Final answer:
To identify the limiting reactant between O2 and C10H8, the balanced chemical equation is needed to compare the mole ratios of the reactants. Without the balanced equation, it is not possible to determine the limiting reactant.
Step-by-step explanation:
To determine the limiting reactant when 12 moles of O2 (oxygen) react with 1.1 moles of C10H8 (naphthalene), we need the balanced chemical equation for the reaction. However, without the balanced equation, we can't specify which reactant is limiting since we don't have the stoichiometric coefficients necessary to compare the mole ratios. Generally, to find the limiting reactant, divide the number of moles of each reactant by its stoichiometric coefficient in the balanced equation.
If you do provide the balanced equation for the reaction between O2 and C10H8, you will be able to identify the limiting reactant by determining which reactant has the smaller number of moles when divided by its coefficient, indicating that it will be completely consumed first in the reaction.
