The scientific method

Atomic structure and nuclear reactions

Nomenclature/writing formulas for acids, ionic and molecular compounds, hydrates, and polyatomic ions

Predicting products/balancing equations, including:

• acid/base, double replacement, decomposition, synthesis, single replacement, and hydrocarbon combustion rxns

• REDOX equations!!!!! (with half reactions), also determining if a reaction is a redox reaction or not

• the activity series for metals and halogens

Determine net ionic equations (thus, know your solubility rules)

Stoichiometry, including moles, molarity, limiting reagent, and Avogadro’s number (note: this may involve gas

stoichiometry, too!)

Lewis dot/VSEPR shapes (including formal charge, hybridization, resonance, and bond types (vs))

Heat of formation reactions

Three methods to determine ∆H (Hess’s Law, calorimetry, bond dissociation energies)

Types of electromagnetic radiation: relative ranking with respect to energy, , and , as well as understanding how they

interact with matter.

Relationships between , and energy for light (any needed constants (c, h) will be given)

Periodic trends with respect to:

• ionization energy

• electron affinity

• electronegativity

• size

• ionic charges

• electron configuration

Percent composition and empirical formulas

Predicting types of intermolecular forces for a compound (3 types) and predicting if a compound is polar

Enthalpy changes with phase changes

Interpretation of phase diagrams

Gas laws (A, B, C, D, G, and ideal) and gas stoichiometry

Gas chemistry in the troposphere and stratosphere (know issues AND reactions surrounding these topics)
