GDZ control and measuring materials (kim) in chemistry Grade 9 Strelnikova Vako

At the end of the 9th grade, students will face the first serious test - an examination. They are waiting for assignments in the GIA format, and in another two years - testing the USE standard. Help you achieve successful results GDZ in chemistry!
KIM in chemistry is a collection of questions and tasks that allow you to implement various forms of control:
- current;
- thematic;
- final.
The manual prepared by E.N. Strelnikov, has become an integral part of the didactic complexes of teachers working according to the textbook by O.S. Gabrielyan. In grade 9, in chemistry lessons, the characteristics and properties of elements, the features of their interaction, the nature of the formation of compounds, etc. are analyzed. The course covers topics that are difficult to understand and requires complete immersion in the subject.
KIMs in chemistry - to knowledge in a straight line!
Gradually going through the questions and tasks of all levels of complexity for each section of the textbook, the student will repeat the lesson material, learn to apply knowledge in practice, and receive basic preparation for exams. Using the solution book, students and their parents will have the opportunity to independently work on each topic and compare their achievements with the standard.
If the result turned out to be deplorable, additions to the tests will help. With them, the correctness of the formulation of reaction equations and the progress of solving problems will no longer cause doubts. GDZ online - a storehouse of knowledge! Discover this handy tool, and chemistry will turn from a difficult and mystical science into an adored subject and an accessible hobby!

Explanatory note
