Quizplus · Accepted Answer

The balanced chemical equation for the combustion of decane is:
C10H22 + 13O2 → 10CO2 + 11H2O
From the equation, we can see that 1 mole of decane reacts with 13 moles of oxygen gas to form 11 moles of water. Therefore, when 1 mole of decane undergoes complete combustion, 11 moles of water are formed.
