Answer : The energy produced from the combustion of 5 mole
is 
Solution : Given,
Released energy = 803 KJ
The balanced combustion reaction is,

As per the question,
1 mole of
releases energy = 803 KJ
5 mole of
produced energy = 
Therefore, the energy produced from the combustion of 5 mole
is 
The chemical bonds in CH4 are all single bonds. C only can bond 4 times because it needs 8 electrons in it's outer shell and only has four right now. The bonds represented are all single bonds because there are two electrons present on each side of the carbon. Two electrons, in this case, equals one bond.
