Question69. Consider the unbalanced equation for the combustion of hexane: $$\mathrm{C}_{6} \mathrm{H}_{14}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \longrightarrow \mathrm{CO}_{2}(\mathrm{~g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{~g})$$
Balance the equation and determine how many moles of $\mathrm{O}_{2}$ are required to react completely with $7.2 \mathrm{~mol} \mathrm{C}_{6} \mathrm{H}_{14}$.
