| Learning activities | Base |
| Area | Fisica e chimica |
| Academic discipline | CHIM/07 |
| Type of study-unit | Obbligatorio (Required) |
| Language of instruction | Italian |
| Contents | Atomic theory. Properties of the gases. Thermodynamics. Phase equilibria and solutions. Chemical equilibrium. Equilibria in solution. Electrochemistry. Kinetics. Atomic and molecular structure. Chemical bonding. |
| Reference texts | David W. Oxtoby, H. P. Gillis & Laurie J. Butler, Chimica Moderna, EdiSES, Napoli |
| Educational objectives | Basic knowledge of general chemistry. Acquisition of the bases for the understanding of chemical phenomena relevant for technologies and, in particular, those related to the interactions between human activity and the environment. Acquisition of the knowledge necessary to evaluate the effects of the use of technologies and to know how to protect the environment. |
| Prerequisites | Knowledge of mathematics acquired in secondary school: Algebraic equations of first and second degree, systems of linear equations, inequalities, powers and logarithms, trigonometric functions, use of graphics and percentages, derivatives and integrals. |
| Teaching methods | Face-to-face lessons and practical training as well as remote teaching. |
| Other information | There are eight exam sessions in the following periods: January 2022; (2 dates) February 2022; June 2022 (2 dates); July 2022; September 2022 (2 dates). The dates can be found in the following site http://www.ing.unipg.it/ |
| Learning verification modality | The exam consists of a written test lasting 90 minutes. The test implies 20 answers to numerical problems and theoretical questions. Each correct answer gains 1.5 points; no points for a wrong answer or no answer. The written test is followed by an oral examination, which consists mainly in a discussion of the written test and in some questions on the atomic structure and the chemical bonding. During the written test it is possible to check books and student's notes. For information relative to students with disabilities or specific learning disorders see the WEB page http://www.unipg.it/disabilita-e-dsa |
