Explanation:
Methylene is an organic compound
Answer is: four iron atoms <span>are reacting with every three molecules of oxygen.
Balanced chemical reaction: 4Fe + 3O</span>₂ → 2Fe₂O₃.
From chemical reaction: n(Fe) : n(O₂) = 4 : 3.
Ratios of atoms of iron and molecules of oxygen is 4 : 3..
There is four atoms of iron and six atoms of oxygen on both side of reaction.
