Nitrogen

Why is ammonia important? The primary use of ammonia (NH3) is to provide nitrogen atoms for plants so they are able to make amino acids, proteins, and other biologically important molecules. In order to provide the vast amount of food demanded by a growing industrialised population, more efficient agricultural techniques and larger scale farms must be employed. There exists some naturally occurring nitrogen fixing bacteria that are able to convert atmospheric N2 into the more useful form of NH3…

effluent, or out-flowing, water is pumped out to Beaver Run, which then feeds into Tinker’s Creek, which then empties out into the Cuyahoga River, which goes to Lake Erie. The remaining amount of B.O.D. is .61 ppm. The remaining amount of Ammonia (Nitrogen) left is .07 ppm, a drastic decrease. The amount of phosphorous left was .49 ppm. Trace amounts of mercury, copper, and lead are still left, but not enough to harm…

Combustion happens when a fuel reacts with oxygen. Depending on how much oxygen is available, fuels can combust completely or incompletely. Complete combustion happens when there is excess oxygen available to the fuel. Complete combustion of hydrocarbons produces water (H2O) and carbon dioxide (CO2). Incomplete combustion happens when there is limited oxygen. The incomplete combustion of hydrocarbons produces water (H2O), small amounts of Carbon Dioxide (CO2), Carbon Monoxide (CO) and…

strongly recommend soil test prior to the fertilizer and lime application. Finally explain the correct ration of NPK should be in the fertilizer mixture. Fertilizer bag illustration tell to the reader how to recognize the NPK level easily. (NPK = Nitrogen, Phosphorus and Potassium) Fertilizing lawns - Summery This bulleting is web based but printer friendly version is available. The article can be emailed easily. Not available in PDF…

previous two years have resulted in 0mg/L of nitrates occurring in the water. From a chemical standpoint, this means that the water quality is outstanding. However from a creek and biological quality standpoint, it is not healthy as plants consume nitrogen, and reproduce…

Phlogiston theory The phlogiston theory states that the every combustible substance on this planet contains phlogiston. When a combustible substance is burned, phlogiston is released into the air. The people behind the phlogiston theory believed that the whenever a substance sets on fire, the fire gives off phlogiston. The phlogiston was believed be the kind of gas which causes fire. Without phlogiston, the combustible substance won’t be able to set on fire. In the late 1660’s a scientist…

problem that led to the use of this chemical was the increasing population and larger demand for food which meant farmers needed to grow higher yield crops at a faster rate. Fertilizers were heavily used to provide nutrients with ingredients such as nitrogen, phosphorus, potassium, which are essential chemical elements for plant growth and increases growth rate and photosynthesis…

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…

to all lakes over time as the weathering of rocks and soils from the surrounding area that leads to an accumulation of nutrients in the water. It can also be caused by run-offs of fertilisers. Three of the key components of modern fertilisers are nitrogen, phosphorous and potassium. After a rainy season these nutrients that were not absorbed, run off into waterways such as dams, lakes, rivers, streams, ponds and even sometimes swimming pools. The fertiliser triggers the growth of plants that are…

The FTIR spectra of four phosphazenium salts and P5+ are shown in Figure S1. Four phosphazenium salts have characteristic absorptions at 2850 and 2930 cm-1, belonging to the stretching vibration of -CH2- and -CH-, respectively, and this peak in the P5+ represents the absorption of –CH3. All the five compounds exhibit absorption at 960, 1230, and 1442 cm-1 corresponding to the stretching vibrations of P–N. In the FTIR spectrum of Cy4P1+BF4-, the peaks at 1633 and 3432 cm-1 belong to water because…
