15750 - Basics Principles of Chemistry

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

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

The final exam consists of a written test that aims to assess the achievement of learning objectives:
- Knowledge of the atomic structure of matter and its properties in various states of aggregation
- Knowledge of methods of solving exercises of basic chemistry
The written test is evaluated on the basis of the answers to questions related to theory and to the resolution of exercises
