Learning Objectives

Acquisition of important concepts of general chemistry, inorganic, stoichiometry and organic elements. The course is organized so as to provide a good understanding of the basic chemistry (inorganic and stoichiometry) and is divided into a theoretical part and a part that consists of exercises aimed at the solution of chemical problems. The aim of the course is to acquire reasoning skills to deal with the study of chemical phenomena with analytical and numerical methods.
