Given
- incomplete combustion of atom X gives the following:
- X + O2  1,5 . 10-2 mols CO2 + 4,5 . 10-2 mols CO + 4,5 . 10-2 mols H2O

Question: which atom is x?
a/ C2H2
b/ C4H6
c/ C4H8
d/ C4H10

The answer is b, but how do you solve this question? How do you know/calculate which atom X is?

Hydrocarbon X !
Count moles of atoms C and H and find ratio

And if it were a complete combustion of the hydrocarbon X, do you have to count the amounts of O2 as well in that situation? Or when do you have to consider the ratio of O2 as well?
