To homogenizer the knowledge of students with different backgrounds
The student should learn the contents of General Chemistry included in the program, to know how to do the experimental work and solve the proposed problems.
The student should be able to work in group, to know how to interpret the results obtained in the laboratory and to develop a capacity of observation and a critical and scientific spirit.

The Theoretical Grade will be obtained through Final Theoretical Examination and/or tests during the semester.
It will be necessary to do three laboratory works (with previous preparation) and attend seven theoretical/practical lessons.
