Learning objectives
The course aims to introduce students to the study of chemistry and technology. In particular, the student should be aware that the continuation of studies provides a systematic deepening and widening of the elements of chemistry and physical chemistry covered in this course that is educationally prerequisite to all other courses in subjects like chemistry and technology provided by the degree programme in Food Services Management and Human Nutrition.
Expected learning outcomes
The student is able to recognize the chemical nomenclature, perform stoichiometric calculations and recognize the properties of the chemical solutions. Moreover, learns to define the state and the stability of systems (one or more components distributed in one or more phases) when is known the composition, temperature and pressure. The concepts of chemical kinetics allow the student to outline the processes in terms of elementary steps, subsequent or simultaneous, and the temperature dependence of the respective rates.
