Objectives
To learn basic knowledge of Chemistry. To promote recognition of its importance in nature, technological development and quality of life in society. Students should be able to solve basic problems of Chemistry and perform simple laboratory tasks.

Program
1. Revisions of fundamental concepts of Chemistry.
1.1. Chemical elements and their organization: Mass and size of atoms; Energy of electrons in atoms; Periodic Table. 1.2. Properties and transformations of matter: Chemical bond; Gases and dispersions; Chemical transformations.

2. Chemical equilibrium.
Quantitative aspects of chemical reactions. Chemical equilibrium and extent of chemical reactions.

3. Reactions in aqueous systems.
Acid-base reactions. oxidation-reduction reactions. Solutions and equilibrium solubility.

4. Metals and metal alloys.
Structure and properties of metals. Degradation
of metals. Metals, environment and life.

5. Fuels and environment.
Fossil fuels: coal, crude oil and natural gas. From where does the energy of the fuels come.

6. Plastics, glass and new materials.
