Learning outcomes of the course unit
Educational objectives of the course
1) Introduce students to the language and the scientific method.
2) Provide the student with the tools to understand the principal characteristics and behaviour of matter, guiding them to the understanding of the principal laws of physics and chemistry and problem solving (chemical calculations).
Course contents summary
1) Definition of matter and state of aggregation of matter.
2) The atom: protons, neutrons, electrons, electronic structure: Bohr's theory and wave theory.
3) The concept of mole, atomic and molecular weight: stoichiometry.
4) The periodic table and principal chemical and physical properties of atoms.
5) The chemical bonds: ionic bond, covalent bond (theory of Lewis, Valence Bond Theory and Molecular Orbital Theory); form of molecules; hydrogen bond; Van der Waals’ forces.
6) The chemical reactions: exchange reactions and redox reactions. Stoichiometry calculations.
7) Energy: kinetic energy and potential energy; virial theorem; heat and work; enthalpy, free and entropy energy
8) Gaseous state: ideal gas, kinetic theory of gases, real gases. 9) Liquid state: evaporation and vapour tension; boiling temperature and its variation with pressure. 10) Solid State: sublimation and vapour tension; melting temperature and its variation with pressure; diagram of the state of water.
11) The solutions: solutes and solvents; solubility, ideal and real solutions.
12) The chemical equilibrium: homogeneous and heterogeneous equilibria, the principal of migratory balance.
13) Acids and bases, according to Arrhenius, Brönsted and Lewis; equilibria in solution; Ka and Kb; pH; hydrolysis; buffers; acid-base titrations; indicators. 14) low solubility salts and solubility equilibria; Kps.
