It may seem to some that chemistry is like magic - just as incomprehensible. But once you understand the subject, you will see logic and beauty in it.

8th grade
Let's get acquainted with the basic concepts in chemistry, the structure of atoms and molecules, chemical substances and reactions. Examples of topics:

The concept of a chemical element and the form of its existence

How an atom is structured and what is relative atomic mass

What are the intermolecular interactions and types of crystal lattices?

What are chemical bonds and under what conditions do they occur?

9th grade
Let's remember the basic concepts learned in 8th grade and deepen our knowledge of inorganic chemistry. Examples of topics:

Avogadro's law

Cations and anions

Mixtures and chemical contamination

Properties of acids, salts and bases 

Grade 10
In the 10th grade, it’s time to start preparing for the Unified State Exam. As part of this task, we will refresh our knowledge about organics and inorganics. Examples of topics:

Classification and nomenclature of organic substances

Types of bonds in organic molecules

Relationship between organic compounds

Determining the molecular formula of a substance 

Grade 11
Let's remember the basics of chemical sciences, refresh our knowledge about reactions, and review organic and inorganic chemistry. Examples of topics:

Thermal effect and volumetric ratios of gases

Chemical properties of esters

Properties of monohydric and polyhydric alcohols

Problems to find the molecular formula of an organic compound
