Chemical Equation Chemical Reaction:
 C10H8+ 12 O2 → CO2 + 4H2 O (Naphthalene) Combustion

Introduction of the Product:
Naphthalene is an organic compound with formula C10H8. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings. It is best known as the main ingredient of traditional mothballs.

It’s formed by 10 moles of C + 4 moles of H2 or simply C10H8 + 12 moles of O2.

Combustion: Organic compound + O2 H2O + CO2 

With the given elements, it is seen that the chemical reaction formed is combustion. Because in a complete combustion reaction, a compound reacts with an oxidizing element, such as oxygen or fluorine, and the products are compounds of each element in the fuel with the oxidizing element.

Importance of Study:
* The primary use for naphthalene is in the production of phthalic anhydride.  However, o-xylene is replacing naphthalene as the preferred raw material for phthalic anhydride production. * Other uses of naphthalene include carbamate insecticides, surface active agents and resins, as a dye intermediate, as a synthetic tanning agent, as a moth repellent, and in miscellaneous organic chemicals. It is also found in Toilet bowl deodorizers and new plastic items. Naphthalene, which is used to make moth balls or the anti-insect balls your mother put in the closet, was derived from the word “naphtha” meaning volatile, flammable, hydrocarbon liquid.

Exposure to large amounts of naphthalene may damage or destroy red blood cells. Humans, in particular children, have developed this condition, known as hemolytic anemia, after ingesting mothballs or deodorant blocks containing naphthalene. Symptoms include fatigue, lack of appetite, restlessness, and...
