The course for bachelor students of chemistry, biology and geology.

The course is aimed at repeating and consolidation of basic knowledge of students that constitute the base for the individual work in chemikal laboratories. The students will solve the balance problems in compounds, mixtures and solutions and carry out the chemical calculations on the base of chemical equations.
