Tests, tasks and reactions in organic and inorganic chemistry with the analysis of the theory

The application contains tests and tasks in chemistry to improve knowledge and prepare for the OGE and EGE in chemistry and other exams.

The questions are structured in such a way as not only to check the level of preparation, but also to teach the new material. Help is available for each topic, with a detailed description of the theory and examples.

- Chemical elements and periodic table;

- Chemical substances;

- Calculations and reaction rates, oxidation and reduction;

- Solutions, mixtures, electrolytes;

- Classes of chemicals and their properties;

- Chemical reactions and qualitative analysis;

- Chemistry in everyday life and life;

- Organic chemistry (nomenclature and classes of substances, alkanes, alkenes, alkynes, aromatic hydrocarbons, oxygen-containing, etc.);

- Organic chemistry (reactions);

You can also run a general test on all topics.
