Reaction: N2 + H2 → NH3
Balanced Reaction: N2 + 3 H2 → 2 NH3
Blue spheres represent N (2 blue spheres together = N2):
• 4 molecules N2
White ones represent H (2 white spheres together = H2):
• 9 molecules N2
Calculate how much NH3 can be produced by each reactant:
• From 4 molecules N2
NH3 molecules = 8 molecules
• From 9 molecules H2
Nitrogen (N2) and hydrogen (H2) react to form ammonia (NH3). Consider the mixture of N2 and H2 shown in the accompanying diagram. The blue spheres represent N, and the white ones represent H.
How many N2 molecules are left over?
