My comprehensive treatment plan for Rangi will include restorative treatments, along with a caries management plan to avoid secondary caries and enhance enamel remineralisation. Furthermore, adequate preventive periodontal measures may halt the progression of Rangi’s gingivitis. I will plan Rangi’s treatment according to his caries risk status. According to the protocols for the clinical management of caries by risk factor level (CAMBRA), this is a positive measure of successful caries…

Objective The purpose of the experiment is to synthesize a compound with an organometallic iron-carbon bond and use infrared spectroscopy to investigate the unconventional sandwich structure. In addition, the experiment aims to understand pi-bonding of an arene ring, use cyclic voltammetry to understand the redox capacity of ferrocene, and explore the barriers between formal inorganic and organic chemistry definitions. Introduction Ferrocene was discovered unintentionally in 1949 when Miller…

Curly, So Kinky, So Straight, will determine whether you’re a good candidate for either a Lye relaxer or No-lye treatment. A Lye treatment is generally a faster process, but may not last quite as long. Meanwhile, a No-lye treatment uses calcium hydroxide, which is known to be drying but…

1. What contaminants were found in the surface water samples? What contaminates were found in the ground water samples? The contaminants found often in surface water is waste and chemicals. The contaminants that are found in ground water samples are acidity due to deterioration of pipes and metals that are found in the ground. 2. Why might groundwater and surface water have a different contaminants? There are specific contaminants that affect each area that are not in other areas such as rusty…

The solution that was tested was a mixture of sodium hydroxide (NaOH) and zeatin and water. The sodium hydroxide was added to the solution to activate the enzyme. If everything else remains constant in the experiment, what are the determining factors? In this experiment, three different concentrations will be tested to determine which…

(5 mL) and sodium hydroxide (10 mL) were added. The mixture was filtered and rinsed with cold ethanol and cold water to remove its brown color and a crude weight was taken (0.238 g, 0.936 mmol) The resulting solid was placed into a 25-mL round bottomed flask along with maleic anhydride (0.245 g, 2.50 mmol) and triglyme (4 mL). Then, the flask was fitted with a reflux condenser and refluxed in a sand bath for 5 min. The soln was cooled and had ethanol (2mL) and sodium hydroxide (6 mL) added. The…

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 hydroxide pentahydrate (TMAOH 98% in purity) was used as received from Alfa Aesar GmbH & Co KG. 2.2. Syntheses 2.2.1. NaY…

6. If t-butyl bromide was used as a substrate instead of t-butyl chloride the reaction rate would stay the same. The mechanism will still be SN1 reaction for the same reasons as t-butyl chloride. Such as, t-butyl bromide is tertiary alkyl halide like t-butyl chloride which will also favors SN1 reaction when reacted with water, a weak nucleophile. It will also form 30 carbocation which are more stable in SN1 reaction mechanisms as having more R groups (CH3 in this experiment) on the carbon with…

Mr Jose Pool Chemistry Equilibrium system and stress factors Jake 14/08/2014 Pool Chemistry Introduction Pools with crystal clear water look inviting on a hot day however there may be unseen hazards. Invisible dangerous pathogens and microorganisms may be present in pools that aren’t treated properly and can result in harmful side effects like swimmers ear or diarrhoea. Disinfectants are used to treat pools and chlorine is by far the most commonly used. Hypochlorous acid (HOCl) is the…
