I would like a helping hand for this exercise:
"A mixture of carbon monoxide, methane and nitrogen occupies a volume of 40 mL. Burning this mixture with an excess of oxygen, a volume concentration of 42 mL is observed after cooling at room temperature and together the formation of 36 mL of dioxide of carbon. Determine the volume of each component of the mixture. "
The first doubt is the reaction, I believe it is the following: CO + CH4 + N2 + O2 -> CO2 + N2 + H2O. But is impossible to balance.
Then I don't know how to proceed, because I don't have anything apart from the volumes and the molecular weights.
I also didn't understand if CO2 is part of those 42 mL or less.
Please enlighten me, thanks.
