The course introduces the fundamental elements of the General Chemistry, which constitute the basic knowledge needed for the following courses of the Laurea degree. The concepts introduced in the course of General Chemistry are a requirement for the courses of Organic Chemistry, Enological Chemistry, Agricultural Biochemistry, Fermentation Biotechnology. The aim of the course is to introduce the student to basic principles of chemistry, providing information on the language of chemistry (symbols and formulas). The course aims at providing to the students the capability to understand the basic language of the chemistry, to be able to follow concepts requiring the basic knowledge of general chemistry, and to be able to solve elementary problems through the application of the introduced concepts.
