Chemistry

Basic knowledge of chemistry.

Theoretical classes will be oriented towards understanding the basic notions of the curricular unit, being complemented with theoretical-practical classes for problem solving and case studies.

In theoretical and theoretical-practical classes, the subject will be exposed through the use of a PowerPoint slide projection system.

The main purpose of the curricular unity is to provide the student a global view of Chemistry, in order to consolidate and deepen the knowledge acquired previously. It is also intended to introduce the student to the field of Organic Chemistry, giving special emphasis to the structure, nomenclature and physicochemical characteristics of the main families of organic compounds. Thus, the student should be able to i) understand the basic concepts of chemistry, chemical bonds and mass relations in chemical reactions, state of matter, thermochemistry and chemical equilibrium; ii) identify reactions of precipitation, acid-base, oxidation-reduction and reactions with oxygen; iii) identify the functional groups of organic compounds and their properties; iv) determine the structure of an organic compound from its name and vice versa v) identify and classify different isomers of organic compounds

1. Basic concepts

Atom composition and structure. Classification and periodic properties. Chemical bond. Chemical reactions and equations. Stoichiometry.

2. States of matter: gases, liquids and solids

Characteristics and properties of the gaseous, liquid and solid state.

3. Chemical and physical changes in reactions: Energy, kinetics and equilibrium

Thermochemistry. Chemical reaction kinetics. Chemical equilibrium. Reaction energy.

4. Reactions and solutions

Types of reactions: precipitation, acid-base, oxidation-reduction and reactions with oxygen. Properties of aqueous and colloidal solutions. Gas solubility.

5. Origins and importance of Organic Chemistry

Electronic and molecular structure of organic compounds. Electronic displacement. Resonance hybrids. Physical and chemical properties.

6. Functional groups and nomenclature

Properties.

7. Stereochemistry

Constitutional isomers and stereoisomers

The access to the Normal exam season is restricted to the students who do not opt ​​for periodic assessment or who do not meet the requirements for this type of periodic assessment. For the recourse exam there are no restrictions to the exam access.

Assessment Methodology
Ordinary students and working-students, may choose one of the two Assessment Methodologies:

A) Periodic evaluation
This assessment methodology will consist of in 2 tests throughout the semester, quoted for 20 values. The Final Classification of the Course Unit will result from the application of the following equation: CFinal= 0.5×T1+0.5×T2, where T1 is the classification obtained in the 1st test, T2 the classification obtained in the 2nd test. Students who choose this method of assessment must obtain a minimum attendance of 70% in lessons until the date of each test. The realization of the 2nd test by the students is subject to a minimum classification of 7 values in the 1st test.
Students who initially opted for periódic assessment and do not meet the requirements mentioned above or who desist of the 2nd test, will be directed to the method of Assessment by exam.

B) Final exam
This assessment methodology will consist of a Global Exam in the Normal Season and will have a quotation of 100% . In order to approved the Chemistry Curricular Unit, students will have to obtain a Final Classification equal to or greater than 10 values (from 0 to 20).

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

Graphic calculators are not permitted. Students may only use simple scientific calculators that are non-alphanumeric and non-programmable (i.e., models that do not have the full alphabet visible on the keyboard and do not save text).

The use of supplementary oral examinations may constitute an additional assessment tool, whenever deemed necessary to resolve doubts or clarify situations suspected of fraud or plagiarism.
