Newly Discovered Star Has an Almost Pure Oxygen Atmosphere The star is unique in the known pool of 32,000 white dwarf stars, and is the only known star of any kind with an almost pure oxygen atmosphere. The new white dwarf has a mouthful of a name—SDSSJ124043.01+671034.68—but has been nicknamed 'Dox' (pronounced Dee-Awks) by Kepler's team.

- Oxygen is the most abundant element in the earth's crust and in the body. The body's 43 kilograms of oxygen is found mostly as a component of water, which makes up 70% of total body weight.he table below gives the amount of each chemical element found in the human body, from most to least abundant. For each element, there is the amount in mass units in an averge (70-kilogram) person, the volume of the element, and the length of the side of a cube that would contain that amount of the pure element.

- Dissolved Oxygen (DO) is found in microscopic bubbles of oxygen that are mixed in the water and occur between water molecules. DO is a very important indicator of a water body's ability to support aquatic life. Fish breathe by absorbing dissolved oxygen through their gills.

- Oxygen Meters. At PCE Instruments you will find a range of oxygen meters for water. There are oxygen meters for both pure oxygen content and for oxygen concentration in water available. Oxygen meters can be either water-proof, or equipped with an internal data storage or as a classic edition for laboratorial applications.

- Without it, we would die within minutes. Pure air is a mixture of several gases that are invisible and odourless. It consists of about 78% nitrogen, 21% oxygen, and less than 1% of argon, carbon dioxide, and other gases — as well as varying amounts of water vapour.

Oxygen By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standardized conditions for temperature and pressure, two atoms of the element bind to form dioxygen, a diatomic gas that is colorless, odorless, and tasteless, with the formula O 2.xygen constitutes 49.2% of the Earth's crust by mass and is the major component of the world's oceans (88.8% by mass). Oxygen gas is the second most common component of the Earth's atmosphere, taking up 20.8% of its volume and 23.1% of its mass (some 10 15 tonnes).

- Pure iron refers to iron that is all iron with no other things in it. We find a lot of things around us made of iron, but the iron has impurities in it. About the only place… we find iron in pure form is in iron (like filings, powder or other form) that is supplied to a chemical laboratory as reagent grade.

Is it dangerous to breathe pure oxygen? No its not dangerous to breath pure oxygen(Under normal conditions).... Oxygen is the primary thing that you need in order to live..... Pure Oxygen(100%) however does become dangerous to breath at pressures greater than 1.6 atmospheres when diving in water (about 20 feet deep) at this depth pure oxygen becomes toxic and it causes Oxygen Narcosis resulting in unconscousness and other symptoms...

Dissolved Oxygen In limnology (the study of lakes), dissolved oxygen is an essential factor second only to water itself ¹. A dissolved oxygen level that is too high or too low can harm aquatic life and affect water quality. Non-compound oxygen, or free oxygen (O2), is oxygen that is not bonded to any other element. Dissolved oxygen is the presence of these free O2 molecules within water.The bonded oxygen molecule in water (H2O) is in a compound and does not count toward dissolved oxygen levels.

How Much Breathable Oxygen Gas Is There In The Atmosphere? Water is one oxygen atom combined with two hydrogen atoms into H2O. Water is eighty-nine percent oxygen by weight, and the surface of the planet has far more water than land. So in another sense oxygen is everywhere on earth: in our lungs, under our feet and in our swimming pools! Share.

Oxygen Oxygen is one of the basic chemical elements. In its most common form, oxygen is a colorless gas found in air. It is one of the life-sustaining elements on Earth and is needed by all animals.Oxygen is also used in many industrial, commercial, medical, and scientific applications.hen oxygen is cooled below -297° F (-183° C), it becomes a pale blue liquid that is used as a rocket fuel. Oxygen is one of the most abundant chemical elements on Earth. About one-half of the earth's crust is made up of chemical compounds containing oxygen, and a fifth of our atmosphere is oxygen gas.

What is a pure substance? A pure substance is a substance that cannot be separated by physical means. eg. filtration, evaporation, distillation or chromatography. Examples of pure substances include water, gold, glucose, carbon dioxide, oxygen and hydrogen. A pure substance is made up of one type of particle. The particle that makes up water is H 2 O. The particle that makes up carbon dioxide is CO 2.

Key Words The structure shown above is oxygen's cubic crystal element structure. Oxygen exists in all three forms-liquid, solid, and gas. The liquid and solid forms are a pale blue colour. However, oxygen gas is colourless, odourless, and tasteless.The elemental structure is a cubic crystal shape. Oxygen changes from a gas to a liquid at a temperature of 182.96°C, and then can be solidified or frozen at a temperature of -218.4°C. Oxygen exists in all three allotropic forms.owever, oxygen gas is colourless, odourless, and tasteless. The elemental structure is a cubic crystal shape.
