Answer: 62 moles of \(O_2\)
Explanation:
Combustion is a type of chemical reaction in which a substance is reacted with oxygen to form carbon dioxide and water.
The balanced chemical reaction for combustion of \(C_6H_{14}\)
\(2C_6H_{14}+19O_2 \rightarrow 12CO_2+14H_2O\)
From the stoichiometry:
2 moles of hexane react with = 19 moles of oxygen
Thus 6.5 moles of hexane react with = \(\frac{19}{2}\times 6.5=62\) moles of oxygen
Thus 62 moles of \(O_2\) are required to react completely with 6.5 moles of \(C_6H_{14}\).
