Interpretation :
Correct statement regarding the balanced equation for the combustion of ethane must be chosen from the given list.
Concept Introduction :
2 moles ethane reacts with 7 moles of oxygen to produce 6 moles of water and 4 moles of carbon dioxide.

Answer to Problem 63A
Correct answer: Option C is correct.
Explanation of Solution
Reason for correct option: Option C is correct because 2 moles ethane needs 7 moles of oxygen. So if higher mass of ethane is taken then oxygen will be limiting reagent as it will be consumed completely.
Reasons for incorrect options: Option A is incorrect as oxygen will be limiting reagent if equal mass of ethane and oxygen is taken.
Option B is incorrect as oxygen is the limiting reagent if equal moles of ethane and oxygen are taken.
Option D is incorrect as oxygen might be the limiting reagent even if higher mass of oxygen is taken.
