Objectives
Students should understand general chemistry and its application in the graphic processes as well as the variables of chemical processes.
Program
Theoretical component:
1 - 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.
2 - Chemical bonding: Octet rule. Covalent bonds, ionic and metal. Nomenclature of ionic compounds.
3 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.
4 - Ionic balance: acid-base systems Bronsted-Lowry and Ahrrenius. The auto-ionization of water. The concept of pH. PH measurement: indicators and meters. PH electrode sensor. The reference electrode. Operation of the combined electrode. Temperature effect on the pH measurement. Calibration of the pH meter.
6 - Organic Chemistry: Alkanes and Cycloalkanes. Nomenclature of saturated hydrocarbons. Nomenclature of cycloalkanes. Functional groups: Alcohols and ethers; Aldehydes and ketones; Carboxylic acids; Esters; The amines; Amides; polymers
Practical component:
Practical work # 1 - Lab work for the ambiance of students to chemistry laboratory, knowledge of commonly used material, the use of analytical balances and familiarization with the descriptive statistical data analysis.
Practical work # 2 - laboratory work for the implementation of the stoichiometry of knowledge in the preparation of solutions for weighing, dilution and from concentrated solutions.
Pratical work # 3 - Laboratory work to determine the pH of paper.
Evaluation Methodology
Continuous assessment including practical and theoretical components. A minimum mark of 10/20 is required in both components. Final mark is as follows: theoretical component (60%)and practical component (40%).
