Answer: The coefficient for the diatomic oxygen (O2) is 3.
Explanation:
To know the coefficient for the diatomic Oxygen, we need to balance the equation.
Fe + O2 ------->   Fe2O3
 LHS of the equation; Fe =  1    , O2 = 1
 RHS of the equation; Fe = 2 ,  O = 3
 ∴ Multiply 'Fe' on the LHS of the equation by 4 and O2 by 3
    Doing that will give the balance equation which is;
     4 Fe +  3 O2  -------->  2 Fe2O3
The coefficient for the diatomic oxygen (O2) as seen from the equation is 3.
