Question

Q3. 2 moles of octane ( C8H18) burns with 25 moles of oxygen (O2) and produced moles of carbon dioxide along with 18 moles of water A) 14 C) 18 D) 2 B) 16​

Answer 1

Answer:

so 16 is the correct answer

Explanation:

From the balanced equation, 25 moles of O2 react with 2 moles of octane during a combustion to produce 16 moles of CO2 and 18 moles of water. Therefore, 7.375 mol of O2 react with (2/25) x 7.375 = 0.590 mol of octane during the combustion to produce the said products.
