Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. states that matter cannot be created or destroyed. You cannot ADD or CHANGE subscripts! Also oxygen in its original state is O2 so there when first put equation together it reads - Ca + O2 --> CaO but you then need to balance the equation to ensure there is the same number of moles of each element on each side of the equation therefore giving 2Ca + O2 --> 2CaO. If the word equation is incomplete, complete it and write the balanced chemical equation. In all instances a skeleton chemical equation was given to us containing correct symbols and formulas for the reactants and products. This balancer can also help you check whether the equation is balanced or not, thus you may edit the equation and check it's balance. It made 4.0 grams of magnesium oxide (MgO).
