In the above diagram, the paired open spheres represent `H_(2)` molecules and the paired solid spheres represent `N_(2)` molecules. When the molecules in the box react to form the maximum possible amount of ammonia `(NH_(3)` molecules, what is the limiting reactant and how many molecules of `NH_(3)` can be formed?
A. `N_(2)` is limiting. 5 molecules of `NH_(3)` can be formed.
B. `N_(2)` is limiting. 10 molecules of `NH_(3)` can be formed.
C. `H_(2)` is limiting. 8 molecules of `NH_(3)` can be formed.
D. `H_(2)` is limiting, 12 molecules of `NH_(3)` can be formed.
