=__**The Combustion Of Hydrocarbons**__=

Combustion is a reaction where fuel burns in oxygen usually from air.Some common fuels are Coal, Propane and gasoline. The molecules in the fuel provide the energy, this energy is released in a combustion as thermal energy and light. Other products of combustion differ depending on the different types of fuels and how it was burned.Some common products which relate to this are dioxide, water and sometimes carbon monoxide.

The majority of fuels used today consist of organic compounds. A good example of organic compound is propane because, it is a molecular compound which contains one or more carbon-carbon bonds. Many organic compunds also consist of one or more carbon-hydrogen bonds.



Hydrocarbons are made up of two elements which are : hydrogen and carbon. Some common examples of hydro carbons are propane, C3H8, and butane, C4H10.Most hydrocarbons are extracted from coal, oil and natural gas. Hydrocarbons are usually burned down to be used as energy, most of this energy is used for transportation, home heating and electricity.

__Types Of Hydrocarbon Combustions__
All hydrocarbons are hot enough and have sufficient oxygen. We divide the compustion of hydrocarbons into two groups, either complet or incomplete which depend on the product that is formed.

A complete combustion of hydrocarbon happened when the supply of oxygen is enough. The products are energy, water vapour and carbon dioxide.

This is the unbalanced chemical equation for the combustion of a hydrocarbon, CxHy CxHy + O2(g) -> CO2(g) + H2O(g) + energy



A incomplete combustion of hydrocarbons occurs when the supply of oxygen is limited.Incomplete combustions cannot be represented by a single chemical reactiion.

This is a incomplete combustion of heptane, a hydrocarbon in gasoline:

C7H16(l) +7O2 (g) > 3C(s) + 2CO(g) + 2CO2(g) + 8H2O(g) + energy

2C7H16(l) +11O2 (g) > 14CO(g) + 8H2O(g) + energy



Hydrocarbons can impact our society buy putting substances that are dangerous into the air which is pollution. The toxins can also give us serious health problems. This video will give a breif description of what combustion of hydrocarbons are:

__Things I have learned__
__4 Super Glue Pratheep Logaranjan:__


 * super glue is also known as cyanoacrylate
 * This was first discovered by a man named Harry Coover from Kodak in WW2
 * Back in WW2 it was advertised under the name of "Flash Glue"

__8 Neutralizing Stomach Acids Kavishka__


 * Stomach acid is also known as Hydrochloric acid
 * You get hurtburns if the acids reach your esophagus
 * Stomach acid might seem harmful but in reality it is a high corrosive material that can eat through our tissues

__5) Iodine Shamarke Ali__


 * iodine comes from the word "iodes" which means violet in Greek
 * Iodine was first discovered by a french chemist Branard Courtois in 1811
 * A lack of Iodine leads to decreased production of thyroid hormones
