Identifying the Limiting Reactant in a Drawing of a Mixture

The problem presents a drawing of a mixture of molecules with the following key:

• Carbon
• Hydrogen
• Nitrogen
• Sulfur
• Oxygen
• Chlorine

The chemical reaction that can take place in this mixture is:

$4 NH<em>3(g) + 5 O</em>2(g) \rightarrow 4 NO(g) + 6 H_2O(g)$

The questions to answer are:

1. Of which reactant are there the most initial moles? Enter its chemical formula.
2. Of which reactant are there the least initial moles? Enter its chemical formula.
3. Which reactant is the limiting reactant? Enter its chemical formula.
