A 20 mL mixture of ethane, ethylene, and...

A 20 mL mixture of ethane, ethylene, and `CO_2` is heated with `O_2`. After explosion, there was a contraction of 28 mL and after treatment with KOH, there was a further contraction of 30 mL. What is the composition of the mixture?

Text Solution

AI Generated Solution

To solve the problem, we need to determine the composition of a mixture of ethane (C2H6), ethylene (C2H4), and carbon dioxide (CO2) based on the given information about volume changes after combustion and treatment with KOH. ### Step-by-Step Solution: 1. **Define Variables:** Let: - \( a \) = volume of ethane (C2H6) in mL - \( b \) = volume of ethylene (C2H4) in mL ...
