If you have 3.50 moles of hydrogen and 5.00 moles of nitrogen to produce ammonia, which element is the reactant in excess? 3h2 + n2 → 2nh3

nitrogen

Explanation:

The stoichiometry of the reaction says that and   react 3:1 to form 2 moles of  , so, if you have 3,5 moles of H, which is equal to 1,75 moles of  , and 5 moles of N, which are equal to 2,5 moles of  . only=0.583 moles of  , will react, leaving 1.917 moles of unreacted, and forming 0.583*2=1.166 moles of
