2. Paraffin and gasoline are both hydrocarbons, and therefore have the same general chemical formula CnHn+2. As such, paraffin and gasoline are similar in that both do
not contain oxygen. Compare the use of gasoline (which would be similar to
paraffin) versus ethanol as a fuel, considering that gasoline is a hydrocarbon
whereas ethanol also contains oxygen. Compare the use of gasoline versus ethanol
as a fuel, from the standpoint of efficiency, by comparing the amount of energy that
each contains on a per amount of fuel basis.

Paraffin combustion produces more energy per gram than ethanol fuel but paraffin fuel has a larger carbon footprint

Explanation:

Paraffin is also known by the standard chemical name alkane with a chemical formula for a paraffin given as  follows;

CₙH₂ₙ₊₂

While gasoline, also known as petrol, consists of light weight alkanes and alkenes

The heat of combustion of gasoline is about 47.3 kJ/g

The combustion of gasoline is incomplete as presented in the following equation

Example of complete combustion of octane, however, is given as follows;

2C₈H₁₈ + 25O₂ → 16CO₂ + 18H₂O  + Energy    

The source of paraffin is from petroleum

Ethanol fuel can be produced by the fermentation of Sugar

The heat of combustion of ethanol = 1366.91 kJ/mol = 29.664 kJ/g.

2CH₃OH + 3O₂  → 2CO₂ + 4H₂O  + Energy

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
