(syllabus)
Atom Structure: orbitals, poly-electron atoms, periodic table; bonds in chemistry (Lewis theory and VSEPR, Valence bond theory and hybridization); delocalized bond. Mass relationship in chemical reactions; redox and oxidation number. Solids: metallic, ionic, covalent and molecular crystals (weak bonds: van der Waals and hydrogen bond) Gases: the ideal gas law, gas mixture, Dalton law, partial pressures. Thermodynamics: nature and type of energy, the zero law of T.D., heat capacity, the first law of TD and Enthalphy. Calorimetry and thermochemistry. Born-Haber cycle; Carnot cycle. The second law of TD, Kelvin and Clausius statements, entropy and free energy, equilibrium conditions. Liquids: saturation vapor pressure, Clapeyron law (thermodynamic demonstration), phase change, phase diagrams. Variance. Chemical equilibrium: the equilibrium constant and the equilibrium law, heterogeneous equilibrium, thermal dissociation and dissociation degree. Properties of liquid solutions: concentration units, the Raoult law and distillation, colligatives properties and freezing diagram, electrolytes. Arrhenius, Brönsted and Lewis acids and bases; pH; determination of pH for acidic and basic solutions, salt solutions, buffers.
