Expected learning outcomes
The course aims at providing the necessary background for the interpretation of chemical phenomena, for the understanding of the structure and properties of molecules and crystalline solids, and the comprehension and handling of energetic phenomena concerning chemical and electrochemical systems.
|
Prerequisites / Assumed knowledge
To make profit of the course it is required to master the basic notions of general chemistry, the symbols of elements and compounds, the simplest nomenclature both organic and inorganic, the balancing of elementary stoichiometric reactions.
