Ammonium nitrate

bombing, it happened at the Alfred P. Murrah Federal Building. In this attack there was a total of 168 deaths, 19 were children that were in the day-care center that the building had, and more than 500 people were injured. The bomb was made with ammonium nitrate and fuel oil. This was the worst terrorist attack on U.S. soil until September 11, 2001. When the bombing happened it affected other buildings around. The explosion destroyed more than 300 other buildings around the immediate area. The…

Biochemical Unknown I. Introduction Cultural Characteristics or morphology and biochemical tests can be used to identify and classify microorganism. By culturing microorganism in nutrient broth, slants, and on nutrient agar plates, the cultural characteristics or morphology can be determined. In this lab, the test tube 2 was incubated in a nutrient broth. The pigmentation of the tube was yellow. The media for test tube 2 was turbid. There were a few sediment on the bottom of the broth. In…

Competition is a prevalent factor in biology that plays an integral role in the diversity of a biomes community and natural selection for species. Plants are among the most diverse groups of organisms and it all started 475 Ma ago, when spore-producing plants were the first to emerge from the sea to begin the colonization of terrestrial ecosystems. Ever since late Silurian (425 Ma), land plants have been competing, evolving and diverging to give rise to new species, while nearly all plant…

Materials Silica sol (Ludox HS-40, SiO2 40% and H2O 60%) and ammonium chloride (NH4Cl 99.99% in purity) were used as received from Sigma-Aldrich. Sodium hydroxide pellets (NaOH 99% and H2O 1%), Ammonium hydroxide, (NH4OH, 25%) and EDTA (> 99.4% in purity) were used as received from Merck KGaA. Sodium aluminate (Na2O 41%, Al2O3 53% and H2O 6%) was used as received from VWR Co. Tetramethylammonium…

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…

This experiment was designed to test what the limiting nutrient was in Loughberry Lake, as well as examine the trophic state of the lake. In order to find out what the limiting nutrient was, we performed a few different tests. We began with a secchi disk test to see the transparency of the water. Then, we took water samples that we later used to test the turbidity levels of the water after adding varying amounts of phosphorous and nitrogen. Phosphorous was the limiting nutrient in the lake,…

This lab was conducted to find the key differences between the quantity of heat (q) and ∆H of a substance. Different masses of substances CaCl2 and NH4NO3 were dissolved in water to see how changing mass impacts the q and ∆H of a substance. When the two substances dissolve, they become ions. CaCl2 dissolves in a reaction of: CaCl2 Ca2+aq + 2Cl1-aq while NH4NO3 dissolve in a reaction of: NH4NO3 NH41+aq + NO31-aq . As shown in these reactions, when ionic compounds dissolve in water, they break…

The Alfred P. Murrah Federal Building was a building for the United States Government owned by the United States Government. The building was located at 200 N.W. 5th Street in Downtown Oklahoma City, Oklahoma, United States. The Alfred P. Murrah Federal Building was designed by an architect named Wendell Locke, Locke worked for Locke, Wright and Associates. The building was built using reinforced concrete and was built in 1977. The cost of the whole building process was fourteen and half million…

Carbonyl compounds are the compounds the contain C=O group which is called carbonyl group (double bond oxygen to a carbon). There are many types of carbonyl compounds such as aldehydes, ketones, carboxylic acids, esters, amides etc. Aldehydes and ketones are the oxidation products of alcohols. Depending on the alcohol’s structure, the product obtained will be different. Primary alcohols have one carbon and two hydrogen atoms attached will produce aldehyde and then to carboxylic acid in two…

Timothy McVeigh was” born on April 23, 1968 in Lockport, New York and grew up nearby in the working-class town of Pendleton” (McVeigh, 2017).Timothy parents divorced, and he went to live with his’s father, where he started to take interest in guns. He learned to use a gun through his’s grandfather giving him target lessons. “McVeigh was also bullied as a teenager, he was also very bright, earning a partial college scholarship after graduating from high school in 1986” (McVeigh, 2017).McVeigh…
