###### FREE Expert Solution

We are asked to find the limiting reactant for each of the following initial amounts of reactants: 4 Al(s) + 3 O2(g) → 2 Al2O3(s)
a. 1 mol Al, 1 mol O2
b. 4 mol Al, 2.6 mol O2
c. 16 mol Al, 13 mol O2
d. 7.4 mol Al, 6.5 mol O2

The ratio of Al(s) to O2(g) is 1.33.

• If the ratio is < 1.33→ Al(s) is limiting
• If the ratio is > 1.33 → O2(g) is limiting
