全国高中学生化学竞赛基本内容（Basic content of chemistry competition for senior high school students in China）The national high school student chemistry competition basic content.Txt, the real good friend is not together has the topic which cannot say, but is together, even if does not speak, will not feel embarrassed. When you look at other people, you are also the scenery in other people's eyes. The road to tomorrow must remember the road that we walked yesterday and the road we are walking today. Basic content of chemistry competition for senior high school students in China

The 1. national chemistry contest of senior high school students (preliminary division contest) and final (winter) two stages, plus the winter after the national team players qualifying in three stages. The basic contents of the preliminary and final examination reflects the national level, is the basis of the examination proposition. The selection of the national team's athletes shall be based on the preparation of the International Chemistry Olympiad in the year.

2. the current middle school chemistry teaching requirements and contents are preliminary examination shows that the content of the provisions. A consistent level of content knowledge in preliminary principle to full-time high school chemistry textbook published by people's education press, but for some of the chemical principle of the quantitative relationship, material structure, solid chemistry and organic chemistry and other supplements, in general, supplementary content is the natural growth point in chemical content. The preliminary requirements of knowledge in order to achieve international

chemical descriptive chemistry contest outline level as the standard, the outline of the two or three levels of knowledge are not required in the application of memory based on.

The basic content of the final 3. is properly based on the basic contents of preliminaries, descriptive chemistry knowledge principle to reach the international level two level of knowledge of chemistry contest syllabus for the degree, the outline of the three levels of knowledge are not required in the application of memory based on.

4., pay attention to the intersection and interpenetration of chemical knowledge and non chemical knowledge, but the requirements of mathematics and physics knowledge should not exceed the requirements of middle school syllabus.

5. basic content, if necessary, will be adjusted and announced in mid August 2001.

The basic content of the preliminaries

1. the concept and application of effective numbers. Correct use of effective figures in chemical and chemical experiments. Quantitative instrument (analytical balance, cylinder, pipettes, burettes, flask etc.) the effective number of precision and measuring data. The valid number of the result of the operation.

2. ideal gas standard condition. Ideal gas equation of state. Gas density. Determination of relative molecular mass of gases. Gas solubility. Law of partial pressure.
