Academic Year 2020/2021

Learning outcomes

Upon completion of the course the student has acquired a good knowledge of the fundamentals of General and Inorganic Chemistry. In detail the student is able to use the basic knowledge of General Chemistry in order to evaluate the relationship between chemical structure and chemical reactivity of the most important inorganic compounds and apply the chemical equilibrium concepts.

Assessment methods

The final written exam consists of numerical exrcises and questions on the main topics of the course.

One ongoing written tests could be planned during the course about stoichiometry problems and open questions on the topics covered so far. In order to pass the examination the students must obtain at least 18/30 and the final marks will be the arithmetic average.
