Answer:
5998kJ
Explanations:
Given the reaction between ethanol and oxygen expressed as:
[tex]C_2H_5OH+3O_2\rightarrow2CO_2+3H_2O[/tex]
For the product
We have 2 moles of CO2 and 3 moles of water. The total bond energy in the product is expressed as:
[tex]\begin{gathered} \triangle H_p=2(2C=O)+3(2O-H) \\ \triangle H_p=4(799)+6(467) \\ \triangle H_p=3196+2802 \\ \triangle H_p=5998kJ \end{gathered}[/tex]
Hence the total energy transferred to build all the bond energy in the product is 5998kJ
