Oxygen is a chemical element that largely forms part of the atmospheric and is widely recognized with the sustenance of life and survival of organisms. It has a formula of O2. As a chemical element, this substance has an atomic number of 8 and belongs to the chalcogen group on…

Identification by mass sets this element as the third-most abundant element in the universe after elements of hydrogen and helium. 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

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.
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).
Pinsk is in Belarus which was a part of the Great Russian Empire of that time. Weizman was a part of a large family and was one of the 15 brothers and sisters. His studies began at a traditional Hebrew school nearby and after finishing his lessons there he became a part of the high school at Pinsk.
He stated that if artists create the right atmosphere and eons that depict particular time, they could create beams of people that have the behaviour of waves. Julian Vos-Andreae is one of the artists who applied this theory in his works, quantum objects.
Hence, prompting to the emergence of numerous integrations of already discovered theories together with other fields like philosophy and physics. Mainly, philosophy and physics fields in this case usually try to question the validity as well as authenticity of certain theories, which up to date have contributed to the raising of other essential questions.
This would include the attractions exerted by one molecule of a molecular substance on another, such as the force of attraction between water molecules in ice ,the attractions between atoms of the noble gas elements, Helium through Radon, attractions between molecules of one substance and molecules of another, as when two liquids are mixed, or a molecular solid such as sugar is dissolved in a liquid and the attraction between molecules of one substance and ions of another, as when an ionic compound dissolves in a liquid.
The carrier gases can be helium which is an inert gas and nitrogen which is an un-reactive gas. The stationary phase is characterized by a column whose layer of liquid is microscopic or polymer found inside a metal tube or glass. Gas chromatograph is an instrument used to perform gas chromatography.
These brain functions are responsible for mental, emotional and motor skills. Irregular activity on neuro-transmitters in the brain would be one of the reasons for mental and emotional disorders that may affect person’s emotional and physical behavior. Changes in
son that people are most likely to flock to beaches and public swimming pools (though more the latter considering how much more accessible they are) to relax, unwind, have fun and, in short, chill. For sure, it should not be surprising that the single best way to beat the heat,
