**Chemistry - Combustion**

The standard enthalpies of formation of gaseous propylene (C3H6) and propane (C3H8) are +20.4kJ/mol and -103.8 kJ/mol. Their respective combustion reactions may be written as follows, where one mole of either gas is consumed by oxyen to yield carbon dioxide and water. Propylen...
