Answer:
$4Fe+3O_2\rightarrow 2Fe_2O_3$

Step-by-step explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation is:

$4Fe+3O_2\rightarrow 2Fe_2O_3$

Thus in the reactants, there are 4 atoms of iron and 6 atoms of oxygen.Thus there will be 4 atoms of iron, and 6 atoms of oxygen in the product as well.
