| CHIMICA GENERALE E INORGANICA
(objectives)
The aim of the course is to provide the basic principles for the study of the atomic structure of matter, the conditions of formation of chemical bonds, reactivity, chemical equilibrium and properties of the main elements. Knowledge of these concepts is fundamental to undertake the study of the chemical materials characterizing the degree course.
At the end of the course the student will have to show: A) to know the fundamental principles of General and Inorganic Chemistry: the structure of the atom, the properties of the elements and their ability to form compounds, molecular structures, chemical reactions, exchanges of energy, the states of the matter, the chemical kinetics, the equilibria in solution, the acid-base properties, the electrochemistry, the chemistry of the elements of the main groups B) have acquired application skills with reference to the balancing of reactions, stoichiometric calculations and solving acid-base problems, solubility product and electrochemistry C) being able to independently evaluate and resolve problems concerning course contents D) have developed a good oral and written exposition capacity of the acquired concepts E) be able to deepen the topics in different contexts and independently.
