* Oxygen balance

Oxygen is more electronegative than carbon, thus the hydrogens alpha to ethers are more acidic than in simple hydrocarbons.

Oxygen is a common oxidizing agent, but not the only one.

Oxygen gas is fed through the cathode, where it reacts with electrons to create oxygen ions.

Oxygen is not shown in this model, but, for each of the iron atoms, it binds to the iron ( red sphere ) in the flat heme.

Oxygen is a common constituent of the moon's crust, and is probably abundant in most other bodies in the Solar System.

Oxygen is used to remove an amine group from a molecule, resulting in the corresponding aldehyde and ammonia.

Oxygen ( ) is a chemical element with symbol O and atomic number 8.

Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element that readily forms compounds ( notably oxides ) with almost all other elements.

Oxygen is a strong oxidizing agent and has the second-highest electronegativity of all reactive elements, second only to fluorine.

Oxygen is toxic to obligately anaerobic organisms, which were the dominant form of early life on Earth until began to accumulate in the atmosphere.

Oxygen was independently discovered by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774, but Priestley is often given priority because his work was published first.

Oxygen is produced industrially by fractional distillation of liquefied air, use of zeolites with pressure-cycling to concentrate oxygen from air, electrolysis of water and other means.

Oxygen is also commonly present in polymer backbones, such as those of polyethylene glycol, polysaccharides ( in glycosidic bonds ), and DNA ( in phosphodiester bonds ).

Oxygen is a waste product of light-dependent reactions, but the majority of organisms on Earth use oxygen for cellular respiration, including photosynthetic organisms.

Neighbours, which is celebrated its 20th anniversary in 2005, was aired on the US channel Oxygen in March 2004, however it attracted few viewers, perhaps in part because it was scheduled opposite well-established and highly popular US soap operas such as All My Children and The Young and The Restless, and due to low ratings it was cancelled shortly afterwards.

* April 5 – Oxygen is liquefied for the very first time.

Oxygen is a useful standard, as, unlike hydrogen, it forms compounds with most other elements, especially metals.

Oxygen is shown in red, silicon in pink, and magnesium / iron in blue.

Oxygen ( bound to hemoglobin in red blood cells ) is the most critical nutrient carried by the blood.

Oxygen therapy is often necessary in severe respiratory disease such as pulmonary fibrosis.

Oxygen is required by all aerobically respiring plants and animals and it is replenished in daylight by photosynthesizing plants and algae. As they cannot photosynthesis, the method of plants produces energy, and oxygen.

Oxygen will be supplied through tubes attached to the nose and ventilation equipment may be used to assist with breathing.

Oxygen is used in aerobic respiration, the main source of the seedling's energy until it grows leaves.

There have also been modifications to the Fick method where respiratory oxygen content is measured as part of a closed system and the consumed Oxygen calculated using an assumed oxygen consumption index which is then used to calculate Q.

In the 1890s, the Danish scientist and inventor Poul la Cour constructed wind turbines to generate electricity, which was used to produce hydrogen and Oxygen by electrolysis and a mixture of the two gases was stored for use as a fuel.

Oxygen sensors are used to monitor the exhaust oxygen content before and after the catalytic converter and this information is used by the Electronic control unit to adjust the fuel injection so as to prevent the first ( NO < sub > x </ sub > reduction ) catalyst from becoming oxygen-loaded while ensuring the second ( HC and CO oxidization ) catalyst is sufficiently oxygen-saturated.

Oxygen rebreathers are also sometimes used when decompressing from a deep open-circuit dive, as breathing pure oxygen makes the nitrogen diffuse out of the blood more rapidly.

Oxygen rebreathers are no longer commonly used in diving because of the depth limit imposed by oxygen toxicity.

Oxygen sensors are sometimes used as a safety precaution when working with liquid nitrogen to alert workers of gas spills into a confined space.

3DLABS was the name of the fabless semiconductor company that originally developed the GLINT and PERMEDIA high-end graphics chip technology that was used on many of the worlds leading computer graphics cards in the CAD and DCC markets, including its own Wildcat and Oxygen cards.

Oxygen carrying capacity is often the target of ergogenic aids used in endurance sports to increase hematocrit, such as through blood doping or the use of erythropoietin ( EPO ).

* Oxygen Index, the ratio oxygen: carbon used in Van Krevelen diagrams by petroleum geologists for the assessment of kerogen maturity

Oxygen is used as a medical treatment in both chronic and acute cases, and can be used in hospital, pre-hospital or entirely out of hospital, dependant on the needs of the patient and the views of the medical professional advising.

Oxygen is widely used in emergency medicine, both in hospital and by emergency medical services or advanced first aiders.

A home oxygen concentrator in situ in an emphysema patient's house. Oxygen can be separated by a number of methods, including chemical reaction and fractional distillation, and then either used immediately or stored for future use.

Oxygen therapy can also be used as part of a strategy for delivering drugs to a patient, with the usual example of this being through a nebulizer mask, which delivers nebulizable drugs such as salbutamol or epinephrine into the airways by creating a vapor-mist from the liquid form of the drug.

Oxygen first aid has been used as an emergency treatment for diving injuries for years.

This does not sit well with the JSDF, who fear that the Oxygen Destroyer, which was used to kill the original Godzilla, may have disastrous side effects.

Oxygen primary ions are often used to investigate electropositive elements due to an increase of the generation probability of positive secondary ions, while caesium primary ions often are used when electronegative elements are being investigated.

) because ordinary fuel cannot be used there, due to absence of environment that supports combustion ( On earth, we have an environment of Oxygen, a supporter of combustion ). Cryogenic fuels most often constitute liquefied gases such as liquid hydrogen.

It has been noted in other film reviews that while they are wearing gas masks, but gas masks would include goggles to protect the eyes ; due to the thin Martian atmosphere, the explorers are actually wearing military Oxygen Breathing Apparatuses ( OBA ) like those used by military firefighters.
