MULTIPLE CHOICE QUESTION

What is the limiting reactant if 15 GRAMS of NH3 react with 16 GRAMS of NO?
4NH3+6NO --> 5N2 + 6H2O
(Remember, convert grams to moles, then divide each substance by the number of moles given as the coefficient from the balanced chemical equation).

NHis the limiting because the reaction only requires 0.22 mol of NH3

NO is the limiting reactant because the reaction only requires 0.088 mol NO 

NHis the limiting because the reaction only requires 0.88 mol of NH3

NO is the limiting reactant because the reaction only requires 0.53 mol NO
