Problem Details
Consider the reaction:
2 CH3OH(g) + 3 O2(g) → 2 CO2(g) + 4 H2O(g)
Each of the molecular diagrams represents an initial mixture of the reactants.

Three space-filling molecular diagrams labeled a, b, and c. Diagram a is a collection of three molecules composed of a black and red sphere combined surrounded by four smaller white spheres (one on the red sphere and three on the black sphere), and three molecules composed of two red spheres combined. Diagram b is a collection of one molecule composed of a black and red sphere combined surrounded by four smaller white spheres (one on the red sphere and three on the black sphere), and six molecules composed of two red spheres combined. Diagram c is a collection of four molecules composed of a black and red sphere combined surrounded by four smaller white spheres (one on the red sphere and three on the black sphere), and two molecules composed of two red spheres combined.
