The collection contains 30 practice versions of exam papers in chemistry and is intended for preparation for the main state exam in 9th grade. The 31st option is the control one.
Each option includes test tasks different types and level of difficulty corresponding to parts 1 and 2 of the examination paper. At the end of the book, self-test answers to all tasks are given.
The proposed training options will help the teacher organize preparation for the final certification, and students will independently test their knowledge and readiness to take the final exam.

Examples.
The following statements are typical for methane
1) the molecule contains two carbon atoms
2) addition reactions are typical
3) does not dissolve in water
4) decolorizes bromine water
5) enters into substitution reactions with chlorine

For chemical elements of the VIA group of the periodic system with increasing relative atomic mass:
1) metallic properties are enhanced and valence in hydrogen compounds increases
2) the charge of the atomic nucleus and the radius of the atom increase
3) the number of electronic layers in the atom and the highest valence increase
4) non-metallic properties are enhanced and the number of electronic layers in the atom increases

Compounds with covalent polar and covalent nonpolar bonds are, respectively:
1) chlorine and hydrogen chloride
2) water and nitrogen

Part 1 contains 19 tasks with a short answer, including 15 tasks of a basic level of complexity (the serial numbers of these tasks: 1, 2, 3, 4, ...15) and 4 tasks of an increased level of complexity (the serial numbers of these tasks: 16, 17, 18, 19). Despite all their differences, the tasks in this part are similar in that the answer to each of them is written briefly in the form of one number or a sequence of numbers (two or three). The sequence of numbers is written on the answer form without spaces or other additional characters.

Part 2, depending on the CMM model, contains 3 or 4 tasks high level complexity, with a detailed answer. The difference between exam models 1 and 2 lies in the content and approaches to completing the last tasks of the exam options:

Examination model 1 contains task 22, which involves performing a “thought experiment”;

Examination model 2 contains tasks 22 and 23, which involve completing laboratory work(real chemical experiment).

Scale for converting points to grades:

"2"– from 0 to 8

"3"– from 9 to 17

"4"– from 18 to 26

"5"– from 27 to 34

System for assessing the performance of individual tasks and the examination work as a whole

Correct completion of each of tasks 1–15 is scored 1 point. Correct completion of each of tasks 16–19 is assessed with a maximum of 2 points. Tasks 16 and 17 are considered completed correctly if two answer options are correctly selected in each of them. For an incomplete answer - one of two answers is correctly named or three answers are named, two of which are correct - 1 point is given. The remaining answer options are considered incorrect and are scored 0 points. Tasks 18 and 19 are considered completed correctly if three correspondences are correctly established. An answer in which two out of three matches are established is considered partially correct; it is worth 1 point. The remaining options are considered an incorrect answer and are scored 0 points.

The tasks of Part 2 (20–23) are checked by a subject commission. Maximum score for a correctly completed task: for tasks 20 and 21 - 3 points each; in model 1 for task 22 – 5 points; in model 2 for task 22 - 4 points, for task 23 - 5 points.

To complete the examination work in accordance with model 1, 120 minutes are allotted; according to model 2 – 140 minutes

Basic general education ends with the Main State Exam of graduates, during which the compliance of their knowledge with the requirements of the state educational standard is checked.
The examination of 9th grade graduates of general education organizations is carried out in the form of testing.
Requirements for the level of training of graduates in chemistry specified in the federal component state standard general education, are the basis for the development of control measurement materials for the OGE.
According to these requirements, a certain system of knowledge about inorganic and organic matter, their composition, properties and application. This system of knowledge, which is based on the Periodic Law and the Periodic Table of Chemical Elements by D.I. Mendeleev, forms the invariant core of all general education programs in chemistry. In the proposed examination paper, it was this content that was the basis for the development of control measurement materials.
Target this manual is to acquaint teachers and students with the structure and content of the examination paper, to give the graduate the opportunity to independently check their readiness for new form chemistry exam - in the form of testing.

Changes in demo versions of the OGE in chemistry

In 2015 in demo versions of the OGE in chemistry was the structure of the options has been changed:

• The option began to consist two-piece.
• Numbering tasks became through throughout the option without letter designations A, B, C.
• The form for recording the answer in tasks with a choice of answers has been changed: the answer now needs to be written down number with the number of the correct answer(not circled).

Since 2014, demonstration versions of the OGE in chemistry presented two models. These models vary only in the practice-oriented tasks of the last part, Moreover, model 1 is similar to the work of previous years, and model 2 provides for the implementation real chemical experiment (tasks C3, C4 in the 2014 version and tasks 22,23 in the 2015-2016 versions). To organize and conduct a real chemical experiment in model 2, the Federal Institute of Pedagogical Measurements developed methodological materials. The choice of the exam model is carried out by the educational authorities of the constituent entities of the Russian Federation.

IN demo versions of the OGE 2016-2019 in chemistry compared to 2015 demo variants there were no changes.

In 2020 it was introduced only one model of the demonstration version of the OGE in chemistry, in which, in relation to the previous year 2019, the following occurred changes:

• increased proportion of tasks with multiple choice answers (6, 7, 12, 14, 15);
• increased the proportion of tasks to establish correspondence between the positions of two sets (10, 13, 16);
• added task 1, providing for testing the ability to work with text information;
• V part 2 included task 21, aimed at testing the understanding of the existence of a relationship between various classes of inorganic substances and the development of the ability to compose reaction equations that reflect this relationship. Another controlled skill is the ability to write equations for ion exchange reactions, in particular the abbreviated ion equation;
• added mandatory practical part, which includes two tasks: 23 and 24:
  • V task 23 from the proposed list it was necessary to select two substances, the interaction with which reflects Chemical properties the substance specified in the task condition, and create two reaction equations with them;
  • V task 24 it was necessary to carry out two reactions corresponding to the compiled reaction equations.
