Consider the Reaction N₂(g)+ 2O₂(g)→ 2NO₂(g)

Consider the reaction N₂(g) + 2O₂(g) → 2NO₂(g) . The molecular image represents a mixture of N₂(g) and O₂(g) just before reaction occurs. What is the limiting reactant, and how much of the excess reactant remains after the reaction is complete? The image contains 3 N₂ molecules and 9 O₂ molecules.

A) N₂(g) , 6 O₂(g)
B) O₂(g) , 1 N₂(g)
C) N₂(g) , 3 O₂(g)
D) O₂(g) , 2 N₂(g)
E) N₂(g) , 7 O₂(g)
