In life we heard a lot about Nitrogen Gas. It is chemical element with seven of atomic number and it is makes up about 78% of the earth's atmosphere. It included an estimated about 4,000 trillion tons of the gas. In 1772, Nitrogen had discovered by Doctor Daniel Rutherford. He called this gas "fixed air". He started his research on carbon dioxide. In 1786, Antoine Laurent de Lavoisier who was isolated nitrogen. He pointed out that this gas did not combine with any other chemical element. Also, Carl Wilhelm Scheele and Joseph Priestley were studied this gas. The last one was the chemist Jean-Antoine Chaptal in 1832 who Was suggested Latin term nitrogenium from the Greek nitro. It was appointed the N later in 19th century. Plants produce proteins composite nitrogenous easy dissolved in the soil. Some nitrogen dissolved in the soil comes from the atmosphere to form nitric acid, reacts nitrogen with oxygen in the event of lightning component of numerous compounds known as oxides of nitrogen, which in turn react with water consisting of nitric acid, which endured rain to the soil. In that case, nitrogen gas is one of important element for the organisms. It is approximately 4/5 of the earth's atmosphere.
What is nitrogen? It is having an atomic number seven. It has five electrons in the outer shell. It is non-metallic chemical element, tasteless and an odourless. Difficult soluble in water and cannot react easily with many other elements. A daily basis, most organisms consume nitrogen in their food. It makes up about 80% of the atmosphere, but oxygen gas only covering 20% of the atmosphere. It can be condensed to liquid nitrogen. The boiling point of nitrogen is at a temperature of 195.8 m and freezes at -9. 209 m....

As has been noted, nitrogen is chemical element with seven of atomic number and it is makes up about 78% of the earth's atmosphere. In 1786, Antoine Laurent de Lavoisier who was isolated nitrogen. Of course, nitrogen fertilizer is useful in farming industry. It has effective the environment such as soil, groundwater and organisms. By that, it will destroy very soon if use it so much. Also, legumes produce such as peas and soy, protein nitrogen from the air with the help of a specific type of bacteria. One of important application is use liquid to store biological substance. Actuality, nitrogen gas is necessary element for organisms. Also, it is approximately 4/5 of the earth's atmosphere. In my opinion, farmers and companies must decrease using nitrogen fertilizer and replace it by using natural fertilizer.
Chemists are the specialists in chemistry, that interact with chemical properties, and reactions. The earth is made up of different gases. Some of this gases are needed for life in the planet but other gases can be harmful to the living. Gas’s use in regular quantities are favorable to the earth. The world started to become more advance and had to use more of this gases to produce everyday objects and inventions by men. Little did we knew this chemicals we going to affect us in our life. Chemist Jose Mario Molina actually discovered that chlorofluorocarbons were affecting the ozone layer.
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.)
Currently, the United State’s Gulf of Mexico experiences an annual, seasonal “dead zone” as a result of hypoxia. Hypoxia is a low level of dissolved oxygen (<2mg/L) in an area of water. Hypoxia is typically temporary and seasonal, but the low oxygen levels can be devastating to aquatic organisms. Hypoxia occurs in many oceanic waters worldwide, but there is a growing area of concern in our Gulf of Mexico coast. Hypoxia is largely caused by nitrogen fertilizer application for agriculture, with heavy concentrations coming from the Midwestern US. Nitrogen mobilizes as nitrate, and is transported via surface water runoff. The runoff enters tile-drain supported ditches, enters streams and joins the Mississippi river, eventually reaching the gulf. Nitrate mobilization is a problem for human health, and ag. runoff is also often attributed to the contamination of surface and well-water sources in rural areas. High levels of nitrates restrict the ability of red blood cells to carry oxygen. This can harm humans, and is the major cause of infant methemoglobinemia, or “blue baby syndrome”. The safe drinking level standard is 10mg/L.
Corn helps the cows, chicken, and other animals grow faster and produce more milk, etc. as well. Instead of animals being out free in their natural environment, they are more indoors tethered to machines, eating corn. 2) All life is based on nitrogen. It forms the building blocks of organic materials and genetic information. But most of the earth's 80% nitrogen is unusable, unless it is “fixed” by combining it with hydrogen atoms. In 1909, Fritz Haber figured out how to make synthetic, usable nitrogen, which geographer Vaclav Smil calls the most important invention of the twentieth century. Without it, the human population would eventually have starved. Creating so much extra nitrogen has disrupted the natural cycle of nitrogen production. The nitrogen that isn't used by the corn evaporates into the atmosphere, which creates acid rain and speeds up global warming. The excess runoff of nitrogen-rich water makes the algae bloom in the Gulf of Mexico,
Nitrogen fertilizers: firstly nitrogen is found in the air, so air is pumped into a large vessel. The air is warmed and oxygen is removed becoming steam. This leaves hydrogen, nitrogen and carbon dioxide. To remove the carbon dioxide an electric current is introduced into the system. And finally remains ammonia. Ammonia is further processed adding air to the solution and making nitric acid. In conclusion when ammonia and nitric acid are combined is made ammonium nitrate, the component used as fertilizers.
