Calculate the bond dissociation energy needed to break all the bonds in a mole of carbon dioxide, co2.

Respuesta :

Draw Lewis dot structure for both. Since H is an exception to the octet rule H2O doesnt require any double bonds. The answer in this question is 920 kj/mol CO2 has 2 double bonds answer is 1464 kj/mol.The bond dissociation energy needed to break all the bond in a mole of carbon dioxide co2 is 920 kj/mol.

Answer:

-1598 kJ/mol

Explanation:

-2 x bond energy of C=O

C=O = 799 kJ/mol

-2 x 799 kJ/mol

-1598 kJ/mol
