Question

What is the limiting reactant when 5.6 moles of aluminum react with 6.2 moles of water? (4 points)

Unbalanced equation: Al + H2O → Al2O3 + H2

I balanced the equation just need help solving

Answer 1

Answer 2

2Al + 3H2O → Al2O3 + 3H2

Ratios of moles available to coefficient of reactant:

Al: 5.6/2 = 2.8

H2O: 6.2/3 = 2.1

H2O has a lower ratio of moles to coefficient so it is the limiting reactant.
