Question

Can somebody please answer this for me

4NH3+6NO --> 5N2 + 6H20

When a student runs this reaction in their chemistry lab, they notice that they run out SO quickly and some NH3 is left in the container. Which reactant is the limiting reactant?

N2

NH3

NO

water

Answer 1

NO

Step-by-step explanation:

• 4 NH₃ + 6 NO → 5N₂ + 6H₂O

Water and N₂ cannot be the answer because they are products of the reaction, not reactants.

The fact that some ammonia (NH₃) is left in the container once the reaction is finished tells us that NH₃ is the reactant in excess.

The remaining reactant is thus the limiting reactant. The correct answer is NO.
