1. Describe the principal organs responsible for producing ammonia and how ammonia is produced. The major sites for the production of ammonia are the intestines, liver, and kidneys. It is biosynthesized through normal amino acid metabolism. The kidneys generate ammonia from glutamine by the actions of renal glutaminase and glutamate dehydrogenase. Ammonia is formed from urea by the action of bacterial urease in the lumen of the intestine, which is absorbed from the intestine by the portal vein. Amines
The nitrogen in ammonia makes many people think that it can double as fertilizer and promote plant growth. However, using household ammonia, which is present in many cleansers, can do more harm than good. Learning the ins and outs of this chemical and its effect on plant growth might make you think twice about using it. Ammonia and Plants Ammonia is presents in soil, water and air, and is an important source of nitrogen to plants. Nitrogen promotes plant growth and improves fruits and seed production
Fertilizer Company; which is owned by Adair Grain Inc. which had stockpiles of anhydrous ammonia and ammonium nitrate amongst other agricultural items; was the center and cause of the blast. It is not the first time that an explosion such as this has happened in the state of Texas; in 1947 in Texas city, Texas an explosion that caused nearly 600 deaths had ammonia as a key part in the blast (Jonsson, 2013). Anhydrous ammonia is stored as a liquid in pressurized tanks and after it has been sold to local farmers
In the history of chemistry, there was a chemist who left the world with intense debate about his the merits and demerits. He is the world-famous German physical chemist, inventor of ammonia Fritz Haber. The people who praised Haber say he was an angel, bring joy and harvest to mankind. The people whom cursed him say that he is a devil, a disaster for humanity, suffering and death. Haber was born in Silesia Breslau (now Wroclaw, Poland) on December 9, 1868, his father was a knowledgeable and good
Detection of ammonia can be done using gas sensors. Examples of different application areas of ammonia gas sensing are; environmental monitoring, medical diagnostics, chemical laboratories and detection of ammonia in portable water and wastewater (Timmer et al., 2005). High concentrations of ammonia are easy to detect while for very low concentrations we require different gas sensors operating at different sensing principles. Ammonia gas sensors operate at different temperatures each having a specific
Ammonia (NH3) is a very imperative substance or product that is used day to day in everyone’s lives. Ammonia (NH3) is used to produce fertilizers, household cleaning products and is the starting material for many explosives and many pharmaceutical products. Ammonia (NH3) is also used to create nitric acid (HNO3), also a very crucial substance used in our daily lives. The Haber process is the industrial process for the manufacture of ammonia (NH3) from hydrogen (H2) and nitrogen (N2), if not for the
but this functioning resorts in waste products which are often useless and harmful. It is therefore important that the body removes these products to prevent harm. Tomar (2009, p. 40) suggests that the most common waste products are carbon dioxide, ammonia, uric acid, urea, creatinine, amino acids, various pigments and inorganic salts. In multicellular organisms, organs have evolved in order to deal with the waste products produced and enable them to be excreted from the body. In humans, these organs
century the world-wide demand for ammonia for use in fertilisers (in the form of nitrates) and in the production of explosives for use in mining and warfare could only be satisfied on a large scale from deposits of guano in Chile (2). Though this deposit was of huge size (approximately five feet thick and 385 kilometres long) it represented a rapidly depleting resource when compared to world-wide demand. As a result of this there was much research into how ammonia could be produced from atmospheric
using a silver nitrate solution combined with the synthesized cobalt compound. The solution filtered in the crucibles is then dried in the oven until a constant weight was found. % NH3 was found by gathering ammonia from cobalt compound solution into a boric acid solution. The boric acid ammonia solution is then titrated using standardized HCl. % CO was found using spectroscopy. The cobalt compound falls under the category of chemistry called coordination chemistry, which is the interaction between

