CHEMISTRY

LEARNING OUTCOMES

The course provides a basic chemical culture, indispensable to describe the behaviour of the materials and to face the interpretation of the natural, environmental and technological processes

AIMS AND LEARNING OUTCOMES

Attendance and active participation in the proposed training activities and individual study will allow the student to:

- solve numerical exercises on the balancing and stoichiometry of chemical reactions.

- Analyze the elementary chemical properties of liquids, gases and solutions.

- Understand the structure of ionic, covalent, metallic and molecular solids.

- Solving thermodynamics, equilibrium and kinetic exercises related to chemical and electrochemical systems.

- Know the basic fundamentals of organic chemistry and nuclear chemistry.

- Describe the main pollution phenomena

PREREQUISITES

For a successful learning, basic knowledge of mathematics and physics is required, but no formal prerequisites are required.

TEACHING METHODS

The course includes lectures in the classroom. Lectures include the presentation of theoretical content and numerical exercises aimed at encouraging the learning and discussion of specific examples of chemical phenomena

SYLLABUS/CONTENT

Atomic structure of the matter: atomic models, quantum numbers, Heisenberg uncertainty principle, Pauli exclusion principle.

Periodic table.

Nuclear energy and radioactivity: Radioactive emissions, half-life.

Atomic bonds: covalent, ionic, metallic bond, hydrogen bond, weak bonds.

Inorganic nomenclature: Oxides, anhydrides, hydroxides, acids, Salts.

Introduction to organic chemistry: nomenclature, polymers.

Stoichiometry of the chemical reactions, concentration of the solutions, quantitative exercises.

Solid state.

The gas laws: Boyle’s, Charles’s, Gay-Lussac’s and Avogadro’s laws, ideal and real gas law, the volume of gases in the chemical reactions.

Fundamentals of Thermodynamics: 1° and 2° principle of Thermodynamics, Enthalpy, Entropy, free Energy.

Chemical equilibriums: the equilibrium constant, relation between free energy and equilibrium.

Heterogeneous equilibrium: state diagrams.

Chemical kinetic: reaction order, Arrhenius’s law.

The solutions: pH and the hydrolysis.

Electrochemical systems: batteries, fuel cells, electrolysis.

Water, Air and Soil Pollution. 

RECOMMENDED READING/BIBLIOGRAPHY

The notes taken during the lessons and the material in the aulaweb are sufficient for the preparation of the exam, but the following books are suggested as supporting and in-depth texts.

- M. Panizza, G. Cerisola, Esercizi di chimica generale per Ingegneria, Ed. ECIG.

- Dispense di Chimica (Barbucci, Panizza)

On the aulaweb site of the course there are examples of final tests proposed in previous years with the related solutions

EXAM DESCRIPTION

The exam consists of a written test that includes both exercises and theoretical questions with optional oral (the student who has passed the written test with a grade greater than or equal to 18/30 can decide whether to take an oral exam on the established days or accept the written test score).

The written test can be repeated, but in this case the vote of the last written is valid.

To access the oral exam students must have passed the written test with a minimum grade of 16/30 and the grade obtained in this form will be the average between written and oral exam.

Three exam sessions will be available for the 'winter' session (January, February and during the teaching break provided by the Scuola Politenica at Easter) and 3 calls for the 'summer' session (June, July, September and during the autumn break provided by the Polytechnic School). No extraordinary appeals will be granted outside the periods indicated by the Polytechnic School, except for students who have not included in the study plan training activities in the current academic year.

The results of the exams will be published on the aulaweb website of the course.

ASSESSMENT METHODS

The written exam consists in solving with chemical methodology and tools problems concerning chemical reactions and stoichiometric calculations, thermodynamics and chemical kinetics, reaction equilibria and in solution and electrochemistry. The student will also have to answer short theoretical questions concerning the atomic structure and the states of matter and its transformations.

The written test will be discussed at the oral exam and the student's ability to understand and interpret the chemical processes and transformations as well as the ability to reason critically will be evaluated.
