How does incomplete combustion occur?
A
Incomplete combustion, the reactant burns in oxygen, producing a limited number of products.
B
When there isn't enough oxygen to allow the fuel to react completely to produce carbon dioxide and water.
C
Incompletecombustion is a form of oxidation otherwise known as a fire, in which large amounts of heat and light energy are released, which often results in a flame.
D
Incomplete combustion is the slow, low-temperature, flameless form of combustion, sustained by the heat evolved when oxygen directly attacks the surface of a condensed-phase fuel.
