Lessons illustrating the concepts included in the program. Numerical exercises after the inherent lesson, to be performed by students preferably working in groups under the supervision of a tutor, to exemplify and apply to practical cases the illustrated concepts.
The exam is constituted by a written part and an oral part. The written part, whose duration will be 90 minutes, is constituted by 10 questions, each valued up to 3 points. All questions have the same value. There will be no penalty for wrong answers. Sufficiency (18/30) in the written part will grant admission to the oral part, which will include a discussion of the written test and questions on the whole program. The final vote will be determined by taking into consideration both the results of the written and oral parts, though it will not be calculated as their exact average. The written test can be substituted by two partial tests, one taking place at midterm and the other at the end of the course, each including 5 questions for a 45' duration. Sufficiency in both tests allows direct access to the oral exam.
Atomic structure and periodic properties. Chemical bonds: covalent, ionic and metallic bonding. Intermolecular attractions. Mole, limiting reagent, stoichiometry. Thermochemistry and calorimetry.Thermodynamics: the three principles, enthalpy, entropy and free energy. Homogeneous and heterogeneous equilibria, state transitions and phase diagrams. Equilibria in aqueous solution: strong and weak acids and bases, hydrolysis. Solubility equilibria. Two-component systems: Raoult law and distillation. Colligative properties. Eutectic diagrams. Balancing of oxidation-reduction reactions. Standard reduction potentials. Batteries; Nernst law. Electrolysis. Corrosion and protection of metallic materials. Kinetics and catalysis.
On the Moodle platform (course Chimica per meccanici 23027) some interactive quizzes and exercises for self-evaluation are available, as well as several exam text specimens with solutions and a series of thematic sheets bearing the essentials of the theory and a number of problems for each subject.
