What is the difference between incomplete and complete combustion?

 
Combustion is a type of chemical reaction that usually involves oxygen. For combustion to occur, oxygen combines with another compound to form water and carbon dioxide. Combustion usually results in the production of light and heat in the form of a flame. There are two types of combustion: incomplete and complete combustion. Incomplete combustion is the type of combustion in which there is not enough oxygen or a high enough temperature for the carbon to turn into carbon dioxide. This can sometimes lead to the production of carbon monoxide, which is very harmful to the human body. Incomplete combustion will produce a yellow flame. An example of an incomplete combustion is burning paper because there are remnants of ash. Complete combustion is when the substance is completely burned and only carbon dioxide and water remain. many magicians use paper with extra oxygen molecules. This special paper will burn completely leaving no traces when burned. Complete combustion produces a more orange or blue flame.
