sigma and pi bonds Liquids and Solids Intermolecular forces of attraction; dispersion, dipole, and hydrogen bonding Types of solids: covalent network, ionic, molecular, and metallic Acid-Base Equilibria Titration curve problems (mixtures) Hydrolysis of salt solutions: determine pH Electrochemistry Oxidation - Reduction; balancing redox equation Galvanic cells and electrolysis (faraday) I would be happy to add more per request. Be ready to answer questions in zoom sessions. This session is specifically for those who are currently struggling in chemistry or want to get ahead with the curriculum by preparing for a chemistry course they will take in the near future, or prepare for content they will learn in the future in their current chemistry class to be better prepared.
