Nitrogen is one the most inert chemicals after the noble gases, which makes it a great environment for the performance of limited chemical reactions.8,9,14,15 There is no surprise that nitrogen is a great choice because of its high dissociation energy, high ionization energy, and the inability to access its highest vacant molecular orbitals.15 Molecular dinitrogen is a tightly wound nonpolar molecule in character with σ and π electrons.14 The inertness of molecular dinitrogen makes practicable activation a challenge for chemists, but nature can do this process easily.10,14 Nitrogen is not only an important element in the area scientific research, but biological processes also have a much desired need and use for nitrogen.15
Biological systems use nitrogen for their own life support processes and because nitrogen is the controlling factor in protein synthesis. Reduced nitrogen in the biosphere is required in order to perform the needed protein synthesis.8,9,15 The term of nitrogen fixation is no longer solely limited to biological systems and can now be defined more generally as the reduction of molecular dinitrogen to ammonia.15 Nitrogen fixation in organisms began to appear late in evolutionary development because it was thought that the earth had possessed ammonia as a main aspect and component in the atmosphere.1,15 Once the natural occurring supply had diminished and sufficient nitrogen appeared, the systems were required to evolve and adapt in order to continue getting the needed ammonia for survival.1,8,9,15 Reduction of dinitrogen is a key reaction in nature because nitrogen is an important element, but molecular dinitrogen alone is in an inaccessible form for most living organisms to use practically.11 Nitrog...

Catalysts Essay - Catalysts speed up the rate of reaction and remain chemically unchanged or being used up in the process, and are widely used in industry. Enzymes are biological catalysts made up of proteins, and can be used a lot in industry since they operate best close to room temperature and pressure which can be maintained in industrial processes. Catalysts will speed up rate of reaction and can also be used to change properties of a product to increase it’s usefulness – it can turn light, bendy poly(ethene) into a more dense and less flexible material with a higher melting point....   [tags: Chemistry ]

Nitrogen as a Fertilizer, Nutrient, or Pollutant Essay - Nitrogen as a Fertilizer, Nutrient, or Pollutant Nitrogen can always be a fertilizer, nutrient, or pollutant depending on the circumstances and the environment it is in. As a fertilizer, nitrogen can be extremely useful in aiding the growth of many plants. As a nutrient, nitrogen is essential to many plants growth and survival. As a pollutant, nitrogen can not only affect the plant at the given time but be very detrimental many years down the road. No matter where you go nitrogen will always be either a fertilizer, nutrient, or pollutant....   [tags: Nitrogen Biology Environment Essays Papers]

Nitrogen Essay - Nitrogen Nitrogen, symbol N, gaseous element that makes up the largest portion of the earth's atmosphere. The atomic number of nitrogen is 7. Nitrogen is in group 15 (or Va) of the periodic table. Nitrogen was discovered by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist, Antoine Laurent Lavoiser about 1776. Nitrogen is a colorless, odorless tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can be compressed into a colorless, crystalline solid....   [tags: Papers] 486 words

Catalysts and Chemical Reaction Essay - CATALYSTS Catalysts are substances used to increase or decrease the rate of a chemical reaction. A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction.The word catalysts originally comes from the word Catalysis meaning the change in rate of a chemical reaction. Catalysts unlike other substances, may participate in many chemical transformations but never consumed by the reaction itself. This means that, when a catalyst is added to two substances to increase the reaction rate between them, the catalyst isn't consumed and may be used again.([3]" Reactions: Catalysts and Inhibitors.") For example, the decompos...   [tags: Definition, Function, Environmental Effects]

Catalysts Used in Cracking Essay - A catalyst is a substance that increases the rate of a chemical reaction. It does not change the equilibrium but instead provides a different pathway. Catalysts usually lower the activation energy. For the cracking process, most of the people in this production utilize alumina (aluminum oxide, AL203) as a catalyst. It functions by decreasing the energy essential to reduce C-C bonds when the larger hydrocarbon molecules are absorbed on the outside of the alumina particles. Catalytic cracking breaks down complex hydrocarbons into simpler molecules in order to boost the quality and quantity of lighter, more desirable products and lessen the amount of residuals....   [tags: Thermal, Molecules, Process] 874 words

The Significance of the Nitrogen Cycle in Ecosystems Essay - The Significance of the Nitrogen Cycle in Ecosystems Nitrogen makes up about 80 per cent of the Earth's atmosphere as a gas. However the gaseous molecule is very stable and has to be transformed before it can be used by most organisms as it is only available to them when it is ammonium or nitrate. It can only be removed from the atmosphere in two ways: by lightning and by nitrogen fixation. Only a few species can convert nitrogen by nitrogen fixation to biologically useful forms....   [tags: Papers] 968 words

Nitrogen, Carbon and Phosphorus Cycles Essay - Nitrogen, Carbon and Phosphorus Cycles The carbon cycle deals with the interaction of carbon between living organisms and the nonliving environment. This cycle is a process through which all carbon rotates. The main result of the carbon cycle is to serve as a great natural "recycler" of carbon atoms. The cycle works in a very basic way. First, carbon is taken from carbon dioxide found in the air. Plants take in carbon dioxide from the atmosphere. Plants absorb carbon dioxide from the atmosphere and use it, combined with water they get from the soil, to make substances they need for growth....   [tags: Papers] 865 words

How Natural Processes Operate at Coastal Geographic Environment Essay - How Natural Processes Operate at Coastal Geographic Environment Natural Processes are actions or events that have natural causes, which result in natural events. The three main coastal environment processes that operate at Muriwai are Coastal Erosion, Coastal Transportation and Coastal Deposition. The elements that interact to produce natural processes are wind, waves and tides. Each phenomenon at Muriwai's coastal geographic environment has been produced by interaction. Coastal Erosion is a process at Muriwai that gradually wears away the rock particles of the earth's surface, transporting them to another location....   [tags: Natural Processes Environmental Essays] 1040 words

Nitrogen Management Essay - Nitrogen management is crucial component for sustainable crop production, it is desirable to adapt N supply with crop N use to maximize efficiency. In Egypt, due to intensive cultivation of high yielding crop varieties, the nutrients supplying capacity of soil is declining. Producers tend to apply insurance application of N to make them feel more confident about N sufficiency. These practices may lead to over application of N fertilizer and result in groundwater pollution by nitrate (NO3) due to the elevated levels of NO3 in the soil profile (Asadi et al....   [tags: Environment, Agriculture, Crop Production] 629 words
