This week's reflection assignment consists of one video. It features Mr. Larry Potterfield (founder, and CEO of Midway USA) as the presenter. The video is titled "Gunsmithing: How to properly polish the metal parts on a Remington 700". Mr. Potterfield begins his first video by stating the objective, polishing metal parts. In his hands, he holds the barrel of a Remington 700 series rifle. It appears as if the rifle has definitely seen some cleaner days, in my opinion. This is a skill every…

1. In our notes, we reviewed the Major mineral: Sodium. We know from news and health professionals, our intake of sodium is well over recommendations for our bodies need. List three specific changes you could make to your diet to decrease your sodium intake. • Eat more fresh fruit and vegetables since they are low in sodium. I have also learned that canned and frozen fruits are also low in sodium. • When buying frozen vegetables I have learned that reading the label will help you to…

Out of many early photographic processes, I select the Anna Atkins Photographs of British Algae: Cyanotype Impressions, 1843 Cyanotype. I select this process because the color of this picture is very different to the others in the lecture making this photography stand out and get my attention. While I was doing my researches, I found out that the process to make this picture is not complicated, does not require a lot of materials, and needs a negative image which reminds me of the class activity…

coupling agents to produce an azo dye. The products are mainly ortho and para due to the reaction being an electrophilic aromatic substitution Reaction: p-nitroaniline p-nitro benzenediazonium chloride Para-red Procedure: Production of para-Nitrobenzenediazonium chloride: Prepare 7% NaNO2 by dissolving 7 g of NaNO2 in 100 mL water and in another flask, dissolve 0.4 g of sodium acetate in 3 mL of water. Keep these solutions in ice water bath. Place 0.7 g of…

The chemical reaction can be dangerous I used the, A: soap and bleach and B: soap and water. The reaction in A as the week pass the soap starts to get smaller and smaller, on the left and the right it got white a little. The chemical reaction on A is that the bleach got clear and light at the soap that have been use in the experiment. In Bowl B the water and soap that have been used in the experiment was breaking up, getting lighter. In bowl B the soap took away the walker as the week have…

Sodium diethyldithiocarbamate, limiting equivalent conductance (Λ0), ion association, activation energy and thermodynamic functions. Introduction: The measurement of electrical conductivities of dilute solutions of salts or complexes is considered to be one of the important methods for studying the ion-pair or multiple- ion association not only in aqueous solutions but also in non-aqueous or mixed ones 1-4. Also, conductivity measurements were used to evaluate the hydration free energy of some…

DISCUSSION 6.1 FTIR SPECTROSCOPY It was observed from the FTIR graph that there was no shifting of peaks of metronidazole i,e., characteristic peak of the amine group (N-H streching) present in imidazole nucleus at 1030 cm-1 and presence of NH2 group at 3298 cm-1 in formulation. Hence, there was no interaction between drug and polymer. 6.2 METRONIDAZOLE MICROSPHERES 6.2.1 Optimization of speed (rpm) for preparation of microspheres Metronidazole microspheres were prepared using emulsion…

I. Abstract The experiment was about using a method of recrystallization to reform benzoic acid and unknown compound, and identifying that compound. The main principle is the polarity and solubility of compound. The compound was dissolved completely with distilled water in hot temperature and reformed back in cold environment. After the experiment, there were up to more than 50% of the compound being recrystallized and the unknown compound had the melting point at 165.2oC. The experiment…

before the filtration process Is because the sucrose would not be pure enough and would have a very low percentage composition due to the fact that it would have many impurities from other components. The impurities will be in the Sucrose because it is insoluble and does not dissolve in DCM. Thoroughly stirring the mixture is required before filtration to make sure all the other components are dissolved in DCM excluding the Sucrose. So initially, the Solid here which is Sucrose will remain…

DEVIATION BACKGROUND: On 07/28/2017, During the inspection of PRODUCT A on TP- 18, while the operator was transferring the coated tablets into a plastic scoop, which is used to load the coated tablets into the printer product hopper during the printing, what appeared to be a live and small gnat fly was observed inside the product bag. This was discovered after the operator pulled the product liner off the coated drum to pour the remaining tablets into the scoop. Per routine procedure, during…
