A producer gas made from coke has the following composition by volume:
CO - 28.0%

CO2 - 3.5 %

O2 - 0.5 %

N2 - 68.0 %
(Total-100.0%)
This gas is burned with such a quantity of air that the oxygen from the air is 20% in excess of the net oxygen required for complete combustion. If the combustion is 98% complete, calculate the weight and composition in volumetric per cent of the gaseous products formed per 100 lb of gas burned.
