Prerequisites
There are no official prerequisites. However, it is assumed that the student has acquired the basic knowledge taught in the Chemistry and Technology and / or Experimental subjects of the baccalaureate.
Objectives and Contextualisation
In the subject Chemistry, concepts in the Inorganic Chemistry area, such as the atomic structure, the periodic table and the chemical bond, are studied in a first part, introducing the concept of Stoichiometry of compounds and reactions . We continue talking about the aggregation states of the matter, emphasizing dissolutions. Concepts of thermodynamics and chemical kinetics are introduced. In a second part, the section of dissolutions is extended by talking about the concept of chemical equilibrium, in the area of Analytical Chemistry, mentioning the main balances to be considered in aqueous solution. Finally, the last part of the subject will refer to a brief introduction to Organic Chemistry and Stereochemistry.

Content
THEORY
The first topics (1 to 4) try to review the previously acquired concepts, between ESO and Baccalaureate.
Topic 5 includes chemical equilibria in dissolution, the basis for understanding many of the chemical and biochemical processes in our environment, so it will be an extensive subject, with much of the applied exercises.
Item 6 is a review of organic formulation and nomenclature, extending information relative to the main characteristics of the various types of compounds.
Topic 1. Fundamental concepts: matter, substance and mixture; physical-chemical properties; elements and compounds.
Topic 2. The periodic table. Chemical equations
Subject 3. Chemical link.
Topic 4. Thermodynamic and kinetic bases of balance.
Topic 5. Acid-base equilibria. pH and alkalinity. Oxidation-reduction balances. Solubility balances.
Topic 6. Structures and formulas of organic molecules. Aliphatic and aromatic hydrocarbons. Alcohols, ethers and thiols. The carbonyl group: aldehydes and ketones. The carboxyl group: acids and derivatives. The amino group and derivatives. Organic compounds and toxicity.
PROBLEMS
The content of this section, which will be presented in the form of a dossier at the beginning of the semester, consists of a certain amount of statements of problems related to the topics developed in Theory. The characteristics of the different parts of the Theory's agenda make the statements of these problems concentrate on certain aspects that are: calculations of concentration of dissolution (concentration concept and way of expressing it), conversion factors, and stoichiometric calculations. In the Chemical Balance section, exercises will be related to learn to perform pH calculations of acid-base solutions, determine the presence of soluble coordination compounds (complexation equilibria), determine the oxidizing or reducing capacity in Aqueous solutions (oxidation-reduction equilibrium) as well as determine the solubility of insoluble salts (solubility equilibria) including fractional precipitation concepts (separations of spices). Finally, problems of formulation and nomenclature of organic chemistry will be included in the collection.
LABORATORY PRACTICES
There are two laboratory sessions of four hours each.
Practice 1: SEPARATION AND PURIFICATION OF SOLIDS
Practice 2: DETERMINATION OF THE DURATION OF WATER. DETERMINATION OF CALCIUM AND MAGNESI IN WOMEN OF DOMESTIC CONSUMPTION
*Unless the requirements enforced by the health authorities demand a prioritization or reduction of these contents.
Methodology
The training activities are divided into three sections: theory classes, problem classes and laboratory practices, each one with its specific methodology. These activities will be complemented by a series of tutoring sessions that will be programmed additionally.
Theory classes
The teacher will explain the content of the syllabus with the support of audiovisual material that will be available to students in the Virtual Campus of the subject. These lectures will be the most important part of the theory section.
Under the guidance of the teacher and through communication through the Virtual Campus, the knowledge of selected parts of the syllabus will have to be searched and studied by means of autonomous learning by the students. In order to facilitate this task, information about locations will be provided in textbooks, web pages, etc. This material of autonomous study and other questions / practical problems that may be raised will be, in part, the content of the tutorial sessions.
Also to reinforce learning, cooperative activities will be proposed to be carried out in groups, both inside and outside the classroom. Within the classroom they will be led by the teacher, in some kind of theory. And activities outside the classroom will involve the need to do bibliographic research, as well as to organize properly for teamwork, discussion and sharing of the knowledge acquired by each member of the group.
Problem classes
The group will be divided into two subgroups, whose lists will be made public at the beginning of the year. Students will attend the sessions programmed by their group.
At the beginning of the semester a dossier of statements of problems of the subject will be delivered through the Virtual Campus that will be resolved throughout the sessions. In these sessions distributed throughout the semester, the teacher of problems will present the experimental and calculation principles necessary to work on the problems, explaining the guidelines for their resolution and reinforcing the same time the knowledge of different parts of the subject of the theory classes .
Laboratory practices
The group will be subdivided into two subgroups, whose lists will be announced in advance. It is necessary to appear in practices with a lab coat, the practice protocol (available on the Virtual Campus) printed, and previously read. It will also be necessary to carry a notebook to record the observations made and the data obtained.
On the days set in the calendar, students will be summoned to the chemistry laboratory to carry out basic experiences. The practices will be carried out in pairs, while being evaluated individually. At the end of each session, a test type questionnaire will be required to evaluate the understanding of the related practice, and will present the results of the experiment. Attendance is mandatory.
Tutorials
The schedule of individualized tutorials will be specified with the teacher. If the teacher finds it appropriate in some cases they will do group tutorials in the classroom, at agreed times.

Assessment
The evaluation of the subject will be carried out by means of a continuous evaluation that will consist of:
1) Carrying out a certain number of cooperative activities in small groups of students. A minimum of 40% of this grade must be obtained for it to count in the final grade, otherwise the subject will be suspended. The average grade for these cooperative activities is 30% of the final grade.
2) Two individual partial tests, corresponding to approximately two halves of the syllabus. They will be tests that will eliminate matter, that is to say, the first test will evaluate the first part of the syllabus, and the second test will evaluate the second part of the syllabus. A minimum of 40% must be obtained in both partial tests so that the mark of these counts in the final mark, otherwise the two partial tests are replaced by a final test that will evaluate the syllabus of the whole course. Each partial test corresponds to 30% of the final grade.
3) A final test of the same format as the partial tests: theory and numerical exercises. This final test replaces the two partials together, ie it is used for those students who have not passed one or neither of the two partials (they have not taken more than 4 each of both partials). In all cases, the previous notes corresponding to the partial ones will be invalidated. A minimum of 40% must be obtained in this test to be counted in the final grade, otherwise the subject will be suspended. This final test corresponds to 60% of the final grade.
4) Each of the laboratory practices will be evaluated by means of a questionnaire and / or report of each practice. The mark of this part will be given by the average mark of the practices, taking into account the questionnaires and / or reports, the attitude in the laboratory and the revision of the laboratory notebook. A minimum of 40% of this grade must be obtained for it to count in the final grade, otherwise the subject will be suspended. The average grade for these internships is 10% of the final grade.
To participate in the recovery, students must have previously been assessed in a set of activities whose weight is equivalent to a minimum of two thirds of the total grade of the subject. Therefore, students will obtain the grade of "Non-Assessable" when the assessment activities performed have a weighting of less than 67% in the final grade.
*Student’s assessment may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.
