Test

Subject: semi-annual Chemistry test work for grade 9

Purpose: An objective assessment of the level of mastering educational achievements of students in accordance with state-owned compliant standards for chemistry in the first half

Plan and structure of test tasks:

As a meter of knowledge and skills of students in chemistry, test tasks are used in the first half of the year. The work consists of 25 tasks. They are located at the increase in difficulties and are divided into 2 blocks.

BlockBUTcontains 20 tasks to each of which answers are given. When performing these tasks, select the correct answers from the proposed options.
