Representatively by dry air volume, oxygen forms about 20.9476% (209,460 ppmv) of the atmosphere by volume at the sea level temperatures of 150C; thus, making it the third largest compound.
Understanding the composition of oxygen and its molecular composition is essential in its incorporation to further chemical uses given that it is a primary atmospheric industrial gas product. For instance, given that one has 32 grams of oxygen, this will be equivalent to one mole of Oxygen gas while 16 grams of the same would be a representation of Oxygen element. This implies that the molecular mass of Oxygen is 32 grams while its atomic mass is 16 grams. By ratio compared to dry air, Oxygen forms about 23.20% of the atmospheric air by weight and has a boiling point of -182.950C.
Oxygen forms about 85% of the earth’s elements such as oceans, and is a component of most minerals and rocks given that 46% of these rocks and minerals comprises of Oxygen. Subsequently, the compound forms about 60% of the human body mass.
Oxygen as a chemical compound possess distinct properties such as being colorless, being tasteless and odorless. Oxygen also has the property of being poorly soluble in water. A particular gravity of 1.105 is enough to make oxygen be slightly heavier than air. When the Oxygen is cooled to its boiling point of -1830C, it turns appearance and becomes a transparent, pale blue liquid that has a slightly heavy weight than water.
Oxygen as a compound can react with all elements, excluding the inert gases resulting in the formation of oxides through a varied reaction rate (oxidation). Even though oxygen in itself is non-flammable, it enhances the combustion process; thus, enabling all flammable materials to burn vigorously. The use of oxygen in industrial ...Download file to see next pagesRead More

The Chemistry of Biodiesel Production
No other fuels are: so abundant, have such a high energy and power density, store energy so efficiently and conveniently, release their energy so readily, have existing infrastructure, and are so easily transported (Eberhardt 2). With no alternative that can match the merits of petroleum fuels yet identified, (Eberhardt 25) sees hydrocarbon-based fuels as being among the more likely alternatives to meet the increasing energy demands for heavy-duty vehicles.

Physical Science
Nonliving things can also be found in nature. Water and earth, for example, are nonliving things which can be readily found in almost all parts of the natural environment. The physical sciences have been created for the specific purpose of gathering and organizing knowledge about the nonliving natural world (Hewitt, Suchocki and Hewitt 8).
