Answer:

When a fuel undergoes complete combustion, it releases the maximum amount of energy from the fuel being reacted. Incomplete combustion is also a reaction between oxygen and fuel but the products are carbon monoxide, water and carbon

Answer:

What is Complete Combustion?

Combustion reactions are reactions which involve oxygen gas and are exothermic. Exothermic reactions are chemical reactions in which energy is released in the form of light or heat. Combustion most commonly refers to the burning of hydrocarbons in the presence of oxygen gas.

Combustion is a chemical reaction that involves a reactant and an oxidant which is typically oxygen, with products including heat and energy being produced.

Combustion reactions are redox (reduction – oxidation) reactions in which the reductant and oxidant react to produce heat, energy and often flame. The reductant is referred to as the fuel and oxidant as the gas.

In complete combustion there is sufficient oxidant for the reaction to occur.

A complete combustion of a hydrocarbon with oxygen as the oxidant will produce carbon dioxide and water. 2C8H18 + 25O2  18CO2 + 16H20

Another example of complete combustion is the organic compound methanol: CH3OH + O2  CO2 + 2H20

Combustion is not only important in our everyday lives in the production of energy, but also in keeping us alive. When the cells of our bodies break down sugar (glucose) to release energy they do so by a complete combustion reaction in aerobic cellular respiration.

During aerobic respiration, glucose is combusted in the presence of oxygen to produce carbon dioxide, water and ATP (energy). A small quantity of heat is also generated in the process since this is an exothermic reaction.

The formula for this is: C6H12O6 + 6O2  6CO2 + 6H2O

Complete combustion is often indicated by the production of a blue flame, and since all the reactants are completely burned, no smoke is produced which means that environmentally complete combustion is much cleaner than incomplete combustion in terms of pollution.
