Question

2. Paraffin and gasoline are both hydrocarbons, and therefore have the same general

Answer 1

Answer:

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

$C_x H_y+ O_2 +N_2 \rightarrow CO_2 + H_2O + CO + HC + NO_x$

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
