Collection of Problems and Exercises in Chemistry for Secondary School

This collection contains problems and exercises on all topics studied in secondary educational institutions (schools, lyceums, gymnasiums, technical schools, etc.). Solving them is an important element of studying the chemistry course, as it allows for better assimilation and systematization of theoretical material.

The arrangement of the material in the problem book corresponds to the most traditional sequence of studying chemistry in secondary school. It includes tasks of various levels of difficulty. Predominantly, these are the simplest and moderately difficult problems, but there is also a small number of tasks of increased difficulty so that the student can objectively assess the level of their knowledge. Most of the calculation problems included in the collection are provided with answers, which are given at the end of the book.
