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

This course provides the fundamental chemical knowledge and chemical and physical atomic structure, chemical bonding, thermodynamics and chemical kinetics essential for understanding of the state and the transformation of matter , of natural phenomena and environmental and nature of 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.

Exam description

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

The written test must establish only the minimum level of necessary knowledge for the admission to the next oral exam. This test does not have a numerical evaluation and is based on the solution of 9 questions on the following topics discussed during the exercises and present in the appropriate section available to all the students in Aulaweb:

1) Inorganic nomenclature;

2) Balancing exchange ion reactions;

3) Stoichiometric calculations or numerical application of the perfect gas law;

4) Radiochemistry or representation of the electronic configurations of atoms and molecules or chemical bond;

5) Thermodynamic laws and definitions or calculation of the pH of strong acids and bases;

6) Redox reactions balancing or calculation of the cells potential difference or electrolytic cell sizing or calculation of the reaction heat;

7) Calculation of the equilibrium constant or composition;

8) Description of a state diagram or description of the relationship between the structure and a property or kinetics and catalysts;

9) Calculation of pH of weak acids and bases or organic nomenclature or metallurgy and corrosion.

The written test is considered passed with a number of correct answers greater or equal than to 5. 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:
