    Answer:

    Q=-50,307kJ

    Explanation:

    Hello there!

    In this case, since following reaction:

    C2H4+3 O2-> 2CO2 + 2H2O

    Has an enthalpy of combustion of ethene is about -1411.1 kJ/mol (can be found on goo gle), it is possible to calculate the total amount of energy that is released when 1000 grams of ethene are burned as shown below:

    Q=-1411.1 \frac{kJ}{molC_2H_4} *\frac{1molC_2H_4}{28.05gC_2H_4}*1000gC_2H_4 \\\\Q=-50,307kJ

    Best regards!
