I developed a program for balancing chemical equations. A beta-version of this program already was available, but now I present a new version, which allows the use of preserved groups (useful for organic chemistry) and the use of isotopes.

 

The program can be used for balancing any chemical equation, e.g. it nicely balances equations like the following:

 

[ce]..K2Cr2O7 + ..KCl + ..H2SO4 -> ..KHSO4 + ..Cr2O2Cl + ..H2O[/ce]

 

The program determines the coefficients, needed to make it correct:

 

[ce]K2Cr2O7 + 4KCl + 6H2SO4 -> 6KHSO4 + 2Cr2O2Cl + 3H2O[/ce]

 

The program can also do computations from moles to grams and vice versa and it computes weight ratios, needed for certain reactions. It also detects when a chemical reaction is non-stoichiometric (a nice example is the reaction between copper and nitric acid, where both NO and NO2 are formed) and the solution cannot be determined unambiguously. The program also allows the use of ions in the equations, so it can be used nicely for balancing equations, in which dissolved ionic compounds are involved, e.g. ions like Cl(-), Cr2O7(2-), MnO4(-), etc.

 

If you download the program, please also read the tutorial, before asking questions to me about the program.

 

Any feedback on the program, functionality, user interface, algorithms, is welcome.

 

The program is available at this page:

It is very easy to use, no installation needed, just click the icon and start playing....

Wow thats great, im going to become so lazy with chemistry now.
