    Nitrogen is a colorless, odorless gas that can be found in group 15 of the periodic table. Nitrogen is represented by the symbol, N, and has an atomic number of 7. This element was discovered by Daniel Rutherford in 1772. Mr. Rutherford studied Edinburgh University where he began his research on this gas. It started with an experiment including a mouse in a small enclosed area, and from there concluded that the air being released by the mouse was what we know as Nitrogen. At room temperature this

    more convenient than the old-fashioned jars of liquid polish or cans of powdered cleanser, which can spill or be applied too thickly.  At the same time, however, most of us probably do not know how the aerosol can works.  We accept its ease and convenience without realizing that the aerosol can is quite a complex container. An aerosol is not a simple cleaner or polish; it is a colloidal system.  That means it consists of finely divided liquid or solid particles, called a product, dispersed

    elements to help them grow. Plants make carbohydrates. A plant needs nitrogen, phosphorus, potassium, calcium, sulfur, and magnesium the most to grow healthy. Most soils naturally contain enough trace elements for field crops, but such elements must be added when certain fruits and vegetable plants are grown. Nitrogen, phosphorus, and potassium are the top three elements needed in plant growth. Legumes are plants which absorb nitrogen gas from the air and bring the gas to the ground. Legumes are planted

  • Essay On The Haber Process

    Parker Bell Mrs. West Chemistry, P.2 23 February 2014 The Haber Process The Haber process, otherwise known as the Haber-Bosch process is the reaction of Nitrogen (g) and Hydrogen (g), to produce ammonia; a huge part in the making of plant fertilizers. Ammonia is extremely difficult to produce on a large industrial scale, but the fertilizer made from it is responsible for sustaining one-third of Earth’s population. It was created by a chemist by the name of Fritz Haber, and it was then asked for another

    occurred, there was 0.46 grams of elemental copper metal. After the copper was added to the 250 milliliter beaker containing the 5.0 milliliters of nitric acid, nitrogen dioxide gas came out. The gas color was a light brown color, and the clear nitric acid within the beaker became a green-brown color. Once the chemical reaction concluded and nitrogen dioxide gas stopped releasing from the beaker, 20 milliliters of distilled water was added to the solution, and the color within the beaker turned to a neon

    compounds quite unstable. Molecules of compounds with neon, another noble gas, and with hydrogen have been detected. Helium is the most difficult of all gases to liquefy and is impossible to solidify at atmospheric pressure. These properties make liquid helium extremely useful as a refrigerant and for experimental work in producing and measuring temperatures close to absolute zero. L...

  • Nitrogen, Carbon and Phosphorus Cycles

    865 Words  | 2 Pages

    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

  • Nitrogen Management

    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

    but it is currently a hot topic for the agriculture industry. Presently, there are about 20 million pigs being raised in Iowa alone, and Iowa’s lush cropland greatly benefits from the manure output. Manure provides the soil with nutrients such as nitrogen, phosphorus, and potassium; improves suitability for planting; increases water holding capacity; reduces erosion; and supplies an energy source for microbial activity (Murphy, 1996). Although the soil quality is improved, there are some concerns

    balloons. It is also an inert shield for arc welding, to pressurize the fuel tanks of liquid fueled rockets and in supersonic wind tunnels. Helium is also used in technology such as, computer chip manufacture, cell phones, fiber optic cables, MRI machines, and laser production. When you combine helium with oxygen you create nitrogen free atmosphere for deep sea divers so they can avoid a condition called nitrogen narcosis. Helium is said to be the second most abundant element. Unfortunately, most

    of a catalyst, a reaction occurs which converts the ammonia to nitric oxide. The nitric oxide is further reacted in the presence of water to produce nitric acid. Nitric acid and ammonia are used to make ammonium nitrate. Its high concentration of nitrogen makes this material a good fertilizer component. Finally, it can then be stored until it is ready to be granulated and blended with the other fertilizer components. Phosphorous fertilizer component Phosphorus is treated with sulfuric acid to isolate

  • Solids, Liquids, and Gases

    Solids, liquids, and gases are the three main, or fundamental phases of matter. Each one has a different density and a different level of stability. What determines the stability of each phase is the bond between it's atoms. The tighter the bond between it's atoms the more stable that phase of matter is. Solids are the most stable form of matter, followed by liquids, and then gases. Solids have a definite shape and do not take the shape of their container. Liquids do not have any definite shape and

According to all four references, the single component affecting the grass is Nitrogen (N2). Dogs are carnivores and therefore require a protein rich diet. Nitrogen is the fundamental breakdown product of protein. The excess amount of nitrogen is excreted through the dog’s kidneys ending up as urine. The concentrated liquid nitrogen in dog
