Ammonia

Tommy seeks for the new parts of Five Oaks because the same sights he lives with are no longer amusing. “I knew every barn, every broken windmill, every fence, every anhydrous ammonia tank, by heart.”(pg.63 l.608-609). Tommy memorized all the details in Five Oaks and searches for unique sights to take him away. Miss Ferenczi is new to Five Oaks, and she makes Tommy’s heart pound. This shows that Tommy truly has the urge to find…

and safe because they use ammonia to kill bacteria on the meat. However, ammonia hydroxide is a chemical and that chemical is put on food that will eventually be consumed. “When ammonia enters the body as a result of breathing, swallowing or skin contact, it reacts with water to produce ammonium hydroxide. This chemical is very corrosive and damages cells in the body on contact” (Department of Health.). This quote proves that it is unsafe for the workers to work with ammonia and for the…

Discussion of Results and Scientific Explanation To achieve the goal of determining an unknown acid or base, anion and cation test were performed. These tests allowed for the components of the solutions to be identified, therefore, achieve the second goal. The pH was also used in to help find the identity of the unknown solutions and it was used to draw conclusions about the solutions. Dilutions were used to help understand the different behaviors of different concentrations. Household items…

in order to learn about the Hantzsch 1,4-Dihydropyridine synthesis mechanism. Furthermore, this lab will give students a better understanding of the terms pharmacophore and a privileged structure. In order for this reaction to occur an aldehyde, ammonia, and two equivalents of a B-ketoester go through a one-pot cyclocondensation reaction. After 1,4-dihydropyridine is formed, it is then oxidized to form its pyridine derivative. Alcohol or Acetic acid is then used as a refluxing solvent for this…

Experimental: Materials – double salt (self-made & EIU Chemistry Stockroom), 6 M HCl (EIU Chemistry Stockroom), 10% BaCl2, 6 M HNO3 (EIU Chemistry Stockroom) Equipment – Ocean Optics Spectrometer USB4000, Logger Pro Procedure – In order to find the mass percent of the sulfate, the sulfate needed to separate itself from the rest of the double salt. To do this, experimenters began by weighing out 0.998 g of the double salt into a 250-mL beaker. They then used the graduated cylinder to add about…

The D-glucose serves to reduce the silver from Ag1- to Ag1+. The sodium citrate first reduces Ag1+ to Ag, and then functions to bind with the particle surface of silver nitrate particles to allow them to interact. Finally, silver nitrate can aggregate. The silver nitrate combined with D-glucose, sodium citrate, and heat forms an aggregate. The citrate binds with the particle coating and dispels the repulsion between silver nitrate nanoparticles. The nanoparticles then form an aggregate-- a loose…

Acid forming elements are chlorine, phosphorus, and sulfur (different from alkaline-forming elements). These elements are the primary element in foods containing moderate to large amounts of protein (except for milk and a few other dairy products). I decided on using peanut oil because peanuts yield an acid, thus they contain acid-ash. Acid-ash residue is inorganic radicals that form acid ions in the body, causing lower pH making the urine more acidic. Acid urine favors the excretion of kidney…

Ammonia is a compound composed of nitrogen and hydrogen, having the formula NH3. The ammonia molecule is formed by sp3 orbitals as it has a tetrahedral geometry and a trigonal pyramidal shape. Ammonia has an experimentally determined bond angle of 106.7°, and an a bond length of 101.7 pm. The nitrogen atom in the molecule has a lone electron pair, which gives the molecule a dipole moment and polarity. Ammonia’s lone electron pair makes NH3 a base, a proton acceptor, and gives it the ability to…

Ammonia is a colorless gas with a characteristic irritating odor. As we may know, ammonia is mostly used by agriculture as a fertilizer. Ammonia has not only been used as a fertilizer, but it has also been used to create explosives and even for illicit purposes. For example, ammonia is used as a key ingredient in the making of methamphetamine. Now, on April 19, 1995 a domestic terrorist attack place against the Oklahoma federal building. Ammonia was a key component used to create the high…

A. Questions A1. Suggest a reason why the electrical conductivity of tap water and deionized water might be different. Tap water is not purified therefore it contains some ions which will increase the electrical conductivity, whereas the deionized water does not contain ions so it is a very poor conductor of electricity. A2. Was there a difference in the conductivity of solid NaCl and of the 0.1 M NaCl solution and if yes, why? Yes, there was a difference in the conductivity of solid NaCl…
