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). For all their differences, the tasks of this part are similar in that the answer to each of them is written briefly in the form of one digit or a sequence of digits (two or three). The sequence of numbers is written in the answer sheet without spaces and other additional characters.
Part 2, depending on the CMM model, contains 3 or 4 tasks of a high level of complexity, with a detailed answer. The difference between examination models 1 and 2 is in the content and approaches to the implementation of the last tasks of the examination options:
Exam Model 1 contains task 22, which involves performing a "thought experiment";
Exam model 2 contains tasks 22 and 23, which provide for the performance of laboratory work (a real chemical experiment).
Scale for converting points into grades:
"2"– from 0 to 8
"3"– from 9 to 17
"four"– from 18 to 26
"5"– from 27 to 34
The system for assessing the performance of individual tasks and the examination work as a whole
The correct performance of each of the tasks 1-15 is estimated at 1 point. The correct performance of each of the tasks 16-19 is estimated as a maximum of 2 points. Tasks 16 and 17 are considered completed correctly if two answers are correctly selected in each of them. For an incomplete answer - one of the two answers is correctly named or three answers are named, of which two are correct - 1 point is given. The rest of the answers are considered incorrect and are scored 0 points. Tasks 18 and 19 are considered completed correctly if three matches are correctly established. Partially correct is the answer in which two out of three matches are established; it is worth 1 point. The remaining options are considered incorrect answers and are scored 0 points.
Checking the tasks of part 2 (20–23) is carried out by the subject commission. The 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
The manual contains 10 variants of standard test items for the 2016 Main State Exam.
The purpose of the manual is to develop the practical skills of students in preparing for the exam in grade 9 in chemistry in 2016.
The collection contains answers to all test options and provides a detailed analysis of all tasks of one of the options.
The manual is intended for teachers and methodologists who use tests to prepare students for the Main State Exam 2016, it can also be used by students for self-study and self-control.

Changes in the demonstration versions of the OGE in chemistry
In 2015 in demo versions of the OGE in chemistry was the structure of options has been changed:
- The variant began to consist in two parts.
- Numbering assignments has become through throughout the variant without letter designations A, B, C.
- The form of recording the answer in tasks with a choice of answers has been changed: the answer has become necessary to write digit with the number of the correct answer(not circled).
Since 2014, demonstration versions of the OGE in chemistry presented two models. These models differ 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, methodological materials were developed by the Federal Institute of Pedagogical Measurements. The choice of the exam model is carried out by the educational authorities of the constituent entities of the Russian Federation.
AT demo versions of the OGE 2016-2019 in chemistry compared to 2015 demos there were no changes.
In 2020, only one model of the demonstration version of the OGE in chemistry, in which, compared to the previous year 2019, the following changes:
- increased the proportion of items with multiple choice answers (6, 7, 12, 14, 15);
- increased the proportion of tasks to establish a correspondence between the positions of two sets (10, 13, 16);
- task 1 added, providing for testing the ability to work with textual information;
- in part 2 included task 21, aimed at checking the understanding of the existence of a relationship between different classes of inorganic substances and the formation 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 reduced ionic equation;
- added mandatory practical part, which includes two tasks: 23 and 24:
- in task 23 from the proposed list, it was necessary to select two substances, the interaction with which reflects the chemical properties of the substance specified in the condition of the assignment, and draw up two reaction equations with them;
- in task 24 it was necessary to carry out two reactions corresponding to the compiled reaction equations.
OGE series. FIPI - the school was prepared by the developers of control measuring materials (KIM) of the main state exam. The collection contains:
24 thematic options for all sections of the OGE codifier in chemistry;
10 typical exam options compiled in accordance with the draft demo version of KIM OGE in chemistry 2015;
instructions for performing the examination work;
answers to all tasks;
evaluation criteria.
Thematic options provide an opportunity to systematically prepare students for the state final certification in the 9th grade in the form of the OGE, and the fulfillment of tasks of standard examination options - to objectively assess the level of their preparation for the exam.
Teachers can use thematic and standard examination options to organize the control of the results of mastering the educational programs of basic general education by schoolchildren and intensive preparation of students for the OGE.

When completing assignments, you can use a draft. Draft entries do not count towards the assessment of the work. When performing work, use the Periodic Table of Chemical Elements D.I. Mendeleev; table of solubility of salts, acids and bases in water; electrochemical series of voltages of metals. These accompanying materials are attached to the text of the work. Use a non-programmable calculator for calculations. The points you get for completed tasks are summed up. Try to complete as many tasks as possible and score the most points.

Polymers (from the Greek polymeros - consisting of many parts, diverse) - substances whose molecules (Macromolecules) consist of a large number of repeating units - monomers. The molecular weight of polymers reaches 106, and the geometric dimensions of the molecules can be so large that solutions of these substances properties approach colloidal systems. The atoms that make up the macromolecules are connected to each other by the forces of the main and (or) coordination valences.
