Objectives

The course "Química I (1st year, 1st semester) is the first chemistry course in 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 stoichiometry, chemical bonding,  chemical thermodynamics: 1st law, physical and chemical equilibrium (in particular acid-base equilibrium, solubility equilibrium and redox chemistry),and chemical kinetics.

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

Evaluation Type

Distributed evaluation without final exam

Assessment Components

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 THREE tests, T1 and T2 during the semester, and the third test will take place during the normal examination period.

The theoretical grade, NT, is the arithmetic average of the scores obtained in the 3 tests. A test not performed corresponds to zero.

NT = (T1+T2+T3)/3

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.
