Teaching Methodologies and Assessment Criteria |
The transmission of the syllabus is done mainly through oral presentation, complemented with
Audiovisual.
Carrying out laboratory experiments, as well as the preparation of the respective reports, and the resolution of exercises on the topics
developed in class are essential for students to be able to perform the calculations necessary to discuss the results
obtained in chemical analyses.
