GENERAL AND INORGANIC CHEMISTRY
Learning outcomes of the course unit
The aim of the course is to give the fundamental chemical concepts required to face the study of Chemistry. Particular emphasis is given to three aspects of the modern chemistry, the structural, energetic and kinetic ones, involved in all chemical problems. The theoretical treatment of the fundamental concepts is followed by examples . Care is given to teach formal correctness of language, and to highlight connections among different parts of the program.
