Balancing chemical equations.
| Download Stoichiometry desktop application (Windows 64bit) | Download Stoichiometry source code (Lazarus/Free Pascal) |
Description: Chemistry trainer application: Generation of stoichiometry exercises, displaying chemical
equations that the user must try to correctly balance. The chemical reactions are taken from a text file, actually containing 180
equation samples. For each of the reactants and products, the user has to enter the correct coefficient. Correct/false answers and
success percentage are updated after each user answer
Programming notes: The equations contained in the sample file are not balanced. The application does this
by itself. The routines used are the same as those used by my chemeq command line program. Have a look
at the description of that program for information about how the balancing is implemented.
Improvements: An algorithm other than my brute force approach to balance the equations.
Free Pascal features: Usage of subscripts in Free Pascal. Recursion (classic Pascal). Complex Pascal data
structures; string extraction; reading text files (classic Pascal)..
