About preparing students for the solution of computational problems in chemical formulas

Authors:

Bazhina I. A.. Adress: Kazan. Workplace: Kazan (Volga region) Federal University.

Sharafieva L. M.. Adress: Kazan. Workplace: Secondary school №69.

Volkova T. I.. Adress: Kazan. Workplace: Secondary school № 70.

Summary

When solving computational problems quantitative (mole, mass or volume) the relationship of the substances entering into the reaction and the resulting reaction should be considered. This information can be obtained by referring to chemical formulas. It can be used by pupils or students in solving all types of computational problems. This eliminates the need to "train" them to the solutions of the model calculations, which we believe to be ineffective formality.

Keywords:

Chemical formula, molar, mass and volume relations of the substances participating in the reaction and the resulting reaction.
