Objectives
Development of capacities for the understanding of the themes of general chemistry and its application to the processes of conservation and restoration of works of art. Particularly in laboratory work to prepare solutions, measure and identification of salt anions.
Program
Theoretical component:
Structure of matter: properties of matter; extensive and intensive properties; density and temperature (scales). Classification of matter: mixtures and pure substances. The atoms. The discovery of subatomic particles. Atomic number and isotopes. Ions. Periodic table. Periodic variation of metals, non-metals and metaloids. Electronic configurations and the periodic table: variation of atomic properties.
Chemical bonding: Octet rule. Covalent bonds, ionic and metal. Nomenclature of ionic compounds.
Stoichiometry: atomic mass, mole, molar mass and chemical reactions. Hit chemical equations; solutions and molarity. Preparation of solutions for weighing, diluting and from concentrated solutions.
Salts: What are salts?; Soluble salts and insoluble salts; Hygroscopy and deliquescence; Importance of the salts in the patrimony; Movement of salts on the walls of a building; Identification of carbonates, chlorides and sulfates by chemical tests.
Evaluation Methodology
Continuous assessment consists of three written tests (T1, T2 and T3) and two reports of practical laboratory work (P1 and P2), all graded from 0 to 20 values. The final grade results from the average of the five assessments and must be equal to or greater than 10 values for approval.
Final continuous assessment grade=(T1+T2+T3+P1+P2)/5
The presence in practical laboratory classes is mandatory, as well as the group writing of reports of the practical work performed.
In the Exam, Appeal Exam, Worker-Student Exam and Special Exam periods, students will be evaluated in a theoretical test (T) classified from 0 to 20 values, with the final grade resulting from the following weighting with the average grade obtained in the reports of the two practical assignments (P):
Final grade exams=T*0.6+P*0.4
Students approval is obtained when the exam final grade is equal to or greater than 10 values.
