Learning outcomes

At the end of the course the students has the basic knowledge of chemistry, is able to write chemical equations, to describe the chemical-strctural characteristics of matter, to understand the kinetics of a chemical reaction and the heat involved.

Course contents

Requirements/Prior knowledge

A prior knowledge of the basic concepts of chemistry is not required to attend with profit this course.

Fluent spoken and written Italian is a necessary pre-requisite: all lectures and tutorials, and all study material will be in Italian.

Course Contents

Atomic structure of matter : atoms, fundamental particles, atomic number, isotopes, atomic mass, mole and molar mass. Nomenclature of compounds.

Electronic structure of atoms and periodicity of atomic properties: the wave nature of matter, wave mechanics, atomic orbitals, quantum numbers, electron configurations of the elements and periodic properties.

Chemical bonds : ionic bonds and structure of ionic crystals. Covalent bond: hybrid orbitals and molecular structure, molecular orbital theory. Covalent crystals. Polarity of molecules. Metallic bond: band theory. Weak interactions.

Stoichiometry, chemical reactions and redox.

States of matter: gases, ideal gas law, mixture of gases and real gases. Liquid state: solutions and measures of concentration. Exercises. Solids: kinds of crystals.

Thermochemistry: Hess's Law of heat. Standard reactions enthalpies, enthalpies of formation and combustion.

Chemical kinetics: reaction rate, rate law and activation energy. Catalysts.

Chemical equilibrium: the equilibrium constant, homogeneous and heterogeneous equilibria, the responsa of equilibria to changes.

Ionic equilibria in acqueous solutions. Acids and bases. pH determination.

Electrochemistry.

Teaching methods

Theoretical lessons and exercises

Assessment methods

Achievements will be assessed by the means of a final exam. This is based on an analytical assessment of the "expected learning outcomes" described above.

In order to properly assess such achievement the examination is composed of a written session, which consists of a test, duration 2h, composed of theorethical questions and exercises, according to the course contents described above.

For the students that obtained at least 18/30 in the written session and aim at improving this score, an oral session, consisting of a review of the written output and questions on the fundamental principles of Chemistry, is possible, but not obligatory.

To obtain a passing grade, students are required to demonstrate a knowledge of the key concepts of the subject:

- atomic structure of matter and its properties in various states of aggregation

- methods of solving exercises of basic chemistry

Teaching tools

Overhead projector. The material used during the lessons is available online to the students.
