Prerequisites

Although there are no official prerequisites, it is appropriate that the student has achieved:

    1) Some basic concepts of Chemistry of the baccalaureate: stoichiometry, dissolutions and chemical equilibrium.

    2) The knowledge of Chemistry that has been acquired in the "Chemistry I" taught in the first semester.

Objectives

The Chemical II subject in the degree.

This is a first-cycle subject, basic training, which reinforces the basic fundamentals of general chemistry that the student has, introduces the concept of analytical process and develops the main techniques of chemical, classical and instrumental analysis. These knowledge and skills will be very necessary for the student in subjects of subsequent courses where they develop in depth the methodologies of analysis of foods.

The laboratory practices related to this subject (classical and instrumental chemical analysis) will be carried out in the subject "Experimentation in the laboratory".

Learning outcomes

The development of the course is based on the following activities:

1) Theoretical classes (classroom)

The student acquires the own scientific knowledge of the subject attending the theoretical classes and complementing them with the personal study. The theoretical classes can be expositivas and classes of work individual or in group; The first activities are conceived as a fundamentally unidirectional method of transmitting the knowledge of the teacher to the student, while the latter involve a teacher-pupil interaction, and will count on the continuous assessment note.

2) Classroom practices (problems and seminars)

In the problem classes the scientific knowledge is worked on from the resolution of problems and / or practical cases. In these classes there must be a strong interaction between students and teachers in order to complete and deepen the understanding of the knowledge worked in the theoretical classes.


In the seminar classes the student works individually or in a group solving exercises and / or questions raised in the same class or in advance.

The sessions of problems and seminars should also serve as a solution to doubts and deepen certain key concepts of the subject.

Some of these activities will count for the continuous evaluation note.

The commission of any irregularity in an assessment activity (academic fraud, plagiarism, or misuse of AI, unless such use is expressly authorized in the teaching guide) that could lead to a significant change in the grade will result in a grade of 0 for that activity. If the teaching guide specifies that achieving a minimum grade in that assessment activity is a mandatory requirement to pass the subject, or if multiple irregularities occur in the assessment activities of the same subject, the final grade for the subject will be 0. Additionally, disciplinary proceedings may be initiated against any student who commits such irregularities.

In this subject, the use of Artificial Intelligence (AI) technologies is permitted as an integral part of the development of the work, provided that the final result reflects a significant contribution from the student in terms of analysis and personal reflection. The student must clearly identify which parts have been generated using this technology, specify the tools used, and include a critical reflection on how these have influenced the process and the final outcome of the activity. A lack of transparency regarding the use of AI will be considered academic dishonesty and may lead to a grade penalty for the activity, or more severe sanctions in serious cases.

The commission of any irregularity in an assessment activity (academic fraud, plagiarism, or misuse of AI, unless such use is expressly authorized in the teaching guide) that could lead to a significant change in the grade will result in a grade of 0 for that activity. If the teaching guide specifies that achieving a minimum grade in that assessment activity is a mandatory requirement to pass the subject, or if multiple irregularities occur in the assessment activities of the same subject, the final grade for the subject will be 0. Additionally, disciplinary proceedings may be initiated against any student who commits such irregularities.

Annotation: within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
Evidence of learning 30 10 0.4 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15
Control of block I and II 35 2 0.08 3, 4, 5, 6, 7, 8, 9, 10, 15
Control of block III 35 2 0.08 3, 11, 12, 13, 14

Continuous evaluation

The competences of this subject will be evaluated by means of:

   a) A control of the blocks I and II (individual), with a weight of 35% of the final mark.

   b) A control of block III (individual), with a weight of 35% in the final note.

   c) Evidence of learning. Individual or group activities carried out in theory classes or classroom practices (problems or seminars), or out of the classroom. Overall, we will have a weight of 30% in the final note.

  

To approve the subject, it is asked:

  a) A minimum of 3.5 points (out of 10) in each of the two controls; If you do not arrive at this note you will have to present yourself to the corresponding recovery test. To pass the subject, you must have a minimum of 3.5 points in each control once the recovery is completed.

  b) A minimum of 5 points (over 10) in the average of the controls and the learning evidences, according to the weighting established previously.

 

It will be considered that a student is not evaluable if he has participated in assessment activities that represent ≤ 15% of the final grade.

 

Single evaluation

Within  the regulatory period established by the University, students may request the single evaluation, renouncing the continuous evaluation.

 

The single evaluation will consist  of a synthesis exam, with a weight of 100% of the final grade. The exam will have two parts:

Part 1. Conceptual questions and resolution of numerical exercises of blocks I and II. It will have a weight of 50% in the final grade. You must obtain a minimum of 3.5 (out of 10) to pass the subject.

Part 2. Conceptual questions and resolution of numerical exercises of block III. It will have a weight of 50% in the final grade. You must obtain a minimum of 3.5 (out of 10) to pass the subject.

 

To pass the subject, a minimum grade of 3.5 must be obtained in each part, and a minimum final grade of 5 points (out of 10) in the synthesis test.

 

In the case of failing this synthesis exam, students may take a recovery exam for the entire course (blocks I, II and III). This exam will have the same parts as the single synthesis test and the same requirements will be asked to pass.

These synthesis and recovery tests will coincide with the dates of the 2nd partial and recovery exams of the students who opt for continuous evaluation.

It will be considered that a student is not evaluable if he does not appear in the synthesis exam or, if he takes it, in the recovery exam.
