The key role of oxygen and its compounds in important processes of life and industry

The chemical symbol for atomic oxygen is O, its atomic number is 8, and its atomic weight is In the first category are the higher plants and the photosynthetic bacteria. Depending on the number of hydrogen atoms that are replaced, the result The rates of reactions in this category are selectively controlled by enzymes in the organisms that facilitate the reactions.

Examples of divalent oxides are numerous among well-known substances such as water; carbon dioxide; aluminum oxide; silicon dioxide; the silicates, calcium carbonate or limestone; and sulfur dioxide. Molecular oxygen dissolved in water is required by aquatic organisms for their metabolic processes and is ultimately responsible for the oxidation and removal of organic wastes in water.

Oxygen is a gaseous chemical element in Group VA of the periodic table. Examples of important ternary oxides are the magnetic FERRITES, whose magnetic properties can be tailored, making them useful in computer memory units. The more economical, and therefore preferred, method for the commercial production of oxygen is the liquefaction and distillation of air.

Such oxidation reactions are, ultimately, the sources of energy for the higher plants and animals, are responsible for the cleansing of streams of biodegradable wastes, and are responsible for the natural decomposition of organic material.

This method is also used to produce oxygen on a commercial scale when a high-purity product is desired. The most common compounds of oxygen are those in which the element exhibits a valence of two.

Oxygen is formed by a number of nuclear processes that are believed to occur in stellar interiors. Two 18th-century scientists share the credit for first isolating elemental oxygen: It is used in the welding, cutting, and forming of metals, as in oxyacetylene welding, in which oxygen reacts with acetylene to form an extremely hot flame.

The gaseous oxygen produced in this fashion is shipped in pressurized cylinders or, as is often the case when large amounts are involved, through pipelines to nearby industrial plants. The oxidation of iron is a complex process involving impurities in the iron, as well as water and carbon dioxide.

Molecular diatomic oxygen is a fairly stable molecule requiring a dissociation energy the energy required to dissociate one mole of molecular oxygen in its ground state into two moles of atomic oxygen in its ground state of The surface of metals like aluminium and titanium are oxidized in the presence of air and become coated with a thin film of oxide that passivates the metal and slows further corrosion.

Essay/Term paper: Oxygen

There are very few elements for which no oxides are known, and there are several metallic elements such as titanium, vanadium, and praseodymium for which a wide variety of solid oxides exist. It is true that some oxides when dissolved in water do form acids; for example, sulfur dioxide forms sulfurous acid.

The rarer isotopes, principally the latter, find their major use in labeling experiments used by scientists to follow the steps of chemical reactions.Oxygen Oxygen and its compounds play a key role in many of the important processes of life and industry.
