4.5 ECTS; 1º Ano, 1º Semestre, 30,0 T + 30,0 TP + 2,0 OT

Lecturer
- Manuel Alberto Nogueira Henriques Rosa

Prerequisites
Not applicable.

Objectives
Understand the evolution of the concepts of structure of matter and the foundations and mechanisms of chemical bonding, stoichiometry and chemistry of salts in Heritage and Conservation and Restoration.

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 five assessment moments, three in the form of a written test and two in the form of a laboratory activity report. Each evaluation moment is quoted in 4 values for a final evaluation that totals 20 values. The student approves when the sum of the quotations obtained at all moments of assessment is equal to or greater than 10 values. In continuous assessment a minimum grade of 4 is required, without which the student will be excluded from the exam periods.
The evaluation in the periods of Normal Examination and Appeal Examination consists of a written test quoted at 20 points.

Method of interaction
Theoretical classes where the theoretical fundamentals are taught and practical laboratory classes where will be carried out measurement of volumes, weighings, preparation of solutions and identification od anions.
