Get 10 Interesting Facts About Oxygen

Oxygen is one of the best-known gases on the planet, largely because it is so important for our physical survival. It is a crucial part of Earths atmosphere and hydrosphere, its used for medical purposes, and it has a profound effect on plants, animals, and metals. Facts About Oxygen Oxygen is atomic number 8 with the element symbol O. It was discovered by Carl Wilhelm Scheele in 1773, but he did not publish his work immediately, so credit is often given to Joseph Priestly in 1774.  Here are 10 interesting facts about the element oxygen. Animals and plants require oxygen for respiration. Plant photosynthesis drives the oxygen cycle, maintaining it around 21% in air.  While the gas is essential for life, too much of it can be toxic or lethal. Symptoms of oxygen poisoning include vision loss, coughing, muscle twitching, and seizures.  At normal pressure, oxygen poisoning occurs when the gas exceeds 50%.Oxygen gas is colorless, odorless, and tasteless.  Its usually purified by  fractional distillation of liquefied air, but the element is found in many compounds, such as water, silica, and carbon dioxide.Liquid and solid oxygen is pale blue.  At lower temperatures and higher pressures, oxygen changes its appearance from blue monoclinic crystals to orange, red, black, and even a metallic appearance.Oxygen is a nonmetal.  It has low thermal and electrical conductivity, but high electronegativity and ionization energy. The solid form is brittle rather than malleable or ductile. The atoms readily gain electrons a nd form covalent chemical bonds.Oxygen gas normally is the divalent molecule O2. Ozone, O3, is another form of pure oxygen.  Atomic oxygen, which is also called singlet oxygen does occur in nature, although the ion readily bonds to other elements. Singlet oxygen may be found in the upper atmosphere. A single atom of oxygen usually has an oxidation number of -2.Oxygen supports combustion.  However, it is not truly flammable!  It is considered an oxidizer. Bubbles of pure oxygen dont burn.Oxygen is paramagnetic, which means it is weakly attracted to a magnet but doesnt retain permanent magnetism.Approximately 2/3 of the mass of the human body is oxygen. This makes it the most abundant element, by mass, in the body.  Much of that oxygen is part of water, H2O. Although there are more hydrogen atoms in the body than oxygen atoms, they account for significantly less mass. Oxygen is also the most abundant element in the Earths crust (about 47% by mass) and the third most common ele ment in the Universe. As stars burn hydrogen and helium, oxygen becomes more abundant.Excited oxygen is responsible for the bright red, green, and yellow-green colors of the aurora. Its the molecule of primary importance, as far as generating bright and colorful auroras.Oxygen was the atomic weight standard for the other elements until 1961 when it was replaced by carbon 12. Oxygen made a good choice for the standard before much was known about isotopes because although there are 3 natural isotopes of oxygen, most of it is oxygen-16. This is why the atomic weight of oxygen (15.9994) is so close to 16. About 99.76% of oxygen is oxygen-16.

Arthur Millers The Crucible Essay - 1231 Words

Arthur Millers The Crucible The Crucible is based on the Salem Witch Trials in 1692. In act 1 the audience find out that John Procter had an affair with Abigail Williams, who was dancing in the woods, and that she still has feelings for him. When John denies their love Abigail starts accusing people of witchcraft. Act 2 is when we meet Elizabeth Procter who gets arrested on suspicion of witchcraft. In act 3 John goes to court trying to free his wife and the others but without much luck as he gets accused of mixing with the devil. He is then arrested.

He does try to please Elizabeth, If the crop is good Ill buy you George Jacobs heifer. How would that please you? He asks first to see if he would be doing the right thing. After he says this he gets up and kisses Elizabeth but she would probably show no real reaction so he sits back down disappointed. Elizabeth then starts to tell John to go to Salem but Arthur Miller suggests she is scared about angering John. After this happens Marry Warren, John and Elizabeths maid, comes back from Salem after being forbidden to go there. John is very angry at this point and although no violence had taken place he is very close to going over the edge. An actor would show this by shouting and lots of quick elaborate movements. Also he grabs Mary. Mary then hands Elizabeth a rag doll as if to apologise for doing wrong. Mary then tells John and Elizabeth that Abigail has been accusing people of witchcraft and what was 14 is now 39 people arrested. She then goes to say how Elizabeth had been accused but she had been cleared by her saying, I never see no sign you ever sent your spirit out to hurt no one. Arthur Miller phrased this quote like this because it only says she didnt send out her spirit to hurt any one not she didnt send out her spirit at all which dose not put her completely in the clear. Elizabeth asked who accused her but Mary tells her that she isShow MoreRelatedArthur Millers The Crucible1002 Words   |  4 Pagesreligious authority; this is now deemed unconstitutional in America.

Dr. Terry W. Thompson - 980 Words

Dr. Terry W. Thompson, an influential professor at the College of Liberal Arts and Social Sciences at Georgia Southern University, skillfully analyzes the failed father and son relationships in his essay â€Å"Shelley’s Frankenstein.† Dr. Thompson offers background information on subtleties within the novel, which are not easily associated without the knowledge of historical figures and Greek mythology. He focuses this vast background knowledge on connecting the failed father and son relationship of Victor Frankenstein and the creature. While many would agree that Mary Shelley’s references to historical figures excellently support the failed father and son relationship theme in the book, Dr. Thompson’s essay is weakened by failing to expound on one of his examples and by omitting several other father and son relationships within the novel. The majority of Dr. Thomas’ essay is spent focused on connecting the historical figure, King Arthur to Victor F rankenstein. While Victor and his friend Henry Clerval are visiting the city of Edinburgh, Victor marvels at a â€Å"romantic castle† and the famous â€Å"Arthur’s Seat† (Shelley, ch. 17). Dr. Thompson explains that King Arthur had an adulterous affair, which produced an illegitimate son named Modred (85). Instead of loving and nurturing his son, King Arthur attempts to drown the child (Thompson 86). Like Arthur, Victor created an illegitimate child in an unnatural way.

In both cases, individuals and companies dazzled by the unlimited commercial possibilities of new invention of technologies. The flood of the capital led to enormous overflow and devastating scenario for the entire industry (G. Carr, 2003). 2.3 Important points: As important points there are some issues came out form the study- Spending needs to be less. Studies indicate that there are very few companies who posted good result with a huge amount of capital. Flow, does not lead. Waiting for a technologically invented product can cause prevention of having technologically flawed product. Need to focus on the vulnerabilities rather than opportunities (Davis, 2003). 2.4 Approach used: Approaches are used here buy gaining understanding upon how to lessen the expenditure or overflow of the capital. Strategies must be used there in order to plan the budget and overall organizational to do list. 2.5 Issues and questions I would like to bring: How moors law is indicates the path to think strategically about the investment? How the vulnerabilities need to be identified? References Davis, C. (2003). Technologies methodologies for evaluating information technology in business. Hershey, PA: IRM Press. Carr, N. (2003).
