General description Na materia "Química: Equilibrio e Cambio", do primeiro curso da titulación de Grao en Nanociencia e Nanotecnoloxía estúdanse os fundamentos da termoquímica, os aspectos máis relevantes dos equilibrios químicos en disolución e superficie, as bases da cinética química, etc. Preparando ao alumnado para o estudo dos fenómenos de equilibrio e da reactividade química.
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, se adaptarán 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, se utilizarán 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 alumando. 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.

Methodologies
Methodologies Description
Guest lecture / keynote speech The teacher will develop the fundamental contents of each topics through theoretical explanations and practical examples. For better learning, students will have the appropriate teaching materials in advance for their personal preparation on the subject's website (Moodle). Students' participation will be encouraged. It will be taught in a large group.
Seminar Sessions dedicated to the analysis and resolution of problems and questions with the active participation of students and teachers. It will be given in small groups. The bulletins to be solved will be found on the website of the subject (Moodle) before the students work prior to the seminar.
Laboratory practice In the laboratory sessions (in small group) the student will develop experimental examples of the theoretical contents exposed in the classroom. It will be fundamental to carry out the pre-laboratories before doing the corresponding practice (if not, the student will not be able to do it), as well as to update the laboratory notebook, according to the teacher's indications. An initial session will be given in the classroom (large group) to expose the students to the contents and dynamics of the practices.
Objective test Periodically, short tests will be carried out in the guest lectures or seminars 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 have to take a mixed objective/subjective test of the whole subject that allows to evaluate the degree of acquisition of knowledge and competences by the students. It will include questions and problems about the contents of the whole subject that will have to be solved in a reasoned way.

Description
When the teachers consider it necessary, they may call the students to individualized tutorials to guide them in relation to their evolution in the subject, establishing the schedule in accordance with them.
Students may also request tutorials with the teaching staff, who will resolve any doubts they may have and guide them in the study of the subject.

Objective test A1 A2 A3 A7 B1 B2 B3 B7 C1 Periodically, short tests will be carried out in which students 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. 20
Seminar A1 A2 A3 A7 B1 B2 B3 B6 B7 B8 B9 C1 C2 C3 C6 The resolution of questions and/or problems bulletins, the fulfilment of dates for their delivery or revision and also the participation of the students through the raising of questions before or after the development of the seminars will be valued.

Laboratory practice A1 A2 A3 A7 A8 B1 B2 B3 B6 B7 B8 B9 C1 C3 C6 The completion of the laboratory practices is mandatory in order to pass the course. The performance of the pre-laboratories, the capacities and skills of the student in the performance of the experimental work, his capacity to interpret the results obtained, the elaboration of the laboratory diary, etc. will be valued. 15
Mixed objective/subjective test A1 A2 A3 A7 B1 B2 B3 B7 B8 C1 The mixed test shall consist of the resolution of problems and questions relating to the whole contents of the subject. This final test will be held on the official dates agreed at the Centre. 60
 
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 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).


-Students who do not participate in the seminars activities and do not realize
the objetive tests will score 0 in these sections (5% and 20%, respectively, of
the overall grade). In the second opportunity, these grades will be maintained
for the overall rating.

-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.

- 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..
