General description A materia Química Xeral 3 pertence ao módulo de Química, do primeiro curso da titulación de Grao en Química. Nela estúdanse os aspectos máis relevantes dos equilibrios químicos en disolución, que constitúen a base de numerosos procesos da química inorgánica, orgánica, analítica e química física.
Contingency plan 1. Modificacións nos contidos
Non se realizarán cambios.
2. Metodoloxías
*Metodoloxías docentes que se manteñen
Manteñense todas as metodoloxías e se a situación sanitaria o require, adaptarasen ao modo non presencial a través da aula virtual Moodle e Teams.
No caso de que parte do alumnado non poida conectarse e seguir as clases en tempo real, utilizaranse medios asíncronos (correo electrónico, grabacións das sesións expositivas, tutoriais máis personalizados ...).

*Metodoloxías docentes que se modifican
Non hai modificacións.

3. Mecanismos de atención personalizada ao alumnado
– Correo electrónico: Diariamente. De uso para facer consultas, solicitar encontros virtuais para resolver dúbidas, etc.
– Moodle: Diariamente. Segundo a necesidade do alumnado. Dispoñen de “foros temáticos” da materia, para formular as consultas necesarias e postas en común.
– Teams: sesións maxistrais (en grupo grande) e seminarios e prácticas (en grupo pequeno) para o avance dos contidos teóricos e aplicados da materia, na franxa horaria que ten asignada no calendario coordinado do título.

4. Modificacións na avaliación
Non se realizan cambios.
*Observacións de avaliación:
Manteñense as observacións á avaliación.Todas as actividades avaliables levaranse a cabo a través dos medios telemáticos máis axeitados en cada caso (Teams, Moodle, etc.).
O alumnado que non poida seguir actividades sincrónicas en líña serán evaluados por actividades equivalentes realizadas de forma asíncrona.

5. Modificacións da bibliografía ou webgrafía
Non se realizarán cambios. Xa dispoñen de todos os materiais de traballo da maneira

Methodologies
Methodologies Description
Guest lecture / keynote speech The teacher will present the fundamental contents of each of the topics. For better learning, students will have to advance the development of these sessions teaching materials suitable for your personal preparation. All students can consult the teacher any aspect of the matter in the tutorial schedule established for this purpose. He taught in large group.
Seminar Sessions devoted to the resolution of problems and issues with the active participation of students. He taught in small group.
Laboratory practice In the laboratory sessions students will develop experimental examples of the theoretical exposed in the classroom. Will be essential to achieving the prelaboratorios before the relevant practice (but the student can not perform such practice) as well as keep up to date lab book, according to the instructions of the teacher. This will be carried out in small group. An initial meeting will be provided in large group students to explain the content and dynamics of practices.
Objective test Periodically, in the guest lecture, in the seminars and/or in the Moodle virtual classroom, short tests will be carried out to evaluate the degree of acquisition of knowledge and skills by the students and to promote continuous assessment throughout the course.
Mixed objective/subjective test The student will perform a joint test for verifying the degree of understanding and skills of the subject has gained. It will include questions and problems about the contents of the whole subject that will have to be solved in a reasoned way.

Laboratory practice
Seminar
Description
Students will be invited to two 1-hour sessions of personalised attention to resolve any possible doubts and to provide guidance on the contents of the course.

Students may also request tutorials with the teaching staff, who will resolve any doubts they may have and guide them through the study of the subject.


Assessment
Methodologies Competencies Description Qualification
Laboratory practice A7 A12 A16 A17 A19 A20 A23 B3 B4 B5 C1 C3 It will assess the performance of the prelaboratorios, abilities and skills of students in the experimental work, their ability to interpret the results, etc. 20
Seminar A1 A5 A6 A21 A25 B2 B3 B4 B5 C3 It will be valued the resolution of questions and/or problems, compliance dates for delivery or revision and also the participation of the student through the raising of questions, before or after the development of the seminars. 5
Mixed objective/subjective test A1 A4 A5 A6 A12 A20 A21 A25 B3 C1 It has two parts. In one of them will be evaluated the student's ability to express, summarize and develop theoretical aspects of the subject and, in the other, the resolution of problems and numerical exercises. 60
Objective test A1 A4 A5 A6 A12 A20 A21 A25 B3 C1 Periodically, short tests will be carried out in which students must answer questions or solve problems in a reasoned manner that allows them to evaluate their degree of understanding of the most important aspects of the subject. 15
 
Assessment comments

-To pass the subject you must:

   1) Perform the laboratory practices.

   2) Obtain a higher or equal to 5 points rating (out of 10) in the laboratory practices and in each part of the mixed test. If the total sum value was
equal to or greater than 5 (out of 10) but this threshold mark was not met, the
final mark will be 4.5 (fail).

-In the first and second time, students who do practices and obtain less than 5, have the opportunity to, in addition to the mixed test, perform a specific test related to the labs. The score of this test especcífica replaced the grade obtained in practice for the overall rating.


-Students who do not participate in the seminars activities and do not realize the objetive tests will score 0 in these sections (5% and 15%, respectively, of the overall grade). In the second opportunity, these grades will be maintained for the overall rating.

-
The student will obtain the qualification of No Presented when the
student does not assist to the laboratory practice and neither attend to
the mixed test. As regards the successive academic years, the teaching-learning process, including continuous assessment, refers to an academic course and, therefore, would comezar a new course, including all activities and procedures the Assessment that is scheduled for that course.

- Second Opportunity: The mixed test's mark obtained in the second opportunity  will replace the first one's. The students tested on the second occasion shall be eligible for honors if the maximum number of these to the corresponding course not covered in full at the first opportunity.

Students with recognition of dedication and part-time academic exemption waiver assistance:

Conducting laboratory practices are mandatory and it will be provided within the flexibility to allow coordinating schedules and material and human resources. They shall be deemed exempt from the keynote sessions while assistance will be provided to the greatest number of seminars. If they can not attend the seminars will make a mentored work.

Other comments

To successfully overcome the matter, it is imperative that students have a number of prior knowledge of chemistry and mathematics, according to the level required in middle and high school, including: nomenclature and chemical formula, set of chemical reactions , stoichiometric calculations, acid-base character identification of common compounds, obtaining oxidation states of the elements in the chemical species, management of logarithms, exponents, etc..
