WebLimiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. The limiting reagent row will be highlighted in pink. Examples of complete chemical equations to balance: Fe + Cl 2 = FeCl 3 KMnO 4 + HCl = KCl + MnCl 2 + H 2 O + Cl 2 WebCr+3 + Cl-1 = Cr+3 + Cl-12. To balance the unbalanced chloride molecule charges, we add 2 in front of the chloride on L.H.S. We get, Cr+3 + (2)Cl-1 = Cr+3 + Cl-12. Now, the equation is balanced with 2 Chloride’s (Cl) with total charge -2 and 3 Chromium’s with total charge +3 on both sides. This is how the redox equations are balanced.
