AIMS AND CONTENT

LEARNING OUTCOMES

Aim of the course is giving the students basic elements of general and inorganic chemistry, driving them to language and method of chemistry, supplying the necessary tools for a better understanding of chemical aspects in the following courses to be attended in their university studies.

TEACHING METHODS

The course is delivered through lectures and numerical exercises lessons. We also carry out various laboratory exercises whose attendance is mandatory. The teaching materials used are mostly reported in the Aulaweb site.

SYLLABUS/CONTENT

Introduction. Homogeneous and heterogeneous systems. Pure substances and solutions. Atoms and molecules. Geometrical lattices, atomic number, atomic and molecular mass.

EXAM DESCRIPTION

The exam consists of a written test and an oral interview. Passing  the written test is mandatory  for access to the oral exam. The final vote takes account of both components.

ASSESSMENT METHODS

The written tests take place in the academic holiday, the dates published in the course of study site (www.biotecnologie.unige.it).
The oral evidence generally place a few days later, according to the availability of the Committee and the needs of the students.
The days of the written test will be indicated in the site www.biotecnologie.unige.it,
Through the written test the ability to apply the acquired theoretical concepts is evaluated, while in the oral test the acquisition of theoretical knowledge is examined. Access to the oral test is allowed only to students obtaining a minimum score  of 18/30 in written exam. Partecipation to all the laboratory exercises is compulsory to be admitted to the oral exam,
