Answer:
[tex]4Fe+3O_2\rightarrow 2Fe_2O_3[/tex]
Explanation:
The unbalanced reaction of the reaction between iron and oxygen is shown below as:-
[tex]Fe+O_2\rightarrow Fe_2O_3[/tex]
On the left hand side,
There is 1 iron atom and 2 oxygen atoms
On the right hand side,
There are 2 iron atoms and 3 oxygen atoms
Thus,
Right side, [tex]Fe_2O_3[/tex] is multiplied by 2.
Left side, [tex]O_2[/tex] must be multiplied by 3 and [tex]Fe[/tex] by 4 so to balance iron and oxygen.
Thus, the balanced reaction is:-
[tex]4Fe+3O_2\rightarrow 2Fe_2O_3[/tex]
