Rescurces previous l 7 of 26 l next Part C 2C2H6 7O2 (g) 4CO2 (g) 6H2O(g) In the equation, if 14 L of ethane (C2He) and 14 L of oxygen O2) combined and burned to completion, which gas will be leftover after the reaction, and what is the volume of that gas remaining? Enter the name of the gas followed by its volume in liters to the nearest whole number, separated by a comma. Gas, volume ethane,10 L Hints My Answers Give Up Review Part Correct when 14 L of ethane (CaHe and 14 L of oxygen (O2)burn. to completion, 10 L of ethane remains, which means that 4 L of ethane and 14 L of oxygen are burned Part D You just determined that when 14 L of ethane (C2He) and 14 L of oxygen (O2) combined and burned to completion, there is 10 L of excess ethane. In the reaction 4 L of ethane and 14 L of oxygen burn to completion. What volume of carbon dioxide (CO2) in liters is formed when 4 L of ethane and 14 L of oxygen burn to completion?

Explanation / Answer

a) The reaction of C2H6 with Oxygen is

2C2H6+ 14O2---- > 4CO2+ 6H2O

At constant temperature Volume is proportional to moles

Molar ratio of reactants as per the reaction C2H6 : O2 = 2:7= 4:14

gvien ratio C2H6:O2= 14:14

Ethanes is excess since required is only 4 and supplied is 14.

Excess ethane= 14-4 =10 L

4 moles of ethane reacts wtih 14 L of oxygen to produce 4*2= 8 L of CO2
