Prerequisites
Although there are no official prerequisites, it is highly advisable that the student has taken chemistry during high school.
Objectives
The general objective of the subject is to arouse in the student an interest in the phenomena of nature that are in the field of chemistry, that is: the study of matter from an atomistic point of view, and the awareness that this study is based on the general laws of the physical world.
At the same time, it is also intended that the knowledge acquired will allow the student to broaden their field of vision, and therefore, their job possibilities.
Partial objectives of the subject are:
1) Understand the nature of the chemical bond and how the molecular structure allows us to rationalize the intermolecular interactions that lead to the existence of different states of matter.
2) Understand the basic concepts of chemical kinetics and chemical equilibrium, and know how to apply them in real examples.
Learning outcomes

Learning activities and methodology

| Learning results | 140 | 5.6 | CM07, CM08, KM06, KM07, KM08, SM04, SM05, SM06 |
The center of the learning process is the work of the students. They learn by working, and the mission of the teachers is to help them in this task (1) by providing them with information or showing them the sources where it can be obtained and (2) by accompanying their steps so that the learning process can be carried out effectively. In line with these ideas, and in accordance with the objectives of the subject, the development of the course is based on the following activities:
Theoretical classes:
Students acquire the scientific and technical knowledge specific to the subject by attending classes and participating in the construction of their own knowledge. In these, explanations by the teachers will alternate with the raising of questions and discussion among the students. To complement them, personal study of the topics worked on is necessary.
Problem classes, exercises and seminars:
In these sessions, with a double mission, on the one hand, the scientific-technical concepts previously worked on in the theoretical classes are worked on to complete their understanding and delve into them basically based on the resolution of problems. On the other hand, based on the critical discussion of the exercises carried out, these classes are the natural forum in which to discuss together the development of the work done by the students, providing the necessary knowledge to carry it forward, or indicating where and how it can be acquired. The mission of the problem classes and seminars is to act as a bridge between the theoretical classes and independent work, promoting the capacity for analysis and synthesis, critical reasoning, and the capacity for problem resolution.
Note: 15 minutes of a class will be reserved, within the calendar established by the center/degree, for students to complete the surveys to evaluate the performance of the teaching staff and to evaluate the subject/module.
Assessment
Continuous assessment activities
| Title | Weight | Hours | ECTS | Learning outcomes |
|---|---|---|---|---|
| Sesiones de teoría y problemas | 100% | 10 | 0.4 | CM07, CM08, KM06, KM07, KM08, SM04, SM05, SM06 |
This subject will be subject to continuous assessment. The final grade will be distributed among the following concepts:
- Follow-up evidences (15% weight, non-retrievable)
- 2 Midterm Exams (P1 and P2, 85% weight altogether)
To pass the subject, the weighted average of the two midterm exams and the follow-up evidences (short individual tests and group presentation of a proposed subject) will be taken and the grade obtained must be at least 5.0. In addition, a minimum of 4.0 is required in each of the two midterms P1 and P2.
- Final retake exam (85% weight). Optional and includes all the subject material, with the aim of retaking the subject or raising the final grade of the subject. The grade of the final exam will replace the grade that could have been obtained from the two midterms together. It should be noted that only 85% of the subject can be retaken, corresponding to the grade of the midterm exams. The grade for the follow-up evidences (15% weight) cannot be recovered. To take the final exam, students must have previously taken at least 1 of the 2 partial exams.
If the retake exam grade does not exceed 4.0, the course average may not be higher than 4.5 in any case.
Those not assessed
Students will be considered to obtain the grade of “Not assessable” if they have not taken all the partial exams or the final exam.
SINGLE EVALUATION
Students who have taken advantage of the single evaluation modality must take a final global test for the subject that will be held on the same day, time and place as the test for the second partial of the continuous evaluation modality. The final grade for the subject will be the one obtained from this final test since the continuous evaluation evidences will not have been taken.
If the grade is lower than 5.0 out of 10, the student will have another opportunity to pass the subject through the retake exam that will be held on the date set by the degree coordination (same day as the retake exam for students whofollow continuous assessment).
Use of AI:
For this subject, the use of Artificial Intelligence (AI) technologies is permitted exclusively in the preparation of the group presentation. The student must clearly identify which parts have been generated with this technology, specify the tools used and include a critical reflection on how these have influenced the process and the final result of the activity. The lack of transparency in the use of AI in this assessable activity will be considered a lack of academic honesty and may lead to a partial or total penalty in the grade of the activity.
