General and inorganic chemistry
Code: G250E-
Teacher:  Maria Cristina Bellucci
CFU subdivision: Lectures: 5
Practices in classroom: 1
Basic aims:  The objective of this course is to give students the basic concepts for understanding the structure and properties of the matter and the manner in which substances can be transformed into each other.
Acquired skills:  With this teaching, students acquire the language and basic knowledge necessary to his basic training which in turn will be applied to courses of chemical professional level.
Course contents:  The course of General and Inorganic Chemistry will be a set of information expressible in laws. The first part of the course lays the foundation for elementary face and overcome two fundamental aspects of General Chemistry that are the theory of chemical bond and chemical thermodynamics. The second part of the course deals with the study of chemical reactions and their feasibility. Each topic is supplemented with a number of exercises that illustrate the validity of the concepts presented. The third part will cover the chemistry of the elements with particular attention to those that are essential to plant and animal life. At the end the student will acquire a critical attitude towards the matter that will put you in a position to deal with: i) topics not covered in class ii) other vocational courses in chemical character.
Program:  Introduction: basic concepts. - The measures and the metric system-Atoms, molecules, and ions. - The states of matter, atomic theory, atomic structure, periodic table - Stoichiometry. - Law of conservation of mass, chemical equations-energy relations: the first law of thermodynamics. - The thermodynamic state function entalpia.-atomic structures of atoms: fundamental concepts, uncertainty principle; representation of the orbitals (orbitals s, p, and d). Structure-mail: periodicity. - Orbitals in atoms and electronic multi-periodic properties of chemical bonds. - Symbols and Lewis octet rule, ionic bond, covalent bond-structure of molecules and molecular orbitals, VB and MO theory - Theory of repulsion between electron pairs in the valence layer (VSEPR model) hybrid orbitals and shape of the molecules. Gas. - Ownership of the gas pressure, gas laws. Liquids, solids and intermolecular forces. - Phase equilibria; intermolecular attractive forces, hydrogen bonding. Solutions. - Ways of expressing concentration, electrolyte solutions, colligative properties. Chemical equilibrium. - Law of mass action and equilibrium constant (unit of measurement of concentrations and expression of the equilibrium constant); heterogeneous equilibria, use of the equilibrium constant, Le Chatelier's principle. Equilibria in aqueous solutions, acids and bases. - Water; theory of acids and bases according to: a) Arrhenius, b) Broensted-Lowry c) Lewis; pH scale, strong acids and bases, weak acids. Chemical thermodynamics. - Enthalpy, entropy, Gibbs energy. Electrochemistry. - Redox reactions, oxidation-reduction potential and their application. Descriptive inorganic chemistry. - Periodic Table: blocks s, p, d, f. Groups and periods. Changes in the properties along the periodic groups and periods ..

Prerequisites:  Being a basic course there are no prerequisites but the knowledge acquired in secondary school.
Preparatory instructions:  none
Learning materials:  text book: J.C. Kotz, P.M. Treichel, J.R. Townsend “ Chimica” V Edizione, Casa Editrice EdiSES.

Other info:  During the frequentation of the General an Inorganic chemistry course, there are two ongoing trials; the first will take place in mid course, the second, the last week of the course. Can access to the second test only students who have passed the first test with a score greater than or equal to 18. To pass the exam both tests must be sufficient. The final grade is the average of two grades obtained in both ongoing trials.
I don't oral interview.
The ongoing tests require enrollment.
The type of examination tasks consists of a variable number of exercises on all topics and according to the examples shown during exercises in the classroom.
For those who do not exceed the ongoing trials and for those who decide not to attend, the examination will consist of a single written test on dates set within each examination session. The test will consist on differents exercises on the entire program.
