Answer to Question #133422 in General Chemistry for Kay

Question

Suppose we have the following combustion reaction below. If we are given 2 moles of ethane

at STP, how many liters of CO2 are produced?

Answer 1

Ethane C2H6 combustion reaction is:

C2H6 + 3.5 O2 = 2 CO2 + 3 H2O

2 moles ethane produces 4 moles CO2, at STP the volume of CO2 will be:

4 mole * 22.4 L/mole = 89.6 L of CO2
