Learning Objectives

The task of this lecturing of General and Inorganic Cemistry is giving the students the first notions of Chemistry which will constitute the scientific-cultural backgorund necessary to follow the advanced chemical courses of next years.


Course Structure

The way of proposing the cours will occur trough lectures, exercises on the points of program and laboratory experiences which students have to write a report about.
