I have had a long look at both of those links, and I'm still just as confussed.
Can someone please help me when balancing equations like the one i gave in the example at the start?
You did realize that you could just cut and paste a chemical equation into the Javascript applet on the page I linked to, and get the answer, and a stepwise explanation, right?
'Course, it won't work with your example above, because you're missing a hydrogen in your example, that was mentioned in the body of text in your question. Even by hand, with the best explanation possible, you can't balance an incorrect equation.
1 mole of C4H4O4 is neutralised by 2 mol of KOH.
Complete and balance the equation below for this reaction.
reactant + reactant ----> product + product
....KOH + ....C4H3O4 ----> ....K2C4H2O4 + H2O
That could be why you can't figure it out.
