Final answer:
To calculate how many moles of butane are needed to produce 5 moles of water, the balanced equation of butane's combustion is necessary. By examining the stoichiometry, half the amount of butane to water produced in the reaction is needed. Without the actual equation, we cannot provide an accurate answer.
Step-by-step explanation:
To determine how many moles of butane gas, C4H10, react to produce 5.00 mol of water, we would need the balanced chemical equation for the combustion of butane:
2 C4H10 + 13 O2 → 8 CO2 + 10 H2O
From the stoichiometry of the balanced equation, we see that 2 moles of butane produce 10 moles of water. Therefore, to produce 5 moles of water, we will need half the amount of butane, which is 1 mole. The answer is:
- A. 2.5 moles of butane gas.
However, since the actual balanced equation of the combustion of butane is not provided, we cannot choose an accurate answer from the given options without assumptions. Thus, it is generally essential to clarify or include the correct equation for a precise answer.
