...Nitrogen Introduction and Properties of Nitrogen Nitrogen is a non-metallic, p-block element from group 15-period 2 of the periodic table of the element. In 1772, a Scottish physician and chemist Daniel Rutherford (1749-1819) performed an experiment that leads to discovery of nitrogen. He places a bottle that is turned upside down in a water bath so as to trap some air. A burning candle was placed inside the bottle that reacts with oxygen. Rutherford concluded that the remaining gas was nitrogen. Nitrogen comes from nitro and gen that means niter-forming. Nitrogen is the most abundant gaseous component of earth’s atmosphere constituting 78% by volume.It is colorless, odorless... and commonly...

The carbon atoms that exist in peoples’ bodies today have been used in numerous other molecules for as long as the atoms have been in existence. Since all living things are made of carbon, the carbon cycle is essential to life. Plants obtain carbon atoms and other important elements from the atmosphere through the process known as photosynthesis. The carbon-engorged plants are consumed by animals that eat plants, thus obtaining carbon atoms for themselves. When the animals and plants die and they decompose... ? Carbon, Phosphorus, and...

...Nitrogen and Phosphorus represent two major elements that are essential in the growth of organisms. Nitrogen is used by organisms to make protein and nucleic acids. Plants also use it in the process of photosynthesis while phosphorus forms a massive component of nucleic acid and is used by animals to make shells, bones, and teeth. Despite their significant input into the growth of organisms, too much of Nitrogen and Phosphorus presents a threat to the marine environment as it leads to the formation of dead zones. Dead zones represent low-oxygen areas (hypoxic areas) in the world’s coastline and lakes. All organisms need... Gulf Of Mexico Dead Zone All organisms require nutrients in order to grow....

...Nitrogen Oxides, but Nitrogen gas, carbon dioxide, and water vapor are the main ones. Carbon Monoxide, other hydrocarbons, and Nitrogen Oxides are responsible for the pollution caused by cars, since Carbon monoxide is poisonous and can kill if it is inhaled in large amounts. Hydrocarbons result from incomplete combustion of fuel and when released into the air they form smog, which is a form of air pollution. Nitrogen oxides cause acidic rain when released... through the honeycomb, which is coated with the catalysts platinum and rhodium. At this stage, the exhaust gases that are converted to less harmful gases are the nitrogen compounds, which are broken down into...

...Nitrogen (N), phosphorus (P) and Potassium (K) are also present in the soil. Appropriate and balanced composition of these minerals defines soil fertility. Too high concentration of nitrogen retards the growth, while high concentration of phosphorus is responsible for reduced water absorption. High bulk of phosphate is responsible for binding with zinc and also hinder sulfur availability. High load of potassium curtails the availability... Soil is the most imperative part of the natural milieu. Life is impossible without soil as it holds biotic as well as abiotic components such as rivers, landforms and rocks. The nature of soil vary from place to place and hence it decides the distribution and range of ...

...nitrogen fertilizer was observed on the yield of maize crop. This yield was measured in milligrams of dry mass harvested in 100 acres for a period of a year. The process... Variability in Maize Yields and Properties of soil in Arable and non arable soils. Introduction. Soil variability can be defined as the observed variability on a considerable distance between units that are distinctly different like land facets and parent materials. Considering the previously done research, there has been very little attention that has been given towards the component micro variability that pertains the recurrent and local variations on a single field (Ogunkunle, 2006). Prior research has reported that the influence...

...nitrogen emission, byproduct utilization, carbon dioxide capture, and improved efficiency (Leonard, 2008). Clean coal technology has not yet resulted in what would be termed as clean energy because it still releases carbon dioxide among other harmful particulate matter into the environment. Like of other fossil fuels such as diesel, coal releases sulfur and nitrogen gases as well as release of chemicals such mercury during its mining into the environment (Leonard, 2008). Such chemicals have negative pollute the environment leading to detrimental effect on the living things. However, biodiesel produced from biological waste has limited negative impact on the environment because... Clean Energy Clean...
