Separting the Components of Panacetin Essay Example for Free

Separting the Components of Panacetin Essay The purpose of this experiment is to investigate the composition of a simulated pharmaceutical preparation Panacetin, a proposed type of pain-killer. Panacetin is typically made up of sucrose, aspirin, and acetaminophen, but the third component in this experiment is unknown. The unknown component is suspected to be a chemical relative of acetaminophen, either acetanilide or phenacetin. Using techniques such as extraction, evaporation, and filtration, the three components will be isolated based on their solubilities and acid-base properties. The percent composition of Panacetin will also be deduced based on the masses of the three dried components; this is done to verify the composition attained is consistent with those listed on the preparations label. As a result of this investigation, my teammates and I allowed the Panacetin to undergo gravity filtration and separation techniques in order to identify whether there are any discrepancies in the components of the Panacetin. Furthermore, recrystallization and purification methods were used to determine if the unknown substance were similar in properties to either of the suspected unknown substances by comparing factors such as melting points to the chemical properties of phenactin and acetanilide. The results were as expected, based on the molecular weights and ratios of each separated chemicals, as well as the boiling point of the unknown it was determined that these ranges were close enough to indicate that the label is reasonably accurate in its composition. To add on however the identity of the unknown component differed from what the label indicated. In the end, the percentage composition attained based on our observations and yield confirmed that indeed the chemical composition of Panacetin were as indicated on the preparations label. The identity of the unknown component however suggested that the preparation did not contain acetaminophen as indicated, but instead was consistent with the chemical properties of acetanilide.

Bram Stoker’s Dracula Essay -- English Literature

Bram Stoker’s Dracula Bram Stoker’s Dracula is a classic example of Gothic writing. Gothic writing was very popular in the 18th and 19th centuries. In the early centuries, Gothic writing would frighten the audience and it was also used as a style of architecture. Dracula, which was first published in 1897, would definitely cause a shock as there was a supernatural being, roaming around sucking people’s blood by the neck. Gothic literature usually includes vampires, monsters or some type of ancient mystical creature. It is also set in medieval castles with secret passages, dungeons and ghost places. There are various types of Gothic literature such as romance and horror. There is just usually horror used but mixing both has also become very popular. Romance on its own was very well-liked in the 19th century. The word Gothic actually comes from the Goths language. A Goth was considered one of a German tribe who invaded Eastern and Western Europe. Gothic was a type of architecture prevalent in Western Europe in the 12th - 16th centuries, it was barbarous, rude and uncouth. Dracula contains a lot Gothic conventions which incite the reader. A convention is the main point of a specific type of writing, for example in Dracula there is the use of journeys/quests, diaries, letters, journals, weird places and strange creatures. These conventions are essential in the story of Dracula and it is important to understand them. Dracula, just like any other gothic piece of writing has a villain/vampire-Dracula, a hero-Jonathan Harker and a victim-Mina. Van Helsing also plays a main role as the slayer of Dracula. Chapter 1, like a lot of the other chapters is written in journal style. This journal is of the main ... ...safe and also the plan to kill Dracula. There is more than one convention but still it will not excite the reader as much as the other chapters. Bram Stoker has created such an effective piece of Gothic Writing as the reader can feel how it would be if they were in the same predicament as some of the characters such as Mina and Jonathan. The conventions express one’s feelings out clear like all the opinions in the journals and the letters to each other. Suspense and fear are something that people express in their own way, not everyone can find the same thing frightening. Some people may just be scared of seeing Dracula and the way he kills everyone by sucking their blood, other people may fear turning into a vampire or becoming a victim. He tries to make us see how it would feel like, if there was a blood thirsty monster staring at you, ready to pounce!

