AIMS AND CONTENT

AIMS AND LEARNING OUTCOMES

The course is meant to provide students with basic knowledge on the structure of the matter (atomic structure, chemical bonding, aggregation states) and on the principles governing chemical equilibrium in homogeneous and heterogeneous systems, with particular attention to reactions taking place in aqueous solution. Preliminary knowledge is also provided on chemical properties of the main elements of the periodic system and their most important compounds, and on the regularities of such properties, which will be treated in more detail in subsequent courses.

Therefore, the course aims to provide students with the indispensable tools to understand matter and its chemical transformations and it is a prerequisite to all the chemistry courses of the following years.

PREREQUISITES

This is the first chemistry course, so it is not necessary to have any prerequisetes at university level. The basic knowledge of mathematics and physics acquired at high school  are sufficient to understand the addressed topics. 

TEACHING METHODS

The course includes both lectures and practical sessions in the classroom, during which exercises are carried out on the topics covered in the theoretical lessons.

EXAMS

EXAM DESCRIPTION

The exam is joint for the two modules and consists of a written and an oral part. The written test consists of numerical exercises on the topics covered during the course (both 1st and 2nd module). Only by obtaining a sufficient score for the written test, the student is admitted to the oral exam. During the course two partial written tests are carried out. The student who passes both partial tests is exonerated from the written exam.

The oral exam is always conducted by two professors with experience in examinations in the discipline and lasts at least 30 minutes. The final evaluation also takes into account the laboratory activity, documented by the reports delivered and corrected during the course, a paper copy of which must be taken at the oral examination

ASSESSMENT METHODS

The exam consists of a written and an oral part on topics developed during the course. The oral exam is always conducted by two teachers with experience in examinations in the discipline and it lasts at least 30 minutes. In this way, teachers are able to accurately verify the achievement of the educational objectives. When these are not achieved, the student is invited to deepen the study and ask further explanations to the teachers.
