Chemistry B


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.

Teaching method


In the theoretical classes, the concepts to be retained will be presented and explained in an interactive and proactive way. In the theoretical-practical classes, topics will be discussed and problems that require the application of the knowledge learned will be solved.

In practical laboratory classes, experiments will be carried out directly related to the topics taught and discussed and the results will be criticized.

Evaluation components

Two tests that address the knowledge of the curricular unit, replacing it with an exam.

Participation in theoretical classes and problem solving during theoretical-practical classes.

Performance and discussion of the experimental results achieved during the practical sessions.

Evaluation method

• Attendance (presence in classes) is mandatory to be evaluated.
Frequency is achieved by attending online sessions.

The maximum number of absences allowed is that stated in the current legislation.

• The final evaluation results from the application of the following calculation formula:
• Final grade (must be greater than or equal to 9.5 values for approval in the course) = average of two tests (or final exam) * x 0.60+ grade obtained in theoretical sessions x 0.10 + grade obtained in theoretical-practical sessions x 0.15 + grade obtained in practical sessions x 0.15

• * the grade obtained in the average of the two tests or in the final exam must be 9.5 or higher. (tests without individual minimum score)

Students who have acquired frequency in previous years will see the theoretical-practical (TP) and laboratory (P) component replaced by that registered note, which will have a weight of 0.40 in the final note.
