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, C

C

But when it is balanced equation the amount of O

C

4.5 mol* 7/2 = 15.72 mol

_{2}H_{6}, undergo combustionaccording to the unbalanced equation the amount of O_{2}is the samethat amount of ethane.C

_{2}H_{6}+ O_{2}----> CO_{2}+ H_{2}O, so it is 4.5 mol of O_{2}But when it is balanced equation the amount of O

_{2}is next,C

_{2}H_{6}+ 7/2 O_{2}----> 2CO_{2}+ 3H_{2}O4.5 mol* 7/2 = 15.72 mol
