Calculate the average molar bond enthalpy of the carbon-hydrogen bond in a ch4 molecule.

415.825 kJ/mol.

Explanation:

Average enthalpy =

Now,

( SOURCE INTERNET)

Putting all these values above.

We get,

Average enthalpy=-1663.3 kJ.

Therefore, averagemolar bond enthalpy=

Hence, this is the required solution.

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
