In an experiment, 3.0 g of sodium react with 1.0 g of oxygen, forming 4.0 g of sodium oxide. Determine the empirical formula for sodium oxide. Write a balanced chemical equation for this reaction. PLEASE, give a lot of detail for the balanced chemical equation part. I think it should be Na2 + O -> Na2O, but it keeps saying that is wrong.
