The course begins with elementary notions and does require previous knowledge of chemistry from high school.
Basic knowledges of mathematics and physics, provided during the years of high school, are required.

Final Examination: 

Six exam sessions are scheduled, on the dates set by the University calendar; the examination consists in a written test of 2hrs with the resolution of eight problems pertinent to: theory, stoichiometry and redox, molecular geometries, thermodynamics and chemical equilibrium, colligative properties, acid-base reactions and solubility, electrochemical cells. The student has passed the exam, only if the written test results are ≥ 18/30. The written test consists in a resolution and in a logical exposition of selected topics among the most important ones of the course.

Introduction and training goals
Teaching this course means giving the bases for understanding the macroscopic properties of matter, starting from the structure of atoms and molecules, and their properties. The course develops the criteria to understand the ability of a substance to react, or to break and to form bonds, and the corresponding energy exchanges, in relation with possible applications and with the behaviour of materials. The exercises will examine thoroughly, not only numerically, the aspects treated in class.

Knowledge and understanding
-acquisition of competences and tools suitable for the communication of the collection, the elaboration and the presentation of the data.
-acquisition of abilities suitable for the development and examination of further skills for a strong learning of basic notions, for a following autonomous acquisition of higher knowledge, and for continuous updating.

Applying knowledge and understanding (Skills and knowhow)
- acquiring the fundamental elements of general chemistry and inorganic reactivity;
- knowing the main chemical and physical factors that influence chemical reactions;
-developing the ability to describe analytically, to simulate, to analyze and to solve problems of physical-biological interest as well;
- showing the ability of extracting and synthesizing the relevant information;
- showing ability of communicating in an effective way and with the correct terminology, both orally and in writing.
