Nitrogen cycle

available to medical science since 1935. These treatments are for respiratory diseases like bronchiolitis, chronic obstructive pulmonary disease (COPD), asthma, and croup. Helium replaced the role of nitrogen, which was used in earlier attempts as a carrier gas, because it is less dense than nitrogen and allows easier breathing and the absorption of oxygen into the bloodstream occurs more readily. The use of heliox therapy is also done for conditions that do…

AHCSOL303 Assignment 3- soil amelioration report 1.i have a soil that does not absorb water, and when i water it the water pools on the surface and does not infiltrate. What is wrong with my soil? The soil could either be hydrophobic or heavily compacted. Hydrophobic soil is where the surface tension does not allow for infiltration of water because of a waxy layer, which cause the water to form into little beads and can form a pool on the surface. Heavily compacted soil is soil that has…

While trying to find a life lengthening elixir Chinese alchemists invented the deadliest powder in the world. In the 9th Century Chinese alchemists were trying to find a potion of immortality. However they ended up finding a potion of death unlike anything else. The first ever mixture was 75 percent saltpeter or more commonly known as potassium nitrate, 15 percent sulfur, and 10 percent charcoal. After the invention of gunpowder the Chinese people initially used it for fireworks. It was not…

Biogeochemical cycles are the way in which nutrients move through the earths system. It is a pathway for chemical elements to move through biotic and abiotic factors. The ocean contributes largely to these cycles as it acts as a reservoir or sink for the accumulation of nutrients. Even water itself is recycled through precipitation, evaporation and condensation. This is a typical cycle that can be observed for the vital elements of life such as carbon and nitrogen. Microbes are essential to the…

ammonia gas is produced from hydrogen gas and atmospheric nitrogen. Nitrogen is one of the most abundant elements in the atmosphere, but plants are unable to reap the benefits that nitrogen has to offer because of their inability to break the triple bonded diatomic molecule. This element has been found to promote plant growth and increase crop yield, but it is only of use when the triple covalent bond between the atoms is broken. Although nitrogen may be abundant, it can serve no benefit to…

When nitrogen is applied to the ground in the method of fertilizer to help the agriculture crops grow, it can be washed off by rain or can seep down into the groundwater. If that water is used as a source of drinking water, the excess nitrogen in that water consumed by humans can cause cancer or respiratory problems. If there is too much nitrogen in bodies of water, it can result in the eutrophication and result in too much…

responsible for the production of the compound ammonia; which is accountable for the world’s consumption of natural gas (BBC, 2014). The Haber process is the method of synthesizing the compound of ammonia which is produced from Hydrogen (H2) and Nitrogen (N2) gas (Sinha, 2014). In 1909 a German named Fritz Haber developed the compound of ammonia, thus The “Haber” process was named after the physical chemist (AUS-e-TUTE, 2014). In 1918 Fritz Haber received the Nobel Prize for this method; in…

From Beginning to End and Back Again: An Analysis of Cycles in Bei Dao’s ‘At the Sky’s Edge’ At the end of Süskind’s Perfume, Grenouille realizes how much he actually hates people and decides to return to Paris where he allows himself to be torn to pieces and consumed by those drawn to his perfume. Grenouille was born to a fishwife that left him and many other illegitimate infants die, but unfortunately Grenouille was rescued and lived a life void of love and emotion. Grenouille turned out to…

effectiveness during regular driving. As a result, the cars emit nitrogen oxides at up to 40 times more than the allowable standard. The software enables cars to get better fuel economy at the cost of higher nitrogen oxide emissions (Boston et al., 2015). Volkswagen tried to sell their cars saying their cars had better performance and lower emissions but they did not mention the nitrogen emissions. Emission of up to 40 times more nitrogen by Volkswagen cars was a bad hit for the environment.…

Some issues regarding emissions include the Volkswagen Scandal which involved the German company activating emission controls to meet laboratory test standards with nitrogen oxides, but in real driving emit up to 40x more; test manipulation is a growing problem in the world today (EPUK 1). As a result of test manipulation, millions of vehicles on the roads in the US and all over the world are operating without properly…
