CHIM/03 - GENERAL AND INORGANIC CHEMISTRY

Elearning Seminars

The teaching is organized as follows:

Learning outcomes

Module: Theory
-------
The course provides the fundamental concepts of General Chemistry and some basics of Inorganic Chemistry. In particular:
- models and general concepts as means of justification and prediction of physical and chemical properties of systems of increasing degree of complexity: atoms, molecules, substances, multi-component systems (homogeneous and heterogeneous).
- concepts and methods for predicting qualitative and quantitative changes of intensive and extensive properties of evolving chemical systems.

Module: Laboratory
-------
Numerical exercises complement and deepen the subjects addressed in the theoretical part. They are an essential tool for the student in order to improve the skill to solve real problems of chemical interest.
The experiments in the chemical laboratory complete the knowledge acquired in the theoretical and numerical exercises parts, facing the student with real problems of chemical interest. The student gain also information about the common equipment present in a chemical laboratory and how to work in safe conditions.
