When the following reaction is properly balanced, the number of moles of O2 will be _____? C6H14 + O2 → CO2 + H2O

38 miles

19 moles

13 moles

None of these

Balanced Equation: $2 C_{6} H_{14} + 19 O_{2} \to 12 C O_{2} + 14 H_{2} O$

The coefficient of O₂ is 19, meaning 19 moles of O₂ are required.
