As with any combustion reaction, the products of combusting a hydrocarbon fuel (CxHy) with oxygen (O2) are carbon dioxide (CO2) and water (H2O). A mass of 13.87 g for an unknown fuel was combusted in a reaction vessel containing an unknown amount of oxygen. At the end of the reaction, there still remained 13.80 g of the fuel as well as 0.1144 g of water and 0.2096 g of carbon dioxide. The oxygen was completely consumed during the reaction. How...
