Summary

The current article is written about adjustment methods of redox reactions. The author states that the visibility and effectiveness of electronic balancing and half-reaction methods can be increased in the case if there in terms of general approach is a combination of both, electronic balancing and half-reaction methods, which is then called method of electronic half-reaction balance. To implement the proposal author suggests adjustment process equalizing amount of electron given and amount of electron received as well as process of transmission of half-reaction, which are reflected on the general picture of sequence.

Chemical experiment

The decision of the experimental tasks on the theme of «Metals»

Authors:

Shiryaeva M. Yu.. Adress: Mosсow. Workplace: School №1413.

Summary

A significant place in the content of the course chemistry is given chemical experiment. It opens up the possibility of forming students ' specialised skills to work with substances which teaches students the safe and proper handling of substances in class, at home and at production. The main role of practical work is the development of students ' scientific thinking, formation of skills of intellectual penetration into the essence of the studied phenomena, to encourage interest in science, in communion to the scientific research, etc. Practical work should be done with due account of the interests of the students, to have a practical focus to wear an element of entertainment. Statement of problem issues, modeling of problem situations, creative tasks should become a logical addition to the lesson. Such activity approach in teaching chemistry makes a successful practical work, increases the interest to the research activity of pupils and the subject in General.
