Nicolle Bernard has been serving our country for nine years in the Air Force. Captain Bernard grew up in Madison, New Jersey and is currently stationed in Germany near the Ramstein Air Base. Nicolle is a strong woman who puts a lot on the line for our country. At age fifteen Nicolle became interested in meteorology when starting her college search. Captain Bernard needed a way to pay for college, so when she discovered the Air Force she thought this was a perfect opportunity. She received…
researched is a government job for the United States Air Force. This job involves you being in a group called a unit and there are many units at the base. The unit I will be talking about is called COMM. COMM stands for one word and that is communications. I have choose this topic for my research paper because my family has been through this branch of the military for now two generations now and I have always wanted to go through and be in the Air Force and would make my grandfather very proud…
the endpoint of a solution. It also allows us to see a physical change, thus resulting in a more accurate measure of how much was titrated. Citric acid is a weak acid, making it best titrated by using a strong base, such as sodium hydroxide. The combination of a weak acid and a strong base would result in an endpoint that corresponds to the range of phenolphthalein indicator approximately a pH of eight. Image A Phenolphthalein is composed of C14H20O4, as shown in the image above and can…
This paper describes the process by which a three-component mixture was separated and identified. The mixture was separated with the aid of a separatory funnel and various solvents acids and bases. The compound was found to be comprised of meta-nitroaniline, naphthalene, and benzoic acid / 2-napthol. All three of them are organic compounds with melting points in the order they were listed 111-114, 79-82 and 121-122/121-123 °C. the percent yield of each component was also calculated at the end…
3.2. Chemical quality parameters and pH value:- 3.2.1. Chemical quality properties, pH values and total plate count (TPC):- Total volatile basic -nitrogen (TVB-N), the peroxide value (PV), pH and total plate count (TPC) are good index to determine the freshness and quality of fishes and their products. Data presented in Table (4) show the values of TVB-N, PV,…
The influence of selected variables such as pH of phenol solution, concentration of hydrogen peroxide, concentration and the volume of phenol to be treated was studied to find the degree on the degradation of phenol. The influence of these variables on the degradation of phenol using H2O2 by interpreting the TOC results is presented in the following sections. 3.1 Effect of pH The phenol degradation with different pH is shown in Figure 3. As it is clearly seen, a higher pH favors the removal…
Purpose Ibuprofen is one of the most common over-the-counter medications. It reduces pain and inflammation by limiting certain hormones. The drug is taken orally, usually in the form of a pill, and is absorbed into the bloodstream once it dissolves. Both human saliva and human stomach acid aid in dissolving the pill. Human saliva has a pH of about 6, and stomach acid has a pH of approximately 2. The purpose of this investigation is to discover whether the pH of a solution will affect the time…
English:"). Alkalis is any kind of substance that can produce OH ions, hydroxide ions, in water, which can also be known as 'basic', or 'basicity' ("GCSE CHEMISTRY - What is an Alkali? - What is a Base? - GCSE SCIENCE."). Litmus is a weakly acidic, organic…
Therefore, the structural and optical characterization of prepared samples was carried out by using these instruments. 3.2 Synthesis of ZnO Nanostructures ZnO nanoparticles were prepared by using the following reagents : Starch solution Zinc nitrate hexahydrate {Zn〖(NO_3)〗_2 .6 H_2 O} Sodium hydroxide { NaOH) Freshly prepared ammonia solution. In order to prepare 0.01M of ZnO nanoparticles, the following steps were followed: The 0.01 M of Sodium hydroxide { NaOH}…
Zinc was used as a known based on the abundance of the element. Also, zinc acts as an example for how to observe acid and base reactions. When at first submerging zinc in the H2SO4 it seemed as if the zinc was nonreactive; however, after some time bubbles started to form a layer on the zinc indicating that a chemical reaction was occurring. The long wait time associated with…
