Chemical reactivity is studied in this chapter: precipitation, acid-base reactions, oxidation-reduction reactions, combination and decomposition, replacement reactions, combustion.
The classical chemical calculations are studied in this chapter: the concept of a mole, the atomic, molecular and molar masses, the relation between mass, mole and number of particles, the mass percent of an element, the combustion analysis, the chemical equations (coefficients and stoichiometry), the limiting reagent and the yield calculation.
The chemical calculations for solutions are studied in this chapter: the definition of a solution, molarity versus molality, electrolytes, the dilution of a solution, precipitation reactions, acid-base titrations.
The properties of gases are studied in this chapter: the pressure, the gas laws, the ideal gas equation, the relation between molar volume, molar mass and density, the Dalton’s law of partial pressures, the kinetic theory and speed distribution, the Graham’s law of effusion, the mean free path, the Van der Waals equation.
Thermochemistry is studied in this chapter: internal energy, heat and work, enthalpy, Hess’s law, enthalpy of formation, bond enthalpies, heat capacity.
Liquids and solids are studied in this chapter: intermolecular forces, phase transitions, heating curves, phase diagrams, properties of liquids, vapor pressure, relative humidity, crystal structures and forces, colloids.
Colligative properties of solutions are studied in this chapter: solution concentrations, solutions and solubility, gas solubility and Henry’s law, Raoult’s law, boiling point elevation, freezing point depression, osmotic pressure.
The rate laws in chemical kinetics are studied in this chapter: reactions rates, first-order and second-order reactions (specific rate of reaction, relation between concentration and time, half-time), radioactive decay.
The mechanisms in chemical kinetics are studied in this chapter: elementary reactions, intermediates, activation energy, Arrhenius equation, rate-determining step, reversible reactions, catalysis.