Vertebrate Adaptions For Terrestrial Life AP-Biology Essay on vertebrate structural adaptations for terrestrial life. The problems of survival of animals on land are very different from those of survival of animals in aquatic environment. Describe four problems associated with animal survival in terrestrial environments but not in aquatic environments. For each problem, explain a physiological of structural solution. Four problems faced by animals on land are breathing (respiration),
and non-biological (lightning, combustion and volcanism) systems, or man-made processes (mainly industrial ammonia production)” (p. 1). There are four processes in the nitrogen cycle, namely nitrogen fixation, decomposition, nitrification, and lastly, denitrification (refer to Figure 1 in Appendix 1). Firstly, the cycle involves nitrogen fixation. Nitrogen fixation is a process of forming ammonia (NH3) or nitrate (NO3-) from inorganic nitrogen in the atmosphere. Organisms are not able to consume the
In 1868, on December 9th in Breslau, Prussia (now Wroclaw, Poland), Fritz Haber was born to a prosperous Jewish chemical merchant. He studied at St. Elizabeth Classical School and took an early interest in chemistry, performing various experiments during his time there (Fritz Haber - Nobel Prize Biographical). Afterward, he studied at the Universities of Berlin, Heidelberg, and Zurich before working for his father for a short while (Fritz Haber - Facts and Biography). Young and ambitious
of nitrogenous waste. Nitrogenous waste is ammonia, urea and uric acid. In the human body only ammonia and urea are produced and the liver quickly changes the harmful ammonia into the tolerable urea for excretion from the body. Ammonia is toxic to humans in high concentrations (see Table 1). Ammonia is the by-product of protein being broken down. Ammonia is formed by the breakdown of amino acids taken from excess proteins. The liver converts the ammonia into urea, which is then removed from the
grade meat mixed with cartilage, connective tissue, and anything else that is left then gets heated up to a point where the lean beef is separated from the fat. After separation, the meat is then treated with ammonia to get rid of bacteria like salmonella and E. coli. After contact of the ammonia with the water within the beef it creates ammonium hydroxide, the meat then is finely ground, cut into pellets or block, then flash frozen and shipped out to be used as an additive in the pure beef and now
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
the fish excrete ammonia (~90%) and urea (~10%) (Timmons and Ebeling, 2013). The biogeochemical nitrogen cycle is driven by microorganisms, that perform nitrification, anaerobic ammonia oxidation. Nitrification leads to the production of nitrite and nitrate from the oxidation of ammonia. Ammonia and nitrite are inherently toxic to fish; however, the sensitivity to these nitrogenous compounds varies by species. It was suggested that in Cyprinus carpio, or common catfish, ammonia is regulated at the
and was first synthesized by a German scientist Friedrich Wohler in 1828 through a mistake when he was actually trying to synthesize ammonium cyanate (Arthur Greenberg, 2007). In the presence of hydrated air, urea has the characteristic smell of ammonia and is odourless in the presence of dry air (NCBI, n.d.). The chemical and physical properties of urea were summarized in Table 1.1 (National Library of Medicine, n.d.) Figure 1.1: Two-Dimensional Structure of Urea (NCBI, n.d.) Table 1.1: Chemical
1. Definition of Acid and Bases: 1.1 Arrhenius definition of acid and base: Arrhenius Acid: The substance or a compound which gives H+ ions in aqueous solution Arrhenius base: Base is a substance or compound that produces OH- ions in aqueous solutions. Chemists have known for some time that the H+ ion doesn’t exist in aqueous solutions as an independent species. The modernized Arrhenius definition of acid is that they are substances that produce H3O+ ions in aqueous solutions. It did not take longer
tube for further analysis. One unexpected result was that a white solid precipitate remained at the bottom of the tube. This was unexpected since if there were silver in the solution, it would have dissolved into Ag(NH3)2+(aq) after addition of ammonia. The mystery precipitate could have been either unreacted AgCl (s), PbCl2(s) that did not dissolve in the first separation step, or a newly formed compound. In order to determine this, the supernatant underwent the final identification
