OVERVIEW

Study of chemical and chemical-physical basic of technologies, with particular reference to materials, properties and interaction with the environment, providing a synthesis of common principles of state and transformation of matter.

AIMS AND CONTENT

LEARNING OUTCOMES

To supply a basic chemical culture, required to describe the behaviour of the materials and to face the interpretation of the natural, environmental and technological processes.

AIMS AND LEARNING OUTCOMES

The training activities proposed in the form of lectures, exercises and numerical applications, associated to the individual study, will allow the student to:

know the atomic structure;

understand the mechanisms of strong and weak chemical bond formation;

know the structure of solids, liquids and understand the gas state equations;

understand the relationships between electrical, magnetic and mechanical structure and properties;

to know the main thermodynamic and kinetic variables involved in the transformation of matter;

evaluate the conditions of the chemical equilibrium;

determine quantitatively the equilibriums in gas phase, in aqueous solutions and in the electrochemical systems;

discuss all the proposed activities with a scientific method and appropriate language.

Teaching methods

Lectures and exercises in the classroom. The assessment of learning and operational skills during the course will take place through the monitoring carried out during the numerical exercises.

The transversal skills in terms of independence of judgment will be acquired through the classroom performance of the exercises to be carried out in a group.

SYLLABUS/CONTENT

Nature of the matter: composition of the atom and its stability; matter-energy interaction; quantization of energy and wave nature of the matter; Schrodinger equation an atomic structure; periodic properties of the elements; valence bond theory and molecular orbitals; band structure theory in the solids; amorphous and crystalline structure of solids; properties of liquids; perfect and imperfect gases; mechanical, electric and magnetic properties.

Fundamentals of the chemical reactivity: first law of thermodynamic; enthalpy in chemical reactions; second law of thermodynamic and spontaneous change; entropy and third law of thermodynamic; spontaneous chemical reaction and Gibbs function; chemical equilibrium; phase diagrams of pure and mixed compounds; aqueous solutions, strong acids and bases,  weak acids and bases, solubility of salts; electrochemistry and Nernst law; reduction potentials, electrolytic cells and Faraday law; voltaic cells and storage battery; metallurgy and metal corrosion, rate of reaction and kinetic models; Arrhenius law, transition complex and catalysis. Nomenclature of chemical compounds.

Numerical applications: units; mole; formulas; atomic and molecular weight; chemical reactions; gas laws; concentrations; colligative properties; thermodynamics and thermochemistry; electrochemistry; shift of the chemical equilibrium; pH.

RECOMMENDED READING/BIBLIOGRAPHY

The teaching material used during the lessons will be available in aulaweb, as well as the examples of final tests proposed in previous years with the related solutions. The notes taken during the lessons and the material in the aulaweb are enough for the preparation of the exam, but the following books are suggested as supporting and in-depth texts.

EXAMS

Exam description

The exam includes a written and an oral exam with open questions.

 

The written test is structured in 10 questions consisting mainly of numerical exercises on the following topics covered during the exercises and present in the appropriate section available to all students in Aulaweb:

Inorganic nomenclature; Balancing exchange ion reactions; Stoichiometric calculations Numerical application of the perfect gas law; Solution concentration; Radiochemistry or representation of the electronic configurations of atoms and molecules or chemical bond; Thermodynamic laws and definitions or heat of reaction; Redox reactions balancing; Calculation of the cells potential difference or electrolytic cell sizing; Calculation of the equilibrium constant or composition; Description of a state diagram or description of the relationship between the structure and a property or kinetics and catalysts; Calculation of pH of strong or weak acids and bases; Organic nomenclature or metallurgy and corrosion.

The vote will be out of thirty. Students who have obtained a mark greater than or equal to 16/30 are admitted to the oral exam.

3 appeals will be available in the winter session and 3 in the summer session.

 

The oral exam is structured on 3 questions of weight 10/30, one for each of the 3 chapters related to: 1) structure of matter; 2) transformation of matter; 3) relationships between structure and properties of materials. In more detail, for each chapter one of the 16 questions listed below will be placed.

Part 1:

E.M. waves, spectra and color; E.M. waves associated with particles; Quantum numbers; Radioactivity; Nuclear energy; Diatomic molecule configurations; σ and π bonds; Hybridization; Polar molecules; Delocalized electrons and resonance; Weak and hydrogen bonds; Theory of the bands and solids bond; Metal structures and alloys; Ionic lattices and reticular energy; Defects and surface; Kinetic theory and gas laws.

Part 2:

First TD principle and enthalpy; Second TD principle and entropy; Gibbs energy and chemical equilibrium; Equilibrium constant and temperature; Equilibrium constant and pressure; Solubility product; H2O state diagram; Electrode potentials; Daniell cell; Electrolysis; pH definition and calculation; Weak acids and bases in water; Hydrolysis of salts and pH; pH of buffer solutions; Reaction rate and collisions theory; Catalysis.

Part 3:

For each written test passed 2 oral appeals are possible in the same session.

The grade obtained in the teaching will be the average of the marks given in the two modules in which the teaching is divided.
