Objectives

The course of general and Inorganic Chemistry intends to provide the basic concepts of chemistry for the student to face the subsequent courses with a chemical background,

At the end of the course the student should:
- know the basic chemical notions on composition, structure, properties and transformation of matter
- have the basic knowledge on atomic structure, the nature of the chemical bonding and molecular structure
- have the basic knowledge of properties of gases and solutions
. know how to balance a chemical reaction and solve stoichiometry problems
- know how to evaluate concentration and dilution of aqueous solutions

Teaching Methods

The course consists of 48 hours of lectures and 12 hours of stoichiometry .

Teaching is carried out according to a standard fashion, through lectures supported by slides and the use of a board.

Evaluation methods

Verification of learning:

The exam consists of a written and of an oral test. The written exam is made of a multiple choice test of 10 exercises and 4/5 open questions, meant to evaluate the comprehension of the fundamental principles of chemistry and the ability of the student to apply them to real cases. In order to pass the exam the written part must be approved with 18/30 points. The oral part is an oral discussion of 30 min. ca.
The final mark will be the result of the overall evaluation of both the written and the oral parts.
