CHIMICA GENERALE

The course aims to transfer to the student the basic knowledge of general chemistry. The student will be directed to study the atomic and molecular structure, the periodic properties of the elements, the chemical bonds, the chemical reactions, the properties of gases and solutions as well as the quantitative aspects of general chemistry.

Frontal lessons

Information for students with disabilities and/or DSA.

As a guarantee of equal opportunities and in compliance with current laws, interested students can ask for a personal interview in order to plan any compensatory and/or dispensatory measures, based on their specific needs and on teaching objectives of the discipline. It is also possible to ask the departmental contacts of CInAP (Center for Active and Participatory Integration - Services for Disabilities and/or DSAs), in the persons of professors Giovanna Tropea Garzia and Anna De Angelis.
