General description Esta materia enmárcase no módulo de Química, 1º curso da titulación de Grao en Química. É continuación natural da asignatura "Química 1", amosando cómo os conceptos alí estudados a nivel atómico e molecular se expresan en termos macroscópicos. Así, estúdanse os fundamentos da termoquímica, estados de agregación, cambios de fase, mezclas e disolucións, bases da cinética química, etc.
Esta asignatura prepara ao alumno para o estudo dos fenómenos de equilibrio, así como dos cambios físicos que pode sufrir a materia, e da reactividade química.
Contingency plan 1. Modificación dos contidos. No se realizan cambios.
2. Metodoloxías. Ao tratarse dunha materia do segundo cuadrimestre pódense dar tres situacións diferentes: (A) docencia presencial total, si o acceso ao centro estivera permitido en horario e aforo sen restricións; (B) docencia presencial híbrida, si o acceso ao centro estivera restrinxido en horario e aforo; (C) docencia non presencial, si o acceso ao centro estivera totalmente prohibido. Neste último caso (C), a docencia sería totalmente non presencial.
* Metodoloxías docente que se manteñen. Na situación (A) mantéñense todas.
* Metodoloxías docentes que se modifican. Na situación (B) as clases maxistrais impartiranse de xeito presencial rotatorio (aforo presencial limitado), ao mesmo tempo que se retransmiten as clases síncronamente mediante MS Teams; os grupos reducidos seguirían a ser presenciais e as prácticas seguirían a ser presenciais, mais haberá que controlar o aforo do laboratorio, podendo ser necesario impartir parte das prácticas online con materiais creados polos profesores. Na situación (C), clases maxistrais, grupos reducidos e prácticas desenvolveranse totalmente online.
3. Mecanismos de atención personalizada ao alumnado. Correo electrónico, titorías por Teams e foros en Moodle, con atención diaria no caso de correo electrónico e foros, e previa petición do alumnado no caso das titorías por Teams.
4. Modificacións na avaliación. Nas situacións (A) e (B), non se modifica nada, a proba mixta será presencial. Na situación (C), a avaliación será non presencial online.
*Observación de avaliación: en todas a situacións manténense as mesmas que figuran na guía docente.
5. Modificacións da bibliografía ou webgrafía. Na situacións (A) e (B) ningunha; na situación (C), engadiranse en moodle enlaces a libros dispoñibles en formato electrónico que puideran ser de libre acceso para todos os estudantes.

Methodologies
Methodologies Description
Guest lecture / keynote speech In the guest lectures the main features of the subject will be describe, as well as the basic contents.
Seminar In the seminars the contents will be stressed in the most detail, reinforcing the concepts covered in the lectures, mainly through the resolution of questions, problems and casework.
The seminar sessions will be based on the work of the students, which will be stated as the subject evolves.
For an adequate use of the seminars, the work will be indicated in advance to the students who should be done in advance of each seminar session.
Laboratory practice The practical demonstrations will develop experimental examples of the concepts discussed in the course.
The attendance to practical sessions is compulsory to pass the course as a whole.
Students, as indicated by the teachers, must fill a laboratory notebook. They must submit the notebook at a prefixed date. Apart from justified exceptions, notebooks will not be evaluated when delivered after the deadline.
Mixed objective/subjective test It includes open questions, key problems, and multiple choice, multiple answer, ordering, short answer, discrimination, completion and/or association exercises.

Description
In tutorials with students the learning process progress will be checked with reference to the different teaching methodologies planned.
Teachers will be available to students to solve any type of questions on the subject in tutorials established.
Part-time students and those with special academic leave permission could ask for presential or email tutorials when necessary anytime they need them.

Assessment
Methodologies Competencies Description Qualification
Seminar A1 A4 A5 A10 A12 A14 A21 B2 Students must work before hand the contents treated in the seminar. They must also work on these contents after these sessions. They have to paid attention during the seminars and concentrate on the concepts been analysed.
Students' work would be evaluated through short questions or problem solving performed sporadically.
10
Laboratory practice A3 A5 A14 A16 A23 A24 B3 B4 C1 C3 C6 The laboratory work of the student will be considered, including the plannig of experiments and their development, the critical analysis of the results obtained, the ability to extract generalisations and obtain conclusions, etc. At the same time, skills such as initiative, communication etc, will have take into consideration. Also the quality of the work performed will be evaluated.
Students must fill a lab book following teachers' indications. This lab book will be delivered before the fixed deadline. Only in exceptional, justified situations, lab books delivered after the deadline will be considered.
20
Mixed objective/subjective test A1 A3 A4 A5 A10 A12 A14 A21 B2 B3 Every student must do a test where their problem solving ability will be evaluated. Also concepts and short description capabilities will be evaluated. Time allocated to do this test will be indicated at the beginning of it.
Assessment will consider the knowledge reflected in this test, but also the quality of the results obtained.

Assessment comments

*Attendance to practical demonstrations is mandatory to successfully pass the subject.

*A final mark of at least 5 out of 10 (3.5 out of 7) is required in the mixed objective/subjective test. This mark will be added to the other evaluated methodologies to get the final mark.

* To pass the course, the final qualification has to be equal to or greater than 5 (out of a possible 10).  If the addition of all the marks obtained in the course is equal to or greater than 5 (out of 10), but the mark achieved in the mixed objective/subjective test is less than 5, the final qualification in the subject will be 4.5 (fail).

* Any student who has attended the practical sessions or the final exam will be assessed.

* According to the rules contained in “Probas de Avaliación e Actas de Cualificación de Grao e Mestrado”, the so-called “second opportunity of July” is understood as a second opportunity to retake the final written exam. The mark of  this second exam will be considered together with the others obtained during the course, corresponding to the other activities. The
percentages of the different contributions will be the same as those of the former "first opportunity".

* Mark Honors: priority is given in the first opportunity (January). Honors may only be granted in July if their number have not be exhausted in January final qualifications.

Part-time students:

The same evaluation criteria listed above are applied.

Students with special academic permission (according to the rules of the UDC):

The same evaluation criteria listed above are applied, but it´s not mandatory the attendance to the classroom lectures and seminars.

It is compulsory to attend computer practical sessions. It will be tried to fit the dates to the student's availability.

The final grade will be the sum of 20% of the mark obtained in the
practical sessions and 80% of the mark obtained in the mixed test. The same criteria will be applied to both opportunities.

Students who has not attended the final exam will be assessed as "non attendance".
