#4"Al"# #+# #3"O"_2rarr2"Al"_2"O"_3#

#"Al"# #+# #"O"_2rarr"Al"_2"O"_3#

This is the unbalanced equation described.

Achieve a common #6# oxygen atoms on either side of the equation.

#"Al"# #+# #3"O"_2rarr2"Al"_2"O"_3#

Now, since there are #1# and #4# aluminum atoms on each side respectively, change the coefficient on the reactants side to #4#.

Balanced form:

#4"Al"# #+# #3"O"_2rarr2"Al"_2"O"_3#
