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.
