- Educational objectives
- The student will be given basic knowledge of the main aspects of general chemistry, concerning in particular:
- the nature of atoms and molecules and their electronic structure
- chemical reactions and stoichiometry. The student will be able to write chemical reaction equations and calculate quantities
- the principles of chemical equilibrium in the gas phase and in solution. Ability to make simple pH calculations and calculations on redox equilibria.
- chemical elements and their main types of compounds. Ability to make qualitative chemical predictions based on periodicity.
- the main classes of organic compounds - Prerequisites
- Elementary arithmetics. First and second order equations. Basic physical concepts: units, force, work, energy.
- Teaching methods
- Frontal lectures with explanations written at the moment on projected slides. Exercises and exemplifications on chemical calculations, stoichiometry and chemical equilibria.
- Other information
- The teacher may be contacted via email for appointments or additional information
- Learning verification modality
- The exam is composed of a written and an oral test. The written exam consists of multiple-choice questions and open-answer problems, each with its own point value towards a total of 30 points. In the oral exam the student will discuss two/three of the main subjects in no more than 20 minutes. To qualify for the oral part it is necessary to achieve at least 15 points in the written test. The final marks will be obtained as the mean value of the written and oral evaluations.
