Objectives

Global aims:

To give a global vision of fundamental chemistry in an interface framework with questions of quotidian life; To develop a scientific reasoning; To pass on fundamental knowledge on chemistry that will support the student education on Bioengineering; To stimulate a critical mind, aiming to avoid the primary acceptance of results; To apply the acquired knowledge on laboratory work; To promote the student auto-sufficiency, valuing the search and use of recently published data.

Specific aims:

To create capacities for: i) interpreting the properties of gases and liquids; ii) evaluating the kinetic of chemical changes iii) quantifying the heat involved in physical and chemical changes; iv) evaluating the possibility of occurrence of the physical and chemical changes; v) quantifying the composition of equilibrium systems; vi) previewing and understanding the answer of systems to changes in equilibrium conditions.

Learning outcomes and competences

The process of teaching and learning is focused on work (autonomous and tutored) student, especially in implementing homework (exercises) at the end of each chapter as well as in reporting prior to the preparation of laboratory classes.

Apply the knowledge acquired in laboratory work; foster self-reliance of students, enhancing research recently published data; acquire personal and professional skills enabling them to develop thinking by identifying, formulating and solving problems related to phase equilibrium, and chemical equilibrium chemical kinetics.

Teaching methods and learning activities

Presentations supported by audiovisual media, and illustrated with the solution of problems related with practical examples, included in tutorial handouts to be delivered to the students. Special attention will be given to the application of knowledge in quotidian life issues, with interfaces with Bioengineering. Students will be strongly stimulated to participate during the classes. Presences will be registered.

Eligibility for exams

Exam eligibility is obtained by not surpassing the maximum number of absences allowed and has a minimum grade of 10 (in 20) in lab classes.

Grading will be based on successful execution of the lab works/lab notebooks (20%), final report (40%) and a written test (40%).

Calculation formula of final grade

The final grade (CF) is calculated by the following formula:

CF = 0,75xCT + 0,25xCP

Where CT =0,50 CT1 + 0,50 CT2, being CT1 the grade of the 1st test and CT2 the grade of the 2nd one, and CP the practical component (lab classes).

Course is considered to be passes with a theoretical grade (CT) higher or equal to 10 and a minimum grade for the practical component (CP) values ≥ 10 and 8 points in the classification of tests / examination (CT / Exam).
