basic knowledge of chemistry

The theoretical contents are presented in theoretical lessons, and then these contents are applied to practical exercises carried out in theoretical-practical lessons. In PL lessons, students perform laboratory experiments to consolidate the knowledge transmitted in T and TP lessons, as well as to increase their understanding of the scientific method, namely observation, recording, critical thinking and writing of scientific reports.

The objectives defined for the UC of Chemistry are related to its fundamental role, generalist and pedagogical support to the study of Engineering. It is intended to provide to the students the fundaments bases of chemistry that underlie the transformation and characterization of matter and the structures that it forms. The skills to be acquired by the student are: Solve physical-chemical problems, using an appropriate form. Identify, interpret and know how to communicate the relationship between microstructure and material properties. Interpreting and equating physico-chemical problems involving homogeneous or heterogeneous systems. Predict the direction of evolution the chemical systems based on thermodynamic data. Interpret and communicate mechanisms by electrochemical processes. Complement and consolidate knowledge of the subjects covered in the course through laboratory practice, being able to access new knowledge by the use of the bibliographic material.

The access to the exam seasons, the student must obtain (or have obtained in the previous three academic years) a minimum attendance of 75% in practical classes for to be admitted to the assessment.

Assessment Methodology

The assessment will consist of a Global Exam (TA) during the respective exam season and will have a score of 75%. The remaining 25% corresponds to the grade obtained in the practical laboratory component previously obtained throughout the semester by continuous assessment (PA).

The grade for the practical component completed in the previous three years remains valid, if positive, for the current academic year.

The final grade for this curricular unit is calculated by the formula: 0.75 x TA + 0.25 x PA.

To get approval the General Chemistry, students must obtain a final grade equal or higher than 10 (from 0 to 20).

In assessment methodologies, the use of elements provided by the teacher on the assessment day is only allowed. The use of a calculating machine is allowed.
