Question

Can any one please help me to answers this question i don't get it. thank in advance.

What is the limiting reactant when 6.8 moles of iron react with 8.9 moles of oxygen gas?

Unbalanced equation: Fe + O2 → Fe2O3

Show, or explain, all of your work along with the final answer.

Answer 1

4Fe + 3 02 -> 2Fe2O3 (balanced equation)

\[6.8 mol Fe * (2 Mol Fe2O3/4molFe)= 3.4 molFe203\]

\[8.9mol O2 * (2 mol Fe2O3/3 mol O2)= 5.93mol Fe2O3\]

Because Iron produces less it is limiting reagent

Answer 2

hope that helps
