Propane is a three-carbon alkane with the molecular formula C3H8. It is normally a gas, but compressible to a transportable liquid. Propane was first identified as a volatile component in gasoline. It was discovered by Walter O. Snelling of the U.S. Bureau of Mines in 1910. On March 31, the New York Times reported on Snelling's work with liquefied gas and said that "...a steel bottle will carry enough gas to light an ordinary home for three weeks." This means that propane can be transported in a tank.

Where it is found.

Propane is produced as a by-product of natural gas processing and petroleum refining.

5 Facts

1. The density of liquid propane at 77 °F is 0.493 g/cm3, which is equivalent to 4.11 pounds per U.S. liquid gallon or 493 grams per litre.

2. Propane is heavier than air.

3. Propane is the third most popular gas used in vehicle transportation- with quicker refills, cost effective prices, and cleaner handling. Not only is propane cleaner than most other fuels, it is environmentally friendly, too.

4. More than 14 million households use propane to fuel their furnaces, water heaters, air conditioners, and a lot more.

5.Propane users are helping to reduce ozone depletion because of propane's ability to replace chlorofluorocarbon and hydro fluorocarbon refrigerants.

Bible verse

Exodus 13:21

And the Lord went before them by day in a pillar of cloud to lead the way, and by night in a pillar of fire to give them light, so as to go by day and night.

Why I choose this molecule?

I chose propane because it has many uses and is utilized almost every day. I never realized how much propone people use and how many different ways it could be used.
