Question

The combustion of ethene,C2H4,is an exothermic reaction. Use the information below to determine the amount of energy given off when 1000g of ethene is conbusted C2H4+3 O2-> 2CO2 + H20

Answer 1

`Q=-50,307kJ`

Step-by-step 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 (kJ)/(molC_2H_4) *(1molC_2H_4)/(28.05gC_2H_4)*1000gC_2H_4 \\\\Q=-50,307kJ`
