Chemical Synthesis

The experiment is to observe a variety of chemical reactions and to identify patterns in

The wire reacted with the solution to yield copper; any remaining aluminum was dissolved with a few drops of 6M HNO3. Following the isolation of the copper, it was separated from the solution with a Büchner funnel and flask. A piece of filter paper was weighed, and its mass was recorded. Then, the filter paper was placed on the vacuum flask, which was turned on, and the copper solution was poured over it. The copper was also rinsed with 95% ethanol solution before being set on a paper towel to dry. Finally, one day after the previous step, the copper was weighed, and its mass recorded. The recorded masses were then used to determine the mass of copper, chlorine, and water in the unknown copper chloride hydrate. The resulting masses were used to find the formula of the unknown copper chloride hydrate according to CuxCly•nH2O.

The purpose of this lab was to utilize roasting, smelting, spectroscopy, and the carbonate test in order to determine the identity of an unknown copper mineral. I determined that the most useful of these tests in determining the mineral was roasting because it provides a fairly accurate percent composition of copper in the unknown mineral.

The two essays that I choose for the synthesis essay are Parkinson’s Alley by Joy Horowitz and The Environmental Issue from Hell: Global Warming Is the Great Moral Crisis of Our Time by Bill Mckibben. Parkinson’s Alley is about residents in California’s Central Valley town of Visalia who have been diagnosed with Parkinson’s. This part of California has the highest number of people diagnosed with the neurodegenerative disease. The pesticides that are used in the surrounding farms seeps into the water that the residents use every day, causing them to get the disease. The Environmental Issue from Hell: Global Warming Is the Great Moral Crisis of Our Time is about how global warming is a moral crisis that, if not combated

Solutions of 6M H2SO4, 6M NH3, 6M HCl, 6M NaOH, and 1.0 M of NaCl, 1M Fe(NO3)3, 1M NiSO4, 1M AgNO3, 1M KSCN, 1M Ba(NO3)2, and 1M Cu(NO3)2 were given in separate test tubes. The color of possible precipitates, ions, acid-base behaviour, odor and solubility rules were conducted and were reported in Table 1. The key information about a mixture of two solutions was

A twenty-five-year old Caucasian female presented to the office with burning with urination. External inspection of the patient’s labia majora revealed genital herpes. Herpes simplex virus infections associated with the genitals are usually deemed type two (Uphold & Graham, 2013). The patient was placed on acyclovir for her outbreak. The current dosage that she is being placed on is 400 mg orally every eight hours for ten days (Medscape, n.d.). There are no medication contraindications for this drug; however, one should not use neomycin orally due to an increase in nephrotoxicity and or otoxicity if the two are taken together (Medscape, n.d.). Other medications such as bacitracin and cidofovir should also not be used with acyclovir due to an increase in nephrotoxicity and or otoxicity if these are

In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product, tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield benzoin. Thiamine catalyst along with water and ethanol were added to the benzaldehyde, then NaOH was added until the solution turned yellow. After recrystallization, the product was benzoin. Step two was the oxidation of benzoin to benzil.

According to Hobsin and McCarly, dreams are the result of biochemical and physiological response of the body to chemicals fired by neurons that are arising from the brainstem. This two personalities experimented on cats- which based on research has the similar brain waves and movement similar to humans when asleep. They concluded that dreams are the product of brain cell activation but it does not create any movement in a person's body. Furthermore, they believed that dreams are chemical responses to the brain's activity. The example the lecture cited is when a person is trying to escape in her dream, there will be a message from the brain for the body to start running but there will be no leg movement. This model is called the Activation Synthesis

Briefly present Freud's theory on dreams and how his ideas are distinctly different from the philosophy of the Activation-Synthesis Model. Freud believed manifest content/dream images brought out repressed wishes/wish-fulfillment and urges, and latent content/ disguised psychological dream meaning. Also, dream functioning was a release of unconscious and inappropriate urges. Images in dreams had different symbolism's such as, an elongated object represented male genital organ and ovens represent the female genitals. Researchers Robert McCarley and J. Allan Hobson created a model called Activation-Synthesis in which it suggests dreams are a way the brain makes sense of the activities while sleeping.

Finally, in his sixth and seventh chapters, Bodnar explains some common misconceptions that have come about over years of immigrant study. First, for example, most scholars write about the opportunity available to immigrants in America, that being the main reason they emigrated; this is not true. Most immigrants emigrated for the good of their families, and once they got to America, moving upward was generally not realistic for a few (if not many) generations. And, overall, most immigrants could find horizontal mobility, but not vertical.13 Second, many scholars concentrate on the immigrant ghetto and associate immigrants with only passing through slums and inner city dwellings like tenements. Bodnar points out that in the early third

There are many hallucinogens including plants and fungus, however, there are many synthesized hallucinogens as well. This paper will be focusing on the synthesized hallucinogen called Lysergic acid diethylamide (LSD). This drug is not coming from a natural plant because it was “first synthesized in 1938, is an extremely potent hallucinogen. It is manufactured from lysergic acid, which is found in ergot, a fungus that grows on rye and other grains” (Anderson, 2014). Compare to other drugs, LSD is not as addictive, but this drug has negative psychological side effects as well.

. Ecologically safe methods for the synthesis of five-membered and six-membered cyclic carbonates by the reaction of transesterification of dialkyl carbonates with dihydric alcohols will be developed.

Abstract: Synthesis of new compounds 2-(bis((1H-benzo[d]imidazol-2- yl)methylthio)methyl)-1H-benzo[d]imidazole (6a) and 2-((((1H-benzo[d]imidazol-2-yl)(((5- hydroxy-1H-benzo[d]imidazol-2-yl)methyl)sulfanyl)methyl)sulfanyl)methyl)-3H- benzo[d]imidazol-5-ol (6b) were carried out under two different reaction conditions, namely the conventional method and microwave irradiation conditions. The compounds (3a,b), (5a,b) and (6a,b) were synthesized by using microwave methods which showed decrease in the reaction time and increasing in the yield as shown in Table (1). The structures of the synthesized compounds were confirmed by IR; NMR and elemental analysis. The antimicrobial activityof the synthesized benzimidazolemethanethiol derivatives

Solutions of CuSO45H2O (0.506 g in 10mL water, 3.17E-3 mol) and ammonium peroxodisulfate (1.030 g in 10mL water, 4.51E-3 mol) were prepared and mixed
