What is the limiting reactant when 5.6 moles of aluminum react with 6.2 moles of water? unbalanced equation: al + h2o → al2o3 + h2 show, or explain, all of your work along with the final answer.

The ratio of Al2O3 and Al is 1 to 2
5.6 mol of Al x (1 mol of Al2O3/2 mol of Al)
which is 2.8 mol of Al2O3.then the ratio of Al2O3 and H2O is 1 to 3 
6.2 mol of H2O x (1 mol of Al2O3/3 mol of H2O) which is 2.067 mol of Al2O3.hope this helps.Zane
