Zedina Martin Dr. Adair English 201 8 March 2018 When there is love anything is possible, not! The poem “The Passionate Shepherd to his love” is a pastoral and romantic poem by Christopher Marlowe that has a focus on the Shepherd’s love. The speaker of the poem is the Shepherd. The poem “The Nymph’s Reply to the Shepherd” is a poem by Sir Walter Raleigh in response to Marlowe’s poem. A Nymph is the speaker of the poem. Raleigh’s poem is a direct mockery of Marlowe’s poem and all the claims and…

John Dalton was an English chemist, physicst and meterologist. Might be familiar with "Daltons Law of Partial Pressures" which is a law still used today, or "Daltonism" also reffered to as color blindness. Dalton was born in Eaglesfield, England on September 6th, 1766. He lived a great life until his death on July 27, 1844 as he died of a stroke in Manchester, England. John Dalton was born into a strong Quaker family (family thats known as "Religious society of friends". John had 2 survivng…

the cell that are more hydrophobic (water-fearing) and other parts that are hydrophilic (water-loving). The cell membrane is mostly hydrophobic and the cytosol is mostly hydrophilic. We made predictions of where the drugs would reach giving their chemical structure. This…

In Co(NH3)6Cl3, since the complex has a total charge of zero, ammonia has an oxidation number of 0, chlorine has an oxidation number of -1, cobalt has an oxidation number of +3. Therefore, there are four electrons in the d orbital of a cobalt in this complex. Figure 8 gives the possible high spin and low spin combinations for four d orbital electrons. The high spin config- uration has four unpaired electrons and the low spin configuration has two unpaired electrons. Figure 7. High and low…

In Greek, this is an onomatopoetic word. This means it’s a word that imitates the sounds associated with the objects or actions it refers to (like the word buzz in English sounds like the sound a bee makes when he is flying around). The word zeloo imitates the sound of boiling water, and it literally means to bubble over because it’s so hot! In a positive sense, zeloo is to be zealous in the pursuit of good, to desire earnestly, to strive after, to pursue, to be eager to possess. In the…

Electrical properties Figure. 8 shows the temperature dependence of resistivity of the Co(II), Ni(II) and Cu(II) complexes. As seen, the data reveal a semiconductor behavior where the resistivity decreases with the increases of temperature. The decrease of the electrical resistivity with increase of temperature is resulted from the increase of the charge carriers that can overcome the energy barrier and participate in the electrical conduction where in metal complexes, the metal…

1.7.3.4. Hydrogen sulphid test (MacFaddine, 1980): Tubes of triple sugar iron agar media were inoculated by suspected culture through stabbing into the butt and the slant then covered with sterile melted paraffin wax and incubated anaerobically for 48 h at 37°C, appearance of blackening in the butt indicates H2S production. 1.7.3.5. Sugar fermentation test (Willis, 1977): Suspected culture was inoculated to 1% peptone water tubes containing 2% bromocresol purple and 1% quantities of the…

Tyler White CHEM151LL 13851 07/18/2017 Mole to Mole relationship and Empirical formula of a Hydrate Purpose: The purpose of this lab experiment is to determine the molar ratio between substances, and to write chemical equations. The second experiment is to determine the ratio of water in copper, and magnesium, which is obtained through burning the vapor using the Bunsen burner. Materials: Because the experiments were conducted online there wasn’t any use of materials, only digital ones, for…

1. Observation. - Compound X is a white powder. It is a solid. 2. Questions. - What is compound X? - What will happen when compound X is heated and reacted with C20H14O4 (phenolphthalein – an acid-base indicator)? (1) - How does compound X react with C20H14O4 (phenolphthalein)? (2) - How does compound X react with water? (3) - How does compound X react with hydro chloric acid (HCL)? (4) 3. Predictions. - Compound X is calcium carbonate (CaCO3). - (1) When compound X is heated and reacted with…

1 WRITTEN ESSAY Paragraph 1 The FePO4 crystal is examined at various temperatures ranging between 294K and 1073K by neutron powder diffraction. At relatively low temperatures, FePO4 adopts an α-quartz structure, which is tetrahedral. High pressures causes a phase change to a more dense octahedral structure, which is known as β-phase. The transition temperature is 980K. Cutoffs can be observed during the firstorder transition,. For α-phase, the increases in cell parameters…
