Hey,

Thanks for replying, you have been very helpful, however Java gave me this
error when I tried to run your modification:

Exception in thread "main" java.lang.ClassCastException:
org.openscience.cdk.Atom cannot be cast to java.lang.String
        at ReactionBalancer.removeZeroEntries(ReactionBalancer.java:430)
        at ReactionBalancer.makeDiffHashtable(ReactionBalancer.java:187)
        at ReactionBalancer.balance(ReactionBalancer.java:140)
        at Tester.main(Tester.java:81)

on line 430, and at 263 specifically... I tried casting them as Objects and
as Atoms, but then it only gave the answer "false" when I did it on known
equations.

thanks, I feel we are on the verge of solving this. :)
