|SCIENTIFIC DISCIPLINARY SECTOR||CHIM/07|
The course develops the major topics of Chemistry, with particular attention to applications and technological aspects. It is organized according to a learning path that starts from the model of the atom, to then describe chemical bonds, gases, liquids and solids, their reactions and properties. The main concepts of thermodynamics, equilibrium and kinetics will allow students to evaluate the transformations of matter and the bases of chemical processes and technologies.
The course aims to provide fundamental chemical knowledge required to describe the structure and behavior of materials and to address the interpretation of natural, environmental and technological processes.
The course aims to provide students with the ability to understand and critically deal with chemical issues concerning structures and properties of materials and their technological applications, in relation to the atomic structure, types of bonding, thermal effects, reaction rate and spontaneity of chemical reactions, chemical and physical equilibria.
By the end of the course, students should be able to:
describe and exemplify atomic models, atomic, ionic and molecular structures;
describe the characteristic of states of matter;
describe examples of state diagrams;
analyze and solve quantitative problems on stoichiometry, essential thermodynamic, chemical kinetics, electrochemistry and equilibrium composition of reaction mixtures;
interpret the main properties of materials in technological applications and natural processes;
evaluate the behavior of solutes in aqueous solutions;
hypothesize the behavior of a chemical system upon chemical reactions in different conditions, by using the aquired skills.

Written exam with optional oral exam. Student who have passed the written test with a grade higher than, or equal to, 18 may decide whether to accept the grade of the written test or hold an oral exam on the scheduled days. In the latter case the final grade will result from the grade average of written and oral exams.
At the end of the course, the student must have acquired the basic knowledge necessary to understand and deal with issues concerning: chemical reactions and processes, structures and properties of materials, their technological applications.
The written exam will evaluate the student's ability to describe and exemplify fundamental concepts of chemistry reported in the course program, to apply concept to the solution of quantitative problems concerning stoichiometry, thermodynamics, kinetics, equilibrium reactions and chemical processes, to interpret phase diagrams, to describe and compare structures and properties of atoms, compounds and materials proposed as esamples.
Evaluation parameters will be the correctness of the numerical results, the completeness and quality of the exposure, the appropriate use of the specialized lexicon.
