FREE Expert Solution

We’re being asked to determine the coefficient of Al2O3 when the given chemical equation is balanced.


Recall that when balancing chemical equations, we have to make sure that the number of elements on both sides is equal with the lowest whole number coefficients.


Fe2O3(s) + Al(s) → Al2O3(s) + Fe(l)

Fe      2

O       3

Al      1

Fe     1

O       3

Al      2
