Prerequisites
General knowledge of Chemistry.
Objectives
1. To assimilate the most important changes that the world of chemistry is experiencing in recent years in order to minimize its environmental impacts and achieve more sustainable modern societies. Green Chemistry.
2. To take a tour of the most notable cases of replacement of non-renewable, toxic, and dangerous materials with more sustainable alternatives.
3. To recognize the role of chemistry in the development of renewable energies.
4. To mention some particular issues of improvement in chemical processes and materials that have a decisive impact on sustainability on the planet.

Assessment
Continuous assessment activities
| Title | Weight | Hours | ECTS | Learning outcomes |
|---|---|---|---|---|
| Homeworks | 10% | 10 | 0.4 | CM37, CM39, KM47, SM46 |
| Two written tests with theoretical and practical parts | 90% | 6 | 0.24 | CM37, CM39, KM47 |
Continuous assessment:
1st Partial: 45% of the final grade
2nd Partial: 45% of the final grade
1st Assignment: 5% of the final grade
2nd Assignment: 5% of the final grade
Second Chance Exam: 90% of the grade. The remaining 10% will be the grade for the assignments. The Second Chance exam will be for each partial.
The midterm exams will consist of multiple-choice questions and questions requiring students to develop reasoning skills.
A minimum final grade of 5.0 is required to pass.
Failure to participate in any of the activities will result in a grade of zero.
If neither of the two written exams is taken, the final grade will be "Not Assessable."
To participate in the resit exams, students must have been previously assessed on a set of activities that account for at least 60% of the total grade for the course (either one of the midterm exams and both individual assignments, or both midterm exams). If a student has not been assessed on at least 60% of the assessments, they will receive a grade of "Not Assessable."
The commission of any irregularity in an assessment act (academic fraud, plagiarism or improper use of AI, unless this use is expressly authorized in the teaching guide), which may lead to a significant variation in the grade, means that this act will be graded with a 0. In the event that the teaching guide provides that in order to pass the subject it is an essential requirement to have obtained a minimum grade in this assessment act or that several irregularities occur in the assessment acts of the same subject, the final grade for this subject is 0. Apart from this, a disciplinary process may be initiated against the student who incurs any of these irregularities.
Single assessment:
Students who have opted for the single assessment method must take a final test that will consist of a theory exam where they must answer a series of short questions and develop a couple of topics. When finished, they will submit the practice reports.
The student's grade will be the weighted average of the previous activities, where the theory exam will account for 80% of the grade, and each of the practice reports 10% (1st and 2nd papers).
If the final grade does not reach 5, the student has another opportunity to pass the subject through the remedial exam that will be held on the date set by the degree coordination. In this test, 70% of the grade corresponding to the theory can be recovered. The practice part is not recoverable.
Use of AI
Restricted use: For this subject, the use of Artificial Intelligence (AI) technologies is permitted exclusively in support tasks, such as bibliographic or information searches, text correction or translations,... 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, or greater sanctions in serious cases.
