Question #24794
a. If 4.5 mol of ethane, C2H6, undergo combustion according to the unbalanced equation C2H6+O2---->CO2+H2O, how many moles of oxygen are required? b. How many moles of each product are formed?
Expert's answer
If 4.5 mol of ethane, C2H6, undergo combustionaccording to the unbalanced equation the amount of O2 is the samethat amount of ethane.
C2H6 + O2 ----> CO2 + H2O, so it is 4.5 mol of O2
But when it is balanced equation the amount of O2 is next,
C2H6 + 7/2 O2 ----> 2CO2 + 3H2O
4.5 mol* 7/2 = 15.72 mol
C2H6 + O2 ----> CO2 + H2O, so it is 4.5 mol of O2
But when it is balanced equation the amount of O2 is next,
C2H6 + 7/2 O2 ----> 2CO2 + 3H2O
4.5 mol* 7/2 = 15.72 mol
