GENERAL AND INORGANIC CHEMISTRY
Learning outcomes of the course unit
The objective of the course is to provide the first year students with the basic concepts of chemistry
Course contents summary
Chemical instruments. Atoms and elements. Compounds and molecules. Chemical reactions: an introduction. Reactions in water solutions. Thermochemistry. Atomic and molecular structure. Structure of the atom. Electronic configuration of atoms and periodic properties. Basic concepts on the chemical bond and on the molecular structure. – Further concepts on the chemical bond: orbital hybridization, molecular orbital theory and metallic bond. The states of aggregation: gases and their behaviour. Intermolecular forces: liquids and solids. Solutions and their behaviour. The control of chemical reactions: thermodynamic and kinetic aspects. The principles of thermodynamics and their implications in a chemical context. Spontaneity of the chemical reactions. Enthropy and free energy. Chemical equilibrium. The chemistry of acids and bases. Buffer systems. Precipitation reactions. Thermodynamics of redox reactions. Electrochemistry. Kinetics: rate and mechanisms of chemical reactions – Chemistry of the elements and of their compounds: the s and p blocks and the transition elements of biological relevance.
Stoichiometry. Equivalent weight. Chemical reactions. Normality. Redox reactions. Principles of volumetric analysis. Balance in pH solutions. Buffer solutions.

The course will be made up of lectures, supplemented by material accessible online on the Biotechnology site (biotecnologie.unipr.it). There will be impromptu tests during the year to check student level of comprehension.
The exam will be written and consist of a series of questions which will retrace, in order, the course syllabus: atomic and molecular theories (nomenclature and stoichimetry), chemical bonds (molecular forms), thermodynamics (thermochemistry and balance in solutions) and kinetics (reaction mechanisms).
