The writing of this book was done in such a way that the student starts from the theory and effectively understands complex chemical concepts, learns the methodology for solving exercises from the solved applications, and continues with solving exercises and problems of increasing difficulty. In this way, they gain a deep understanding of the material for the 2nd year of high school, become familiar with the logic of exam topics, and acquire strong foundations that will help them in studying Chemistry for the 3rd year of high school.

Each chapter consists of sections, each of which follows the following structure:

- Presentation of theory in the form of questions and answers. This way, the student can focus on the most important points of each lesson and quickly review whenever deemed necessary.
- Solved applications, which present the methodology for solving almost every type of exercise, in the form of steps.
- Evaluation questions, which are categorized as follows:
-short answer
-fill in the blanks
-matching
-multiple choice
-true/false
- Exercises and combined problems that cover, in multiple ways, the material of the sections and expand the field of applications.
- Evaluation criteria, so that the student can self-assess and adjust their personal study.

Answers to all evaluation questions and solutions to all exercises & criteria.
