Element project (Oxygen) by Josephine Vang

History

jvang05 — 2022-11-16 17:42:19 UTC

It first appeared in the Earth's atmosphere around 2 billion years ago (in 1774). The people who discovered Oxygen was Joseph Priestley in Wiltshire, England and independently by Carl Wilhelm Scheele in Uppsala, Sweden. Priestley noted that a candle burning more brightly in it had made it easier to breathe. It is unknown how the other two found it but, Antoine Lavoisier also claims to have discovered Oxygen and he proposed that the new gas be called Oxy-gène, meaning acid forming, because he thought it was the basis of all acids. The way it is being used now is in hospitals to treat patients with a variety of respiratory issues.

Uses

Steel industry

jvang05 — 2022-11-16 19:42:18 UTC

It is being blown into the molten iron, reducing its carbon content from 4% to <0.5%.

Manufacture

jvang05 — 2022-11-16 19:55:09 UTC

It uses a wide range of chemicals including nitric acid and hydrogen peroxide.

Rocket propulsion

jvang05 — 2022-11-18 15:42:14 UTC

Its reaction generates tremendous heat, causing the water vapor to expand and exit the engine nozzles at speeds of 10,000 miles per hour.

Everyday life

jvang05 — 2022-11-22 22:11:33 UTC

We use Oxygen in our everyday life, to be able to breathe on earth. The way Oxygen is produced is by plants and trees. We breathe out Carbon Dioxide to plants for plants to give off Oxygen for us. Of course there is air pollution in the air, which makes it harder for us to breathe but the reason why there is so much pollution in the air is because of factory machine producing dirty smoke, making it harder to breathe and forest fires.

Combustion

jvang05 — 2022-11-22 22:18:03 UTC

When fuel is burned, oxygen in the combustion air chemically combines with the hydrogen and carbon in the fuel to form water and carbon dioxide, releasing heat in the process.

Compounds

Glycerol

jvang05 — 2022-11-22 22:55:45 UTC

It has Oxygen but, you can also explain that it also has carbon and it contains oxidise to carbon dioxide and the hydrogen is oxidised to water, in an exothermic reaction that is like a fuel being burned. The Oxygen in this compound is only used not by air but, from the Potassium Permanganate, KMnO4. https://www.chemistryworld.com/podcasts/glycerol/7682.articlehttps://www.chemistryworld.com/podcasts/glycerol/7682.article

Formaldehyde

jvang05 — 2022-11-22 22:59:11 UTC

A well-known reaction that allows the selective generation of acyl radicals by using Oxygen as a reagent. In industrial processes is carried out in bulk liquid aldehydes or organic solvents through the introduction of additives into the system. It is an important intermediate both in combustion and atmospheric chemistry. https://pubs.acs.org/doi/10.1021/acsomega.1c06375

Glutaraldehyde

jvang05 — 2022-11-22 23:30:45 UTC

Dissolve Oxygen is rapidly consumed by two processes; residual respiration and glutaraldehyde-induced chemical uptake. The nature of chemistry which consumes Oxygen during tissues fixation was investigated by studying model reactions of glutaraldehyde with amines and with homogenized tissue suspension.The initial rate of Oxygen consumed was sufficient to account for the stoichiometric conversion of the primary amines to pyridines. https://pubmed.ncbi.nlm.nih.gov/3127213/

Citric acid

jvang05 — 2022-11-22 23:38:34 UTC

A common constituent of plant and animal tissues. Citric acid is a colorless, translucent, odorless, crystalline or powdery material with a pleasantly acidic taste. https://www.encyclopedia.com/science-and-technology/chemistry/organic-chemistry/citric-acid

Acetic anhydride

jvang05 — 2022-11-22 23:47:11 UTC

It's the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis. A colorless liquid that smells strongly of acetic acid, which is formed by its reaction with moisture in the air. Goes through the central oxygen offers very weak resonance stabilization compared to dipole-dipole repulsion between the two carbonyl oxygens. https://en.wikipedia.org/wiki/Acetic_anhydride

Basic information

jvang05 — 2022-11-22 23:55:47 UTC

The element/atomic symbol name for Oxygen on the periodic table is just the letter "O". Oxygen's atomic number is number 8. The number of protons, neutrons, and electrons is 8 protons, 2 and 6 for electrons, and there is 8 neutrons.The percent for oxygen on earth is 21%.
