The aim of the course is to acquire the main concepts of General Chemistry and some notions of Inorganic Chemistry. In particular:
- models and general concepts for the explanation and prediction of some physics and chemistry properties of systems of increasing complexity: single atoms, ions, molecules, pure substances, macroscopic systems of one or more components;
- concepts and methods to qualitatively and quantitatively predict the variations of the intensive and extensive properties of chemical systems in evolution.
Numerical exercises integrate the knowledge acquired by the student in the theoretical part of the Course, in order to to teach the student how to solve problems of chemical interest.
The experiments in the General Chemistry laboratory integrate the knowledge acquired by the student in the theoretical part of the Course. The student learns how to manage problems of chemical interest, obtains information about the common equipment present in a chemical laboratory and how to work in safe conditions.
