Create a 5 pages page paper that discusses tasks in chemistry. 3. From the right-hand side the peaks have been arranged in the following order. acetophenone, p-chlorophenol, benzonitrile, p-xylene, p-dichlorobenzene, ethylbenzene, bromobenzene, toluene, and n-butylbenzene.

4. Discuss each of the chromatograms you have produced in parts 1 and 2 above. Your discussions should make reference/attempt to define by application all of the following: the resolution of peaks, band broadening, mechanism of separation for each technique, the order of elution, mobile phase properties, stationary phase properties, parameters that gave rise to the chromatograms presented and the effect they had on separation with particular reference to the challenges that presented themselves when trying to establish the optimum parameters.

The first two peaks of acetophenone and p-chlorophenol have a high resolution because they have very short elution time. This is because their mobile phase has a low adsorption coefficient as compared to the other compounds. While the rest of the compounds have high elution time.

Some of the peaks have broad bands because of the path, they took to be eluded. It has been found out that some compounds accidentally take shorter routes in the column, therefore they have fine thin bands.

Sample separation depends on the affinity and solubility of the mobile phase on the stationary phase. The samples have been eluded in the order shown above because, acetophenone and p-chlorophenol have low solubility in the stationary phase, therefore they pass the stationary phase very fast.

History of the Conflict between Arabs and Israel. The work is to be 7 pages with three to five sources, with in-text citations and a reference page.

I will pay for the following article History of the Conflict between Arabs and Israel. The work is to be 7 pages with three to five sources, with in-text citations and a reference page. For instance, the Israeli name for the war is the ‘war of independence’, while the Palestinians call it al-nakba which is the Arabic word for Catastrophe. The facts which can be ascertained from historical documents and reliable sources agree upon a few points (Gerstel, 2004). For example, we can be reasonably certain that the Arab nations did not accept the creation of a Jewish state when British partitioned Palestine into two states. We also know that the armies of Egypt, Syria, Lebanon and Jordan attacked the newly formed state soon after the British left. Still, we find differing opinions as to why the war was started and which party provoked the other into taking offensive action.

For instance, the pamphlet (Source A) written by the PLO titled History of Palestine (1984) examines and describes the issue by painting the Israelis in an obviously bad light. It says that the peaceful villagers of Deir Yassin were attacked by the Zionists and more than one hundred and fifty men, women and children were killed and mutilated by the Jews. The PLO also gives the reason for this attack and calls it a scare tactic which was supposed to cause panic and make the Palestinian population leave the country in a hurry. Scared for their lives, the Palestinians flew from their homes and were not allowed to come back after the war-making them refugees by default.

The entire blame for the war is laid at the feet of the Israelis, and the source fails to make any mention of the nations which attacked Israel as soon as it emerged as a country. It does not make any allowances for the fact that there could be another possible side to the same argument. It uses powerful words which could be considered hate material in many civilised countries. Then again, the application of such tactics is to be expected of the Palestinian Liberation Organisation since they had been at war with the Israelis many years before this document was ever created.

I need help creating a thesis and an outline on Human Service Development Policy in Allegheny County. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. Generally, Allegheny County, as from the case study was facing a lot of problems in leadership which was the main expediter for the rest of the challenges that people faced and the human services that they did not receive.

How the Case Study Offered Support for or against the Rational Model

Basically, in the rational model concept, the government is treated as the primary factor. additionally, it has the responsibility of examining a set of goals, evaluating them according to their utility and then picking the one that has the highest result. As from the case study, matters seem to be out of hand at first. essentially the rational model process is inflexible in Allegheny County (Morgan 2014). Additionally, through an extensive range&nbsp.of information exchange, prevention, early intervention, case management, crisis intervention, and after-care services. however, there was a high rise in child abuse and neglect, rising poverty, the continued dissolution of the family and the introduction of crack cocaine that affects the Allegheny County dearly.

Furthermore, there existed a series of public hearings calling for sweeping child welfare reforms following the tragic death of a child in care resulted in the resignation of the Department of Children and Youth Services (CYS) director leading to a nation-wide such for a new doctor (Tranter 2008). However, the case study to a particular extent had a big positive impact since the problems are established and identified which would make it easier for the solving process. additionally, there were some prospective leaders like Tom Forrester and David Lawrence who held a philosophy for helping Allegheny County people.

Fortunately, it led to the formation of the Allegheny County’s department of Human Services later on which offered even more services that included mental health, older adults and drug and alcohol services, child protective services, emergency shelters and housing for the homeless, and services for people with a diagnosis of intellectual disability among others.

creating a thesis and an outline on Michelangelo’s Last Judgement. Prepare this assignment according to the guidelines found in the APA Style Guide.

I need help creating a thesis and an outline on Michelangelo’s Last Judgement. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. In this painting, judgment day is depicted and Christ is seen as a “stern judge of the world” (Kleiner, 2009, p.474). The literary sources from which this work of art drew its theme are supposed to be, the Bible, the Divine Comedy and also many folk and traditional stories about the judgment day (Barnes, 1998, p.1). It was Pope Paul III who invited Michelangelo from Florence to Rome and entrusted him with the creation of this painting, also deciding upon the topic of this painting (Paoletti and Radke, 2005, p.501). It was under the loving insistence of the Pope (who was busily reviving the strength of Catholicism in the backdrop of Protestant Reformation) that Michelangelo left his work in Florence and came to Rome. Hence it can be said that this painting embodied the Catholic idea of salvation (Dixon, n.d.). The painting shows all the just figures inside it as ascending to heaven and all the damned figures as being taken downward into the hell (Kleiner, 2009, p.474). The purpose of this painting as seen from the eyes of the Catholic Church of that era was to tackle the ideological spread of Protestantism (Williams, 2004, p.76). The Church was getting aware of the “power of art” and was trying to “exercise some kind of control over the production and consumption images” (Williams, 2004, p.76). In this painting, Michelangelo has “used some…intense colors” and had paid attention to undertake perfect detailing of all the human bodies that he has drawn (Paoletti and Radke, 2005, p.501). It is observed that “each hue is powerfully distinct, yet shot through with lights of other hues” (Dixon, n.d.). The ambience created by this painting is that of great tension and apprehension. This is in accordance with the theme of the painting, which is about the judgment day. The central figure if Jesus as is in all previous judgment day paintings. The raised right hand of Jesus in the painting is supposed to represent the canonical saying, “(He) wrathfully damns the guilty and banishes them from his presence into eternal fire” (cited by Dixon, n.d.). But some critics (Dixon, n.d.. Kleiner, 2009) have viewed the positioning of the hand as depicting uncertainty and ambiguity.
