Chemistry

The objectives defined for the Curricular Unit of Chemistry relate to its fundamental, generalist and pedagogical support role. The approach and development is based on the students’ specific level of knowledge, in view of their applicability to the study of chemical applications. It is intended to provide students with an understanding of the fundamentals of chemistry that it is underlie the transformation and characterization of the matter and the structures that it forms.
With this curricular unit it is intended that the students develop the skills, attitudes, behaviours, methodologies and the best practices, scientific reasoning and that they be able to:
?understand the basic concepts of chemistry, chemical bonds and mass relationships in chemical reactions, state of matter, chemical and thermochemistry equilibrium;
? identify the precipitation, complex formation, acid-base and redox reactions and understand the mechanism underlying to the respective titrations.

1.   Basic concepts. Electronic configuration of atoms and ions. Periodic table. Quantic numbers and atomic orbitals.
2.   Chemical bonds and nomenclature. Ionic bond. Lewis structures.
3.   Mass relationships in chemical reactions. Atomic masses. Avogadro number and molecular weight. Percent composition of the compounds and mixtures. Chemical reactions and chemical equations. Stoichiometry.
4.   States of matter: gases, liquids and solids. Characteristics and properties of gaseous state, liquid state, solid state.
5.   Reactions in aqueous solution. Solution, solute and solvent definitions. Electrolytic properties. Composition of solutions. Precipitation and complexation reactions and their titrations. Acid-base reactions and acid-base titrations. Oxidation-reduction reactions and oxidation-reduction titrations.
6.   Chemical and physical changes of the reactions: energy, kinetic and equilibrium. Thermochemistry. Kinetics of chemical reaction. Chemical equilibrium.
