Chemistry =>Chemical Reactions => Balancing equations

We have the oxidation of iron in the equation.

To balance the equation we must start by counting the atoms of each element on both sides of the reaction.

We will balance the oxygen. We have 2 atoms of oxygen on the reactants. So we write coefficient 2 on the FeO molecule.

[tex]Fe+O_2\rightarrow2FeO[/tex]

Now, we balance the iron. We have 2 Fe atoms, so we write the coefficient 2 on the Fe molecule. We have:

[tex]2Fe+O_2\rightarrow2FeO[/tex]

Now, the equation of the reaction is balanced.

Answer: 2Fe + O2 →2FeO
