How to proceed:
Please write the balanced equation into the boxes below (before and after the red arrow).
Use normal numbers in formula instead of subscripts (as in K2SO4).
Write each formula into separate (bigger) box and corresponding stoichiometric coefficients into smaller one before that.
You can refrain from writing number ones as stoichiometric coefficients (they are the default values anyways).
You can add (buttons Add reactant/product) or delete (buttons with small cross, except for the very first reactant/product box) substances to your equation as needed.
The program discerns between uppercase and lowercase, and also between different brackets
(so Na4[Fe(CN)6] is correct and NA4[FE(CN)6],
na4[fe(cn)6], Na4(Fe(CN)6) or similar are not). Please pay attention!
