And then all we need to do is balance the equation.

Following are different steps of writing a chemical equation: Identify the type of reactant and product.Write the chemical formula for each of the reactants and products.Count the number of each type of atom in reactants and products.Balance the equation.

To balance equations on your own, follow these simple rules: Check that all the formulae in the equation are correct. Deal with only one element at a time. Balancing is adding BIG numbers. You cannot change any of the small numbers in a chemical formula.Check each element again and repeat step 3 again if needed.

The first step in balancing a chemical equation is to identify your reactants and your products. Remember, your reactants are on the left side of your equation. The products are on the right side. For this equation, our reactants are Fe and O2.

In general, however, you should follow these steps: Count each type of atom in reactants and products.Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.Repeat steps 1 and 2 until the equation is balanced.

A reaction is "completed" when it has reached equilibrium that is, when concentrations of the reactants and products are no longer changing. If the equilibrium constant is quite large, then the answer reduces to a simpler form: the reaction is completed when the concentration of a reactant falls to zero.
