placing it within a test tube, then adding 1mL of 6 M HCl and 1mL of BaCl2 and stirring with a glass rod for 10 seconds to observe the formation of a precipitate. Following the Anion Tests are the Cation Tests in which we find the flame test and the ammonium test. For the flame test, a nichrome wire is cleaned by dipping it into HNO3 and burning it on a Bunsen burner until the resulting flame is colorless. After the wire has been cleaned, a small portion of the unknown compound is placed on the…
this element and its significance. Nitrogenous compounds are present in all living things and fossil fuels. However, it took years for humanity to discover the element. Nitrogen had been manufactured in the days of Ancient Egypt in the form of ammonium chloride, (NH4Cl) or sal ammonia as it was known to alchemists,…
people to join his cause in the fight against the government (Etter, 2008, pp. 60-61). Etter (2008) has stated from the general basis in Turner Diaries, “a race war is ignited by the bombing of a federal building using a truck bomb made with ammonium nitrates and diesel fuel” (pp. 65). Thus, the Turner Diaries was being highly recommended by most extremist groups at the time including the National Alliance and its’ founder, William Pierce, who not only wrote the document, he also used a false…
of denitrification also tend to be higher (Gilbert et al., 1995, Ieno et al., 2006) as bioturbation promotes coupled nitrification-denitrification (Kristensen and Blackburn, 1987, Dollhopf et al., 2005). The higher nitrification activity increases nitrate production to fuel denitrification, while burrows increase the oxic-anoxic sediment interface to bring the processes into closer proximity. Also, oscillating oxic and anoxic…
truck bomb with some of his own variances applied to it. Although, some of the ingredients were difficult to get. McVeigh and Nichols would make calls around the country until they could purchase what they needed. He used tovex sausages, and ammonium nitrate fertilizer, blasting caps, and nitromethane racing fuel in order to make the bomb more potent so it would cause more damage (PBS). Then after building the bomb at a nearby lake with the help of Nichols. McVeigh would drive the Ryder…
Identifying a bacteria based off of physical characteristics is almost impossible due to the commonality of shapes and physical features. Because of this, a wide range of biochemical tests were preformed in order to better identify the bacteria. Being able to identify an unknown was the most interesting part of the microbiology lab this semester, as well as, being able to preform the various tests. Proper aseptic technique was used throughout the semester and followed during all biochemical…
In the entire world, food stands as a significant reason behind the considerable number of diseases. Bangladesh is not all an exception in this case being the third world developing country in South Asia. For the last couple of decades the most serious threat to public health in Bangladesh is the consumption of unsafe food. In an ethical manner doing business in today’s world is very rare. The food and beverages industry entirely corporations are involved in handling uncooked food stuff…
in this essay. IEDs are made by terrorists in old, abandoned buildings using special chemicals. According to Time Magazine’s article Afghanistan’s IED Complex: Inside the Taliban Bomb Making Industry, IEDs are being made using CAN or Calcium Ammonium Nitrate. When this chemical is mixed with potassium chlorate a chemical reaction…
Water is a colorless, transparent and odorless liquid that exists in all three states of matter. It plays three major roles as the: a) universal solvent, b) reactant molecule, and d) temperature stabilizer. Water is created when Hydrogen and Oxygen undergoes synthesis reaction as 2H2 + O2 2H¬2¬O. In the process, an oxygen atom is covalently bonded to the two hydrogen atoms forming a non-linear molecular shape of water. According to the Valence shell electron pair repulsion (VSEPR) theory, the…
produces a carbon dioxide gas, as well as water and salt. Similarly, when a metal sulfite and an acid are mixed, it produces water, salt, and a sulfur dioxide gas, as opposed to carbon dioxide. Both a metal sulfide and acid-base reaction, and an ammonium salt and strong base reaction, produce a hydrogen sulfide gas and a salt. (LHS AP Chemistry,…
