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...

QUESTION A combustion reaction occurs when a fuel source reacts with oxygen (O) to form carbon dioxide (CO) and water (HO). Combustion reactions are frequently thought of as burning a fuel source. The fuel source is typically made of carbon and hydrogen or carbon, hydrogen, and oxygen. What is the missing equation coefficient that belongs in front of carbon dioxide (CO) in the combustion reaction for hexane, CH? CH (1) + 9 O(0) - CO, () + 6 H O(0)
