For the reaction shown, find the limiting reactant for each of the following initial amounts of reactants. 4Al(s)+3O2(g)→2Al2O3(s)
16 mol Al, 13 mol O2
11.4 mol Al, 9.5 mol O2
4 mol Al, 2.6 mol O2
1 mol Al, 1 mol O2
Can you please explain how to figure this out?
4Al(s)+3O2(g)→2Al2O3(s)
from balanced equation
3 moles of O2 react with 4 moles of Al
13 moles of O2 react with = 4*13/3 = 17.34 moles of Al is required.
Al is limitinf reactant
2.
from balanced equation
3 moles of O2 react with 4 moles of Al
9.5 moles of O2 react with = 4*9.5/3 = 12.67 moles of Al is required.
Al is limiting reactant
3
from balanced equation
4 moles of Al react with 3 moles of O2
4 moles of Al react with 3 moles of O2 is required
O2 is limitinf reactant
4.
3 moles of O2 react with 4 moles of Al
1 moles of O2 react with = 4*1/3 = 1.33 moles of Al is required.
Al is limiting reactant
