In the reaction represented by the equation #2Al_2O_3 -> 4Al + 3O_2#, what is the mole ratio of aluminum to oxygen?

1 Answer

#4:3#

Explanation:

As per the equation , #2# moles of Aluminum Oxide (#Al_2O_3#) produces #4# moles of Aluminum (#Al#) and #3# moles of Oxygen (#O_2#).

The ratio of #Al# to #O# is #(4 " moles")/(3 " moles")# = #4/3#
