fe0+O2=fe2o3
4FeO + O2 >> 2Fe2O3
A word of caution here. fe is NOT the same thing as Fe or FE. For example, CO is carbon monoxide. Co is cobalt. co (or co.) is an abbreviation for company.
The equation you provided, fe + O2 = Fe2O3, represents the reaction between iron (Fe) and oxygen (O2) to form iron(III) oxide (Fe2O3), also known as rust.
To balance the equation, we need to make sure that the same number of each type of atom appears on both sides of the equation.
Let's start by looking at the iron (Fe) atoms. There is only one Fe atom on the left side, so we need to have two Fe atoms on the right side to balance it.
Next, let's consider the oxygen (O2) atoms. There are two O atoms in Fe2O3 and three O atoms in O2. So, we need three O2 molecules on the left side to have a total of six O atoms.
Now, let's balance the equation:
2Fe + 3O2 → Fe2O3
Now, the equation is balanced because we have an equal number of Fe and O atoms on both sides. Two Fe atoms on the left side react with three molecules of O2 on the left side to form two molecules of Fe2O3 on the right side.
