Examples of complete chemical equations to balance. The first step in balancing a chemical equation is to identify your reactants and your products. Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents.
For this equation our reactants are Fe and O2.
D 6a 6. N2 H2 - NH3 On the left there is 2 N and 2 H On the right there is 1 N and 3 H. C 6a 61 6. Substituting the values of ac and d in the equation 6a 2b 2c d the value of b can be obtained as follows.
