PROPANE BY ANYA AND JORDAN :)

The chemical reaction we chose to do was propane, which is also known as liquefied petroleum gas. The formula to make propane is C3H8. It is produced from both natural gas processing and crude oil refining. The chemical is nontoxic, colorless and odorless. The chemical is used and sold as a fuel. It can fuel a barbecue stove or a motor vehicle. Propane is used to fuel motor vehicles because it is at liquid state at room temperature and moderate pressure. This allows fast refill times, affordable fuel tank construction, and ranges comparable to gasoline. In some places propane is used in water heaters, laundry driers or other heat producing appliances. Propane is and important raw material for the ethylene petrochemical industry. When propane is broken down in hot tubes to form ethylene, the product propylene is formed which is also an important product. Because propane has a boiling point of -41.1 degrees C, it liquefies under elevated pressures easily. That is why the chemical is held in cylinders and tanks. Since propane is stored in portable tanks, it can be taken and used anywhere.

Propane can also form many other substances when it reacts with other compounds in a combustion reaction. It can form carbon dioxide and water when it is heated to a certain temperature. Water and carbon monoxide can be formed also, when propane is fully heated. Formula for Carbon Dioxide and Water: Formula for Carbon Monoxide and Water: 2**C3H8** + 7O2 → 6CO + 8H2O + heat
 * C3H8 ** + 5O2 → 3CO2 + 4H2O + heat

Propane has other uses besides powering things like barbeque stove or motor vehicles; it is growing rapidly in non- industrial areas of the world. Propane is replacing wood and other traditional fuel sources in such places, where it is now sometimes called "cooking gas". The Servel Company, used propane-powered refrigerators, and say they are highly efficient, do not require electricity, and have no moving parts. Other North American industries using propane include glass makers, brick kilns, poultry farms, and other industries that need portable heat.

There can also be risks to propane usage as well though. Since propane is heavier than air, if a leak in a propane fuel system occurs, the gas will have a tendency to sink into any enclosed area and thus poses a risk of explosion and fire.
