For 2-3 months it is impossible to learn (repeat, pull up) such a complex discipline as chemistry.
There are no changes in KIM USE 2020 in chemistry.
Don't delay your preparation.
- Before starting the analysis of tasks, first study theory. The theory on the site is presented for each task in the form of recommendations that you need to know when completing the task. guides in the study of the main topics and determines what knowledge and skills will be required when completing the USE tasks in chemistry. For successful passing the exam in chemistry, theory is the most important thing.
- Theory needs to be backed up practice constantly solving problems. Since most of the errors are due to the fact that I read the exercise incorrectly, I did not understand what is required in the task. The more often you solve thematic tests, the faster you will understand the structure of the exam. Training tasks developed on the basis of demos from FIPI give them the opportunity to decide and find out the answers. But do not rush to peek. First, decide for yourself and see how many points you have scored.
Points for each task in chemistry
- 1 point - for 1-6, 11-15, 19-21, 26-28 tasks.
- 2 points - 7-10, 16-18, 22-25, 30, 31.
- 3 points - 35.
- 4 points - 32, 34.
- 5 points - 33.
Total: 60 points.
The structure of the examination paper consists of two blocks:
- Questions that require a short answer (in the form of a number or word) - tasks 1-29.
- Tasks with detailed answers - tasks 30-35.
For execution examination work Chemistry is given 3.5 hours (210 minutes).
There will be three cheat sheets on the exam. And they need to be dealt with.
This is 70% of the information that will help you successfully pass the exam in chemistry. The remaining 30% is the ability to use the provided cheat sheets.
- If you want to get more than 90 points, you need to spend a lot of time on chemistry.
- To successfully pass the exam in chemistry, you need to decide a lot:, training tasks, even if they seem light and of the same type.
- Correctly distribute your strength and do not forget about the rest.
Dare, try and you will succeed!
The result of the Unified State Examination in Chemistry not lower than the minimum set number of points gives the right to enter universities for specialties where the list of entrance examinations includes the subject of chemistry.
Universities do not have the right to set a minimum threshold for chemistry below 36 points. Prestigious universities tend to set their minimum threshold much higher. Because in order to study there, first-year students must have very good knowledge.
On the official website of FIPI, versions of the Unified State Examination in Chemistry are published every year: demonstration, early period. It is these options that give an idea of the structure of the future exam and the level of complexity of tasks and are sources of reliable information in preparing for the exam.

IN USE options in chemistry in 2017 there are changes compared to the KIM of the last 2016, so it is advisable to train according to the current version, and for the diverse development of graduates, use the options from previous years.
Additional materials and equipment
For each version of the exam USE work In chemistry, the following materials are attached:
− periodic system chemical elements DI. Mendeleev;
− table of solubility of salts, acids and bases in water;
− electrochemical series of voltages of metals.
It is allowed to use a non-programmable calculator during the examination work. The list of additional devices and materials, the use of which is allowed for the Unified State Examination, is approved by the order of the Ministry of Education and Science of Russia.
For those who want to continue their education at a university, the choice of subjects should depend on the list of entrance tests in the chosen specialty
(direction of training).
The list of entrance examinations in universities for all specialties (training areas) is determined by the order of the Russian Ministry of Education and Science. Each university chooses from this list those or other subjects that are indicated in its admission rules. You need to familiarize yourself with this information on the websites of selected universities before applying for participation in the Unified State Examination with a list of selected subjects.
Typical test tasks in chemistry contain 10 options for sets of tasks, compiled taking into account all the features and requirements of the Unified State Exam in 2017. The purpose of the manual is to provide readers with information about the structure and content of KIM 2017 in chemistry, the degree of difficulty of tasks.
The collection contains answers to all test options and provides solutions to all tasks of one of the options. In addition, examples of forms used in the exam are given to record answers and decisions.
The author of the tasks is a leading scientist, teacher and methodologist, who is directly involved in the development of control measuring materials for the exam.
The manual is intended for teachers to prepare students for the exam in chemistry, as well as for high school students and graduates - for self-training and self-control.
Examples.
Ammonium chloride contains chemical bonds:
1) ionic
2) covalent polar
3) covalent non-polar
4) hydrogen
5) metal
From the proposed list of substances, select two substances, with each of which copper reacts.
1) zinc chloride (solution)
2) sodium sulfate (solution)
3) dilute nitric acid
4) concentrated sulfuric acid
5) aluminum oxide

IN KIMah USE In 2017, the following changes will be made:
1. The approach to structuring part 1 of the examination paper will be fundamentally changed. It is assumed that, unlike the examination model of previous years, the structure of part 1 of the work will include several thematic blocks, each of which will present tasks of both basic and elevated levels difficulties. Within each thematic block, tasks will be arranged in ascending order of the number of actions that are necessary to complete them. Thus, the structure of part 1 of the examination paper will be more consistent with the structure of the chemistry course itself. Such structuring of Part 1 of the KIM will help the examinees during their work to more effectively focus their attention on the use of what knowledge, concepts and patterns of chemistry and in what relationship will require the completion of tasks that test the assimilation educational material certain section of the chemistry course.
2. There will be noticeable changes in approaches to task design basic level difficulties. These can be tasks with a single context, with the choice of two correct answers out of five, three out of six, tasks “to establish a correspondence between the positions of two sets”, as well as calculation tasks.
3. Increasing the differentiating ability of tasks makes it objective to raise the question of reducing the total number of tasks in the examination paper. It is planned to reduce the total number of tasks in the examination paper from 40 to 34. This will be done mainly by streamlining the optimal number of those tasks, the implementation of which involved the use of similar activities. An example of such tasks, in particular, are tasks focused on checking chemical properties salts, acids, bases, conditions for ion exchange reactions.
4. A change in the format of tasks and their number will inevitably be associated with an adjustment in the grading scale for some tasks, which, in turn, will cause a change in the initial total score for the performance of the work as a whole, presumably in the range from 58 to 60 (instead of the previous 64 points).
The planned changes in the examination model as a whole should result in an increase in the objectivity of testing the formation of a number of subject and meta-subject skills, which are an important indicator of the success of mastering the subject. We are talking, in particular, about such skills as: apply knowledge in the system, combine knowledge about chemical processes with an understanding of the mathematical relationship between different physical quantities, independently evaluate the correctness of the implementation of the educational and educational-practical task, etc.
