Course abstract

The course “Chemistry” students learn basic principles of inorganic and organic chemistry. The main topics of lectures are chemical elements, atomic structure, classification and nomenclature of inorganic and organic compounds, chemical properties of chemical compounds. During the laboratory works students learn preparation of solutions, signs of chemical reactions, qualitative analysis of organic compounds.

Requirements for awarding credit points

The written examination.
Every test, written during the semester, must have a positive mark ( at least 4). All home assignments and laboratory work protocols must have positive evaluation.

Description of the organization and tasks of students’ independent work

Home assignment No. 1. Student receive the task from the academic staff. The task “Fats and oils” is individually made for the student. The student is required to give written answers to some theoretical questions and write chemical reaction equations (electronic submission).
Home assignment No. 2. Student receive the task from the academic staff. The task “Monosaccharides and disaccharides” is individually made for the student. The student is required to give written answers to some theoretical questions and write chemical reaction equations (electronic submission).

Criteria for Evaluating Learning Outcomes

The final grade of the study course is obtained as the combination of all tests marks and examination mark.
The mark is calculated using a marking scheme:
• tests 30% ;
• examination 70% .
