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, Nonmetallic Elements 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

Eligibility for exams

The students must have no more absences than 1/4 of the total number of the theorethical-practical classes.

There is no exemption from practical classes.

Calculation formula of final grade

The continuous evaluation is the average of the grade obtained in FOUR tests: T1, T2 and T3 during the semester, and the fouth test will take place during the normal examination period.

The theoretical grade, NT, is the arithmetic average of the scores obtained in the four tests. A test not performed corresponds to zero.

NT = (T1 + T2 + T3+ T4) / 4

In appeal time exam the student will carry out a comprehensive examination (all matter) and the classification obtained is NT.

Special assessment (TE, DA, ...)

Working students may opt for a comprehensive examination.

IN THIS CASE THEY MUST INFORM THE TEACHING STAFF.

Classification improvement

The students that want to obtain a better final grade may take a global exam in the appeal time of exams.
