Discovery Oxygen was first discovered by two scientists. One was a British Chemist Joseph Priestly who was given credit for the discovery in 1774. The other was a Swedish Chemist Carl Wilhelm Schiele who had also discovered it around the same time as Priestly. Yet Priestly was given credit because his work, and results were published. Priestly had first found this new element when he observed that mercuric oxide, on heating. Yielded a gas that caused a flame to burn faster.
He later found that it could support respiration and therefore he named it air. It wasn’t until a French chemist Antoine Laurent Lavoisier found it to be an elemental gas. It received it’s current name in s 1787 when several French Chemist’s including Lavoisier found that it formed acids from certain oxides of sulfur. The name oxygen literally means (acid former).
Oxygen in everyday surroundings Oxygen is the most abundant element found in the Earth’s crust. It makes up one-fifth of the air that surrounds the earth by volume.
Oxygen is present in many things and therefore it makes up 49. 5 % (by weight) of the earth’s crust. It also makes up 88. 81 of water by weight.
It has a boiling point of -183 F (-297 C), and a melting point of -360 F (-218 C).
Properties Oxygen is a colorless odorless and tasteless gas under ordinary conditions. It also has a pale blue color when it condenses in liquid state. Chemically oxygen can form compounds with almost any other chemical element. The elements when heated in a atmosphere containing oxygen form oxides..
The Essay on Million Years Earth Formed Volcanoes
The Earth formed when the sun and its forming of planets formed when a cloud of dust and gas condensed 4. 6 billion years ago. In large areas, iron sinks to the center forming the core. The Mantle is made up from primarily of the minerals olivine and pyroxene. It takes up 80% of the planet. The oceanic crust typically differ from continental crust because Earth's surfaces cooled below 100 degrees ...
