Learning outcomes

At the end of the course, the student knows the basic principles of general chemistry and the chemical properties of elements and compounds, which are necessary for the study of geological processes and materials. He can : - utilize the IUPAC nomenclature, SI units, concentration expressions; - illustrate the atomic structure of the elements and classify compounds on the basis of the different kinds of chemical bond; - perform stoichiometric calculations using mole, concentration, pH, solubility; apply the principles of chemical equilibrium to homogeneous and heterogeneous systems, and illustrate the properties of the different aggregation states; - use the Periodic Table to identify the characteristics of the main elements and of their inorganic compounds.

Teaching material is provided, available through username and password at VIRTUALE - Online teaching support - University of Bologna.

Teaching methods

Lectures with the use of PowerPoint presentations. Exercises aimed to solve stoichiometry problems. Laboratory experiments.

Numerical exercises and laboratory activity are focused to acquire practical skills.

In consideration of the types of activities and teaching methods adopted, the attendance of this training activity requires the performance of all students of modules 1 and 2 in e-learning mode and participation in module 3 of specific training on safety and health in places of study. Information on dates and methods of attendance of module 3 can be consulted in the specific section of the degree program website. 

Assessment methods

The final examination consists in an oral exam, which tests the acquired abilities and knowledge. During the exam, the student can use the Periodic Table of the Elements. The first question of the test is a stoichiometry problem aimed to verify the student's knowledge of the names of inorganic compounds and of the meaning of chemical reaction, which are mandatory requirements to pass the exam. Further questions are addressed to evaluate the student's knowledge of the basic principles of general chemistry and of the chemical properties of elements and compounds.

Teaching tools

Overhead projector, PC, video projector, powerpoint presentations, laboratory instruments and tools.

The slides used in the lectures can be downloaded as PDF files from the Virtuale platform. Texts of problems and exercises will be available in the same platform.
