Prerequisites: Simple math skills are required.
Target skills and knowledge: Composition of matter and its transformations giving the basis for the application of the general principles of Chemistry to the processes that occur in nature at the level of the soil and vegetation.
In particular, the course provides the basic notions for understanding the properties of chemical elements, their compounds and their transformations. The course consists of theoretical lessons interspersed with practical examples and exercises. The resolution of the exercises, related to the arguments developed in the theoretical lessons, is of fundamental importance to accustom the student to the scientific approach applicable to problems of a practical nature.
Examination methods: The exam is written and with multiple choice theoretical questions, open-ended questions and stoichiometry exercises for a total of 12 answers, each of them with a predefined maximum score. The time available for completing the exam is 3 hours.
Assessment criteria: The assessment of the student's preparation will be based on his/her understanding of the covered topics, the proposed methodologies and on the ability to apply them independently in stoichiometry exercises.
Course unit contents: States of aggregation of the matter. Constituents of the atom, ions, atomic number, atomic masses, atomic mass units, isotopes, mole, Avogadro number, molecular masses, percentage composition of a compound, empirical formula and molecular formula. Atomic structure: atomic models of Thomson and Rutherford, electromagnetic radiation, atomic emission spectra, hydrogen emission spectrum, Heisemberg principle, Schröedinger wave equation, quantum numbers, atomic orbitals, energy level distribution in the atom of hydrogen and in the polyelectronic atoms. Periodic classification of the elements. Nomenclature of inorganic compounds. Chemical reactions: calculation of stoichiometric coefficients, weight correlations between reagents and products, reduction oxide reactions and their balancing.Chemical bond: ionic bond, covalent bond, molecular orbitals ("valence bond" theory), hybrid atomic orbitals, resonance, Lewis formulas, octet rule, octet expansion. Geometric structure of molecules, polarity of molecules. Molecular orbital theory (MO). Dative bond: coordination compounds. Metallic bond. Secondary bonds (dipole-dipole interactions, induced dipole-dipole, induced dipole-induced dipole, hydrogen bond and its implications on the physico-chemical properties of the compounds).Properties and laws of ideal gases, real gases, Van der Waals equation, Andrews isotherms. Liquid state: properties; state diagrams of water and carbon dioxide. Solutions: concentrations, molarity, molality and normality, colligative properties of ideal solutions, degree of dissociation, solubility product. Chemical equilibrium: law of mass action, Le Chatelier principle. Acid / base theories. Conjugated couples and relationship between Ka and Kb. Ionic product of water, acid and base strength, dissociation and pH, common ion, hydrolysis of salts, buffer solutions, poorly soluble salts and solubility product. Galvanic cells. The electrode potential and concentration. Use of the table of standard potentials and Nernst equation.
Planned learning activities and teaching methods: There are theoretical lessons and numerical exercises as well as assisted laboratory exercises.
The lectures are held by the teacher of the course with the help of computer aids (slides).The theoretical lessons must be supplemented by a constant personal study and the stoichiometry exercises carried out in the classroom are only examples on which to deepen the personal preparation. The laboratory exercises are held at the end of the course and are intended to bring the student closer to the practical application of the methods learned.
Additional notes about suggested reading: Slides of the lessons can be downloaded from the web site moodle.
A General Chemistry text and a Stoichiometry text at university level are required. A number of exercises proposed by the teacher and integrated with stoichiometry texts will be carried out during the course.
