Ionic charges are not yet supported and will be ignored. Chemical Equation Balancer 2 It is important to note that the balancing of an equation is accomplished by placing numbers in front of the proper atoms or molecules and not as subscripts. In an equation, all chemical species appear as correct formula units. The addition (or change) of a subscript changes the meaning of the formula unit and of the equation. I. THE MEANING OF A CHEMICAL EQUATION - chymist.com Balancing an unbalanced equation is mostly a matter of making certain mass and charge are balanced on the reactants and products side of the reaction arrow.
