Reack

This program allow us to balance chemical equations by entering the 'raw' reaction or its components.

There is also available a window to select    typical compunds. Also we can import (not balanced) chemical equations from a litle data base sorted by types: acid-base, combustion, redox, and so on. The new reactions that we introduce    can be also saved in this data base.

Equation balancing may be manual,    by the user, or automatic,    by the application. Then, upon the balanced equation you can perform stoichiometric calculations by entering data of quantities in different possible unities: gram, mole, volume of solution, volume of gas at s.c. or any other P, V, T    conditions.... Results are shown in the same table of the data.

From here a 'problem' can be built that involves the balanced equation of the reaction, data of reagents or products and qüestions about the unknown quantities of the other compunds, an scheme of resolution with the factors of conversion and the final results.

This 'problem' is shown in a new window and can be saved by means the File - Save option of its menu. From this menu you can also recover and view files saved earlier. Also exists a module (via Tools menu) to perform calculations on concentration of solutions.

As a whole, it's an integrated environment for the equations of the chemical reactions and their involved stoichiometry.
