The reaction between aluminum metal (Al) and oxygen gas (O2) will yield a product called aluminum oxide with the chemical formula, Al2O3. The reaction is shown below,

Al + O2 - - - > Al2O3

We need to multiply Al by 2 and O2 by 3/2. To eliminate the fraction, multiply both sides of the chemical reaction by 2. These operations give a final answer of,

4Al + 3O2 - - - > 2Al2O3
