Question

Consider the reaction 4FeS2 + 11O2 → 2Fe2O3 + 8SO2. If 8 moles of FeS2 react with 15 moles of O2, what is the limiting reactant? (3 points)

SO2

O2

Fe2O3

FeS2

Answer 1

O2

Step-by-step explanation:

for find the limiting reactant you must calculate the moles of the reactants from the amount that you have and from the MM:

MM FeS2 = 120n = 26.2g / 120g/mol = 0,218 mol

MM O2 = 32n = 5,44g/32g/mol = 0,17 mol

The limiting reactant is

O2
