SUMMARY

To produce 450 kJ of heat, 8.9 grams of ethylene (C2H4) must be burned. The combustion reaction of ethylene is represented as C2H4 + 3O2 ----> 2CO2 + H2O, with a heat of reaction (Delta H) of -1411 kJ. This indicates that burning 1 mole of C2H4 releases 1411 kJ of energy. The calculation confirms that the required mass of ethylene for the specified heat output is accurately determined.
