Balancing equations: coefficients from conservation

Pick the balanced equation — then watch every element tally to equal counts on both sides. ChemKernel balances each reaction as the one integer solution of the conservation matrix, so the answer is derived, not guessed. Wrong options are named mistakes: a coefficient that leaves an element unbalanced, or the classic trap of changing a subscript (which silently swaps in a different substance). Coefficients balance the equation; subscripts define the compound and never change.
