Oxygen
Oxygen, symbol O, colorless, odorless, tasteless, slightly magnetic gaseous element. On earth, oxygen is more abundant than any other element.
Oxygen was discovered in 1774 by the British chemist Joseph Priestley and, independently, by the Swedish chemist Carl Wilhelm Scheele; it was shown to be an elemental gas by the French chemist Antoine Laurent Lavoisier in his classic experiments on combustion.
Large amounts of oxygen are used in high-temperature welding torches, in which a mixture of oxygen and another gas produces a flame of much higher temperature than is obtained by burning gases in air. Oxygen is administered to patients whose breathing is impaired and also to people in aircraft flying at high altitudes, where the poor oxygen concentration cannot support normal respiration. Oxygen-enriched air is used in open-hearth furnaces for steel manufacture. Most of the oxygen produced in the United States is used to make a mixture of carbon monoxide and hydrogen called synthesis gas, used for the synthesis of methanol and ammonia. High-purity oxygen is used also in the metal- fabrication industries; in liquid form it is of great importance as a propellant for guided missiles and rockets2.
I have chosen the element "Oxygen" because without Oxygen, human beings would not be able to live. Oxygen is probably the single most important element...
Carbon Dioxide (CO2) is a colorless gas, which was first discovered in 1577 by Van Helmont who detected it in the products of both fermentation and charcoal burning. CO2 is used in solid, liquid, and gas forms in a variety of industrial processes. These include: beverage carbonation, dry ice, welding and chemicals manufacturing. It is produced by the combustion of all carbonaceous fuels and can be recovered in an abundance of ways. It is widely used today as a by-product of synthetic ammonia production, fermentation, and from flue gases by absorption process. CO2 is also a product of animal metabolism and is important in the life cycles of plants and animals. It is present in the atmosphere only in small quantities (.03% by vol.)

All living cells need oxygen in order to carry out their various functions. These functions stop quickly if the supply
Cellular respiration is an important function for the body to obtain energy (Citovsky, Lecture 18). There are two types of cellular respiration; aerobic conditions and anaerobic conditions. Aerobic conditions are the cellular respiration occurred with oxygen while anaerobic conditions are cellular respiration occurred without oxygen. The most common cellular respiration is aerobic conditions where oxygen were supplied for phosphorylation (Campbell et al., pg 177). In human body, anaerobic conditions occurred when muscle cells are overworked and oxygen is depleted before it could be replenished (Citovsky, Lecture 19). This is a common phenomenon during exercise. The accumulation and production of lactic acid from anaerobic cellular respiration has been always a cause of muscle sore from intense exercise (Campbell et al., pg. 179).
Sulfur dioxide is a colorless gas which with a pungent odor. It will become liquid form when under pressure (heat) and will dissolves in water very fast or easily. The primary sources of sulfur dioxide are comes mainly from some activities such as burning of fossil fuel to provide electric power, process of making steel, coal-burning and others. However, it can also be released from the natural volcanic activity or volcanic eruption to the air. This gaseous can easily pose a threat to the living things such as human, animal and plant.
Hydrogen is a diatomic element that is in a gaseous form at room temperature. Its most identifying characteristic is the fact that it is highly explosive. It is the lightest element in the world, and has a lifting power of 8% more than that of helium. Hydrogen was used in airships and zeppelins for more than 20 years during the beginning of the 20th century. This practice stopped abruptly after the German airship Hindenburg disaster over New Jersey. It is used in fuel cells to create electricity, and to power cars and planes. Liquid hydrogen is mixed with liquid oxygen to form a cryogenic liquid that is burnt in Solid Rocket Boosters to power the space shuttle. Hydrogen is used to fill weather balloons because of its superb lifting power.
An element in chemistry is more than just an element; at least Chlorine is more than just an element. It is very useful in many ways that help people today. Chlorine is a common nonmetallic element belonging to the halogens; it is a heavy yellow irritating toxic gas; it is used to purify water and as a bleaching agent and disinfectant; occurs naturally only as a salt. People should know more about the uses of chlorine and why chlorine is used in many processes, for example; bleaching, and why we use it today. Everything has to start somewhere, and chlorine was produced many years ago.
Oxidation is the process of something being rusted or oxidized. This process has many ways to oxidize something. For example, when something is exposed to moisture it begins to oxidize. If a banana is is sitting out for too long, it will start turning brown and getting bruised up. That is what oxidation is. Technically the item doesn’t always have to turn into rust, like I said, it is many ways things can be oxidized. Oxidation is the loss of electrons in something. So like that banana it has lost its electrons so therefore it can no longer hold its fresh yellow color. It is going to oxidize because of the exposure to the moisture in the environment it is in. There would be no such thing as oxidation if it were not for oxygen.
‘When Breath Becomes Air’ is an exceptional book, written by Paul Kalanithi. The author takes us on a phenomenally sensitive journey, describing his days from childhood to the final days before his death by lung cancer. Paul was a true polymath, who even in his brief life, received noteworthy recognition for his research and studies as a scholar, a surgeon, a scientist and now - posthumously - as a writer. This memoir is a narrative of the trials that occur in both Paul’s stellar career and his refusal to give in to the illness which ultimately consumed him. Essentially, there's not much of a feat other than indefatigable resilience and a sincerity that endures long after the last word appears in this book which has many important things to tell us, about meaning in life when confronted with imminent mortality.
There are many human activities that affect the oxygen cycle, having a big impact on the photosynthesis process. Due to humans burning oil and other fuels, carbon dioxide gets released into the atmosphere, as well as having trees and plants removed, making fewer products to absorb carbon dioxide. Population is another big human activity that affects the oxygen cycle, by having more people there are not enough plants and trees to absorb carbon dioxide, making humans plant more trees and plants in order to get oxygen into the atmosphere.
Dairy industries use milk to produce a wide variety of processed products, including fluid milk, cream, butter and fermented dairy products like cheese and yogurt. Relative to other food sectors, dairy industries produce substantial environmental footprints at all steps of the value chain, from the production of feed for dairy cows to the distribution of milk and milk products. For instance, cheese is associated with a greenhouse gas emission of 5.9kg CO2 equivalents/kg, compared to 0.17kg CO2 equivalents/kg for peanut butter.
Carbon Dioxide is a colorless, odorless gas that occurs in small quantities in the earth's atmosphere naturally. The earth's ocean, soil, plants and animals release CO2. The formula of Carbon Dioxide is CO2. The CO2 molecule contains 2 oxygen atoms that each share 2 electrons with a carbon atom to form 2 carbon - oxygen double bonds. The atoms are arranged as so (OHT). This is called a 'linear molecule'.
Oxygen (O) is one of the most important ions present in the body, making up 61% of the body’s mass. It aids in the destruction of harmful bacteria, while preserving the bacteria that is beneficial for the body. Oxygen takes on its role, and transfers the bacteria absorbed into the lungs, to the cells, allowing for cell respiration. Oxygen allows for the replacement of old cells, protection of the new ones, production of energy from the food, and decomposition of other foods (“Oxygen and Human Body,” n.d.). Oxygen is also vital to produce an activity known as metabolism, which is ‘the sum of the physical and chemical processes in an organism by which its material substance is ...