For farmers to meet the demands of the people they must do as needed to their crops to make them fresher, brighter, and grow quicker. Fertilizer does that for the farmers as well as keep their land looking fresh and green and that helps them to reach food production needs which is a good thing. However, much is wasted and it can leave catastrophic results to our water and selves. “Rainfall and irrigation water inevitably washes the nitrogen from fields to creeks and streams, which flows into rivers, which floods into the ocean. This explains why the Mississippi River, which drains the nation’s Corn Belt, is an environment catastrophe.” (Manning, 270). The Mississippi River along with many other bodies of water are undrinkable, and highly toxic all due to man-made fertilizer. Polyface has a solution to this problem by having all their fertilizer be completely natural and organic. “the cattle and their manure are a means to an end. Or is it a system for producing grass-fed beef without the use of any chemicals, in which case the chickens, by fertilizing and sanitizing the cow pastures, compromise the means to the end.” (Pollan, 347). Polyface Farms does preciously this. It has its livestock fertilize the fields on their own and it works just as well as nitrogen fertilizer. The Polyface fields may not be as evenly fertilized as industrial fields due to where the animals choose to go
Now I?m going to give you the chemical breakdown of neon. Neon?s atomic number is #10. Neon has 10 protons, 10 neutrons, and 10 electrons. It belongs to the Noble Gas section of the periodic table. Its atomic mass is 20.1797. All the noble gases have the maximum number of electrons possible in their outer shell making them stable and un...
For years farmers have been adding natural fertilizers to their crops. It is a big risk though. Over fertilizing is very dangerous. It puts high concentrations of salt into the soil. It can also affect the water resources nearby. Nitrogen, Phosphate, and Potassium are the basics of fertilizer. If a certain nutrient is short in supply the fertilizer might not work as well. Calcium, iron, manganese are also nutrients that might be needed. So don’t just trust the fertilizer bag that says it has all the nutrients, test it out. (Miller and Levine 717)
Hydrogen is a tasteless, odorless, colorless gas. Hydrogen is found in group 1 and period 1 on the periodic table. Hydrogen is classified as a nonmetal on the periodic table. The symbol for hydrogen is represented by an H, its atomic number is 1, and its atomic weight is 1.0079. The hydrogen atom consists of one proton, which has a positive charge, and one electron, which has a negative charge. The term hydrogen comes from two Greek words meaning water-former. Henry Cavendish, an English scientist, discovered it in 1766. Named by Lavoisier, hydrogen is the most abundant of all elements in the universe. The sun and many other stars consist of mostly hydrogen. It is the third most abundant element on earth. It is estimated that hydrogen makes up more than 90% of all the atoms or three quarters of the mass of the universe. Hydrogen plays an important part in powering the universe though both the proton-proton reaction and carbon-nitrogen cycle. Hydrogen occurs in almost all organic compounds. Many of the compounds found in plant and animal tissues are organic. Production of hydrogen in the U.S. alone now amounts to about 3 billion cubic feet per year. Some of the methods that hydrogen is prepared by are steam on heated carbon, decomposition of certain hydrocarbons with heat, action of sodium or potassium hydroxide on aluminum, or displacement from acids by certain metals. Hydrogen may be condensed to a liquid that boils at -257.87°C and freezes at -259.14°C. Hydrogen ...
* Nitrogen Oxides are presented through the atmosphere. N2O are very powerful in the chemistry of the troposphere and the stratosphere, and they are very important in ozone production and in the destruction processes. There are a number of sources (the oxidation of N2O like lightning and fossil fuel combustion) whose contribution to NOx concentrations in the upper troposphere is not well measured.
Nitrogen containing flame retardants release stable and inert compounds like nitrogen gases which stop the fire cycle by either interfering with the flammable gases or with the thermal degradation of the burning material. Nitrogen containing FRs can also enhance the performance of phosphorus FRs when
In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research on "global biogeochemical cycles" as well as the effects of supersonic transport aircraft that release nitrogen oxide into the stratosphere.2 In 1974, Molina and Rowland found that human-made chlorofluorocarbons used for making foam, cleaning fluids, refrigerants, and repellents transform into ozone-depleting agents.3 Chlorofluorocarbons stay in the atmosphere for several decades due to their long tropospheric lifetimes. These compounds are carried into the stratosphere where they undergo hundreds of catalytic cycles with ozone.4 They are broken down into chlorine atoms by ultraviolet radiation.5 Chlorine acts as the catalyst for breaking down atomic oxygen and molecular ozone into two molecules of molecular oxygen.
Farmers apply nutrients such as nitrogen, phosphorus, manure, and potassium in the form of fertilizers to produce a better product for the consumers. When these sources exceed the plants needs or if these nutrients are applied before a heavy rain then the opportunity for these excess to wash into aquatic ecosystems exists.
Carbon, an element discovered before history itself, is one of the most abundant elements in the universe. It can be found in the sun, the stars, comets, and the atmospheres of most planets. There are close to ten million known carbon compounds, many thousands of which are vital to the basis of life itself (WWW 1).
