Basic
CB1 - Students should have demonstrated knowledge and understanding in an area of study that parts from the basis of general secondary education, and is typically at a level that, whilst supported by advanced textbooks, includes some aspects involving knowledge of the forefront of their field of study.
CB2 - That the students can apply their knowledge to their work or vocation in a professional manner and have competences typically demonstrated through devising and sustaining arguments and solving problems within their field of study.
CB3 - Students should have the ability to gather and interpret relevant data (usually within their field of study) to inform judgments that include relevant social, scientific or ethical aspects.
CB4 - That students can communicate information, ideas, problems and solutions to both specialist and non- specialized audience.
General
CG3 - Knowledge in basic materials and technology, to enable them to learn new methods and theories, and equip them with versatility to adapt to new situations.
CG5 - Knowledge to perform measurements, calculations, valuations, appraisals, surveys, studies, reports, work plans, and similar work.
Specific
CE4 - Ability to understand and apply the principles of basic knowledge of general chemistry, organic and inorganic chemistry and their applications in engineering.
Transversal

A) Lectures
Lesson taught by the teacher who may have different formats (theory, problems and/or general examples, general guidelines on the matter ...). The recommended text will be used as reference. For each topic, transparencies, figures and diagrams that the teacher will use in their classes will be available to students in the virtual classroom of the subject. In addition, a list of exercises will be proposed in order for the students to apply their knowledge to solve problems.
B) Seminars
Theoretical/practical class in which applications of theory, problems, exercises, ... are proposed and solved. The student participates actively in these classes. The seminar sessions will be used for control testing in order to be able to monitor the level of student understanding.
C) Labs
The work will be done in pairs or in groups of three people. In these classes students acquire the basic skills needed in a chemistry laboratory and consolidate the knowledge acquired in the lectures. For these classes, the student will have in advance the scripts of all experiments, in order to be prepared before entering the laboratory. The student must attend each lab session knowing fully well the task to be performed. To do this, please carefully read the script for the experiment, consult the relevant literature and ask any questions to teachers. At the end of the sessions, the lab notebook containing the results of the measurements and proposed questions related to the experiments has to be submitted to the teacher for evaluation.
D) Tutorials
Two hours for each student, according to previously established and published schedule. These classes are used to work some non-specific aspects of the subject (errors in measurement, data processing, or others), but that are critical to the resolution of certain issues especially related to labs.

ATTENDANCE:
It is compulsory to attend practices and tutorials previous to labs, unless duly justified exceptional cause. Absences must be supported by documents, accepting examination and health reasons as well as cases falling within the existing university regulations.
EVALUATION OF FIRST-TIME STUDENTS:
The passing grade is obtained with a final score of 5 out of 10. The final grade of the student, both in the first and second opportunity will be based on the evaluation of the following aspects:
25% of the final mark: continuous assessment based on class participation, delivery of exercises, and the tests carried out in the seminars and tutorials. You must obtain a minimum grade of 4 out of 10 to pass the course.
Competencies evaluated: CB1, CB2, CG3, CE4, CT1.
15% of the final grade: Labs evaluation based on the continuous assessment during the experiments, the quality of the lab notebook, and a number of issues related to each experiment to be properly resolved by the student. You must obtain a minimum grade of 4 out of 10 to pass the course.
Competencies evaluated: CB3, CB4, CG3, CG5, CE4, CT1, CT4.
60% of the final grade: final examination of the subject with conceptual issues and problems. You must obtain a minimum grade of 4 out of 10 on the exam to pass the course.
Competencies evaluated: CB1, CB2, CE4, CT1.

EVALUATION OF SECOND-TIME STUDENTS:
The procedure for obtaining the final grade will be the same as for students of first registration. The contribution of the labs is in case they have been passed (5 out of 10) during the last two academic years, and in this case it is not compulsory to attend these activities. If a student asks to be evaluated again in these parts, he/she must meet the standards of students of first registration and the new mark will be used for the calculation of the final mark. In no case the mark from the final exam will be preserved.
Students who, because they belong to the previous curriculum, do not have the right to teach and have not approved the contributions of continuous assessment and/or labs, will perform on the scheduled exam date additional tests to evaluate said contributions, which will have the same weight that for the rest of the student body.

The number of classroom hours for this course amounts to 51 (excluding exams), so students should devote some 99 hours of personal work, divided between study on their own for the deepening of the theoretical contents and application of these contents to the resolution of problems and issues. Also, part of this time is spent on the preparation and resolution of issues related to the work done in the labs.
For each of the following activities the following work time is estimated:
Lectures 31 presential hours; 55 personal work.
Seminars: 3 presential hours; 10 personal work.
Tutorials: 2 presential hours, 2 personal work.
Labs: 15 presential hours, 12 personal work.
Final exam: 4 presential hours, 16 personal work.

• It is important to keep the study of the subject "on a daily basis".
• Once a topic is exposed, it is useful to summarize the important points, identifying the basic equations and making sure to comprehend both its meaning and the conditions under it can be applied.
• Problem solving is central to learning this subject. It may be helpful to follow these steps: (1) Make a list of all relevant information provided by the statement (2) Make a list of the magnitudes to be calculated and if possible an outline of the relevant data and information sought. (3) Identify the equations to use in solving the problem and apply them correctly.
• It is essential the preparation of experiments before entering the laboratory. First, you should review the important theoretical concepts in each experiment and then, you need to carefully read the script, trying to understand the objectives and the development of the proposed experiment. Any doubt that might arise must be discussed with the teacher.
• It is recommended to regularly consult the virtual classroom for the course, which will made available the teaching guide of the subject, lab scripts, problem sets and solutions, and other supplementary material to help students in their study (slides, web links, etc.). In addition, delivery activities and ongoing assessment will be managed through the virtual classroom.

The classes are given in Galician.


In cases of fraudulent performance of exercises or tests, the procedures contained in the "Regulations for evaluating student academic performance and reviewing grades" will be applied.
