| Question | Answer |
|---|---|
| what happens when hydrocarbon fuels are combusted | they release energy |
| explain the combustion of hydrocarbons | carbon and hydrogen atoms in the fuel react with oxygen and become oxidised, if oxygen is unlimited, it produces CO2 and water, called complete combustion |
| balance the combustion reaction of methane: CH4 + O2 --> CO2 + H20 | 2O2, 2H2O |
| balance the combustion reaction of ethane: C2H6 + O2 --> CO2 + H2O | 2C2H6, 7O2, 4CO2, 6H2O |
| balance the combustion reaction of propane: C3H8 + O2 --> CO2 + H2O | 5O2, 3CO2, 4H2O |
| balance the combustion reaction of butane: C4H10 + O2 --> CO2 + H2O | 2C4H10, 13O2, 8CO2, 10H2O |