Michael Jackson Biography

Michael Jackson Michael Joseph Jackson was born on 29 August 1958 in Gary, Indiana, USA. His father was Joe Jackson. His mother was Katherine Jackson. His siblings are Jackie, Tito, Jermaine, Marlon, and Michael, Rebbie, La Toya, Randy, and Janet Jackson. American superstar Michael Jackson has entertained audiences his entire life. In the early 1960s, the older boys Jackie, Tito and Jermaine had begun performing around the city; by 1964, Michael and Marlon had joined in. Michael's singing and dancing talents were amazingly mature, and he soon became the dominant voice and focus of The Jackson 5.In 1969, the boys were producing back-to-back chart-busting hits as Motown artists (â€Å"I Want You Back,† â€Å"ABC,† â€Å"Never Can Say Goodbye,† â€Å"Got to Be There,† etc. ). Behind the scenes, Joseph Jackson pushed his sons to succeed. He was also reportedly known to become violent with them. Michael and his brothers spent endless hours rehearsing and polish ing up their act. At first, the Jackson 5 played local gigs and built a strong following. They recorded one single on their own, â€Å"Big Boy† with the B-side â€Å"You've Changed,† but it failed to generate much interest.The Jackson 5 moved on to working an opening act for such R artists as Gladys Knight and the Pips, James Brown, and Sam and Dave. Many of these performers were signed to the legendary Motown record label, and it has been reported that Gladys Knight may have been the one to tell Motown founder Berry Gordy about the Jackson 5. Impressed by the group, Gordy signed them to his label in 1968. At the age of 13, Jackson launched a solo career in addition to his work with the Jackson 5. He made the charts in 1971 with â€Å"Got to Be There† from the album of the same name.His 1972 album, Ben, featured the eponymous ballad about a rat. The song became Jackson's first solo No. 1 single. In August 1994, Jackson announced that he had married Lisa Marie Pr esley, daughter of rock icon Elvis Presley. The couple gave a joint television interview with Diane Sawyer, but the union proved to be short-lived. They divorced in 1996. Some thought that the marriage was a publicity ploy to restore Jackson's image after the molestation allegations. Later that same year, Jackson wed Nurse Debbie Rowe. The couple had two children through artificial insemination.Son Prince Michael Jackson was born in 1997 and daughter Paris Michael Jackson was born in 1998. Rowe and Jackson divorced in 1999 with Jackson receiving full custody of their two children. He would go on to have a third child, Prince Michael Jackson II, with an unknown surrogate. In 2002, Jackson made headlines when he seemed confused and disoriented on stage at an MTV awards show. Soon after, he received enormous criticism for dangling his son, Prince Michael II, over a balcony while greeting fans in Berlin, Germany.In a later interview, Jackson explained that â€Å"We were waiting for tho usands of fans down below, and they were chanting they wanted to see my child, so I was kind enough to let them see. I was doing something out of innocence. † But many were unforgiving of the star's behaviour, with former fans and media outlets clamouring to have Child Protective Services take Jackson's children from him. That is some information of the big list of accomplishments of Michael Jackson. By Doron Cassell

Medical Records and Privacy of the Famous - 1140 Words

Medical Records and Privacy of the Famous Privacy seems to be something that many people desire, but is becoming less and less available. With all the new technology, it is easier than ever to invade someone’s privacy. With cameras everywhere, from ATM’s to people’s cell phones, it is difficult for anyone to do anything that can be kept to one ’s self. While privacy is a right that the average person doesn’t normally struggle with, it is a problem that celebrities encounter everyday. Paparazzi are constantly following these famous people around as they do their everyday things like shopping, playing with their children, partying, or simply hanging in their homes. It is basically the price to pay to be famous. While these†¦show more content†¦It is obvious that celebrity news is an outlet that sells, as seen by the numerous tabloids and entertainment shows. The public has an interest in what is going on in the lives of these rich and glamorous people. This brings on a form of mediated voyeurism, which can be defined as, â€Å"the consumption of revealing images and information about others’ real and unguarded lives, not always for the purpose of entertainment but frequently at the expense of privacy and discourse, through the means of the mass media† (Calvert, 2000). Basically saying that the public has a need to see these famous people and learn about their lives, even at the risk of invading their privacy. The tabloids simply exploit the public’s desire to learn these things, regardless of the ethical issues of invading a human being’s privacy. They know people will buy it and that they will make money. I think that to be an ethical journalist it is important to empathize with the person whose life is about to be splashed on the papers. Of course there is the matter of getting the story and pleasing the readers and the editor, but it should take into account the public’s real right to know. A story about the health of someone like the President of the United States might be something worth printing, because knowing how he is medically is of public interest because this is a man that is running the country.Show MoreRelatedThe Invasion Of Privacy And Privacy1399 Words   |  6 PagesCelebrities; They Have A Right To Their Privacy Too   Ã‚  Ã‚   Invasion of privacy occurs way too often in society.
