The combustion of butane (C₄H₁₀)forms carbon dioxide and water.What is the stoichiometric coefficient for oxygen in the balanced equation when 1 mol of butane undergoes combustion?

Question

Quizplus · Accepted Answer

The balanced chemical equation for the combustion of butane is:

2C4H10 + 13O2 → 8CO2 + 10H2O

From this equation, we can see that 13 moles of oxygen are required to completely combust 2 moles of butane. Therefore, the stoichiometric coefficient for oxygen when 1 mole of butane undergoes combustion is:

13/2 = 6.5

However, stoichiometric coefficients must be integers, so we round up to the nearest whole number, which is 7.

Therefore, the answer is C) 11.
