Objectives
The course "Química II" is for the Chemistry and Biochemistry B.Sc's. The main objective is to provide a solid understanding of the essential chemistry concepts necessary for further applications in other more specialized courses and multidisciplinary courses.
The main topics covered are Chemical Kinetics, Chemical Equilibrium, Acid-Base, Entropy, Gibbs energy, Electrochemistry, Metals and Transition Metal Chemistry.
Learning outcomes and competences
Ability to apply concepts acquired in practical situations. Ability to analyze simple chemical situations and select the necessary tools to obtain additional chemical information.
The main objective is that the students will be able to identify and interpret simple problems in general chemistry. The presentation and discussion of the topics in the theoretical classes followed by classes where the students solve problems with the assistance of the professor allows them to acquire the necessary knowledge and problem solving skills.

Teaching methods and learning activities
Teorethical classes are essentially lectures. The support materials are available to students in the course platform.
A set of issues/problems are discussed/solved in the theoretical-practical classes.
All classes will be online, until further notice.

Eligibility for exams
All the students that, due to lack of infrastructures/equipment or due to health problems, cannot attend online classes, should contact one of the professors of the course, in order to find an alternative way of learning.
Calculation formula of final grade
The continuous evaluation will include 5 tests: T1-T5, to be perfomed during the semester, online, using the Moodle platform. The calendar of these tests is available in the Moodle.
The final grade for the continuous evaluation (T) will be the average of the four best grades obtined in the five tests. This rule is also applied in case of not attending one of the tests. The grade for tests not attended is zero. In case of justified absence (request for justification must be submitted to the academic services) to more than one test, the student must contact one of the professores to have an alternative form of evaluation.
The final grade will be calculated using the following formula:
Final grade = 0,30 x T + 0,70 x E
in which E is the grade obtained in the exam. Students be approved if the final grade is equal or higher than 9.5 and the exam grade, E, is equal or higher than 8.0.
This formula will be used in the normal exam and in the appeal exam, for approval at the unit course.
Special assessment (TE, DA, ...)
Working students may opt for evaluation by the final exam only.
Classification improvement
The students that want to obtain a better final grade can repeat the global exam in the appeal exam. The grade will be the one obtained in the appeal exam, if higher than the grade obtained previously.
