Strontium chloride hexahydrate Essay Example

Strontium chloride hexahydrate Essay Example Strontium chloride hexahydrate Paper Strontium chloride hexahydrate Paper The following are possible factors that may contribute to acheiving a higher yeild. Firstly, it is possible that there was contamination from outside sources, such as lint or dust particles that could have fallen into the drying precipitate. Secondly are impurities accumulated through water. Non-distilled water can contain many minerals and impurities , aswell as absorbing chemicals in the surrounding air which can skew results. According to the city of Ottawas website, there are many contaminants in water, the two of those being fluoride and chlorine. Fluoride is naturally present in the air and soil, and can dissolve into water. Chlorine is used by the city in the water to kill bacteria. Average tap water contains 0. 7 mg/L of fluoride and 100 ppb, or parts per billion of chlorine. These insignificant substances, in additions to those not named here, can change the way the reaction takes place. Thirdly is lingering moisture, which can be present because of thick acumulation of precipitate which causes moisture to remain at its center. Water could also be present due to outside sources, such as higher than normal humidity levels present in the laboratory or water bottle fights that may have taken place and interacted with the results. To validate this reasoning, another student who acheived a higher yeild, Yannick Brisebois notes in his analysis that he was closely located to the water fight, similarily to this experiment. Lastly, misreaction is another way the precipitate was higher than expected. The reactants could have possibly reacted with the levels of fluorine or chlorine in the water, as covered in the example above. Since perfect reactions are impossible, it is likely that some of the reactants were not used up in the reaction, and were left in the precipitate. This would increase the mass of the precipitate because both the strontium chloride and the copper sulphate were hydrates, which have a higher molar mass than the products because of the attached waters. For example, according to table 2, the masses of the reactants strontium chloride and copper sulphate are 266. 58 and 249. 62 g/mol respectively, while the precipitate, strontium sulphate only has a molar mass od 183. 64. Any ammount of extra reactant would weigh down the mass of the precipitate. 3. The following steps were taken to ensure the reaction went to completion. First, the ammount of transfers were kept to a minimum in order to preserve as much of the orginal reactants as possible. Multiple transfers can cause reactants or precipitate to adhere to the walls of the beakers or the funnel. There are only two transfers present in this procedure. Second, the solutions were dissolved into aqeous solutions to facilitate a reaction and increase the ammount of reaction taking place. Without a solution, the two substances would not have reacted in a solid state. Solutions also increase the likeliness of the most possible reaction, because of its containment, as opposed to a gas, and the potion of the particles within, unlike a solid. Both reactants were dissolved into water in order to maximise the reaction and ensure it took place. The reaction was finally stirred for a mintute to maximise the reaction. The stirring added heat and motion, which is another form of heat, which allows more reactant to react properly. The heat increases the speed at which the particles move within the liquid, which leads to more collisions, and finally more reaction taking place. Finally, the original beakers and the funnel were washed down with water and passed through the filter to ensure all possible remaining reactant had been added to the apparatus. Refrences: 1.

Definition of a Non-Traditional Student

Definition of a Non-Traditional Student On many campuses, the majority of students are nontraditional students. What does that mean? Who are they? Nontraditional students are 25 and older and have returned to school to earn a degree, an advanced degree, a professional certificate, or a GED. Many are lifelong learners who know that keeping their brains engaged keeps them young and vibrant longer. Experts have suggested that continuing to learn can even help prevent Alzheimers disease.

The Times Magazine has named her as â€Å"Dancer of the Country†. She contributed 70 years of her life for the Dance company. Her one more experimentation was dancing and revealing Human movements. Where as Rainer went one step further by becoming a filmmaker. He too looks similar with that of Martha Graham in revealing social events but differed from her from his revelation of the political side of the society also. His work is associated with skepticism. He tried out finding the difference between irony and cynicism which is also a missing concept in the works of Martha Graham. Though both of them had the similar option of revealing what place art has found in the daily activities of the society? But Rainer seems to have gone a little more by finding how he could reveal the concept of changes that take place in a society, where as Graham restricted her works only with human movements. While analyzing the services rendered by both to the world of choreography, Graham seems to have crossed the perfect contributor. Pina Bausch is a choreographer of modern dance. She pioneered the Tanztheatre style of Dance , a leading and influential dance works which came out from the German Expressionist Dance . She was sent to ballet dance in her childhood. Her dance performances includes a lot of German style of dancing and ballet with the concept of male and female interaction . This theme is found in almost all her works. She has given way for a neo-expressionist style, dramatic and surrealist settings in her work of dance. This could be seen in her work Carnations[1983]. She has choreographed on stages with dirt or carnations of water covered over it . Men and women are found flirting tenderly then moving and flying each other violently towards inside. These are the qualities found in her works. Lin-Huai-Min, is the founder of a well known and famous Chinese Modern Dance Group called

Business law - Essay Example 150). The Islamic doctrine would however not apply under the CISG because the convention overrules application of regional laws in international transactions (Schaffer, Agusti and Earle, p. 120). In the case, Bende made a contract with Ghanaian government for deliverables at a price of $ 158500. He then subcontracted to Kniffe who was to deliver the goods at $ 95000. Kniffe however failed to make delivery as the carrier train had derailed. Kniffe’s claim that the contract had been rendered impracticable is valid because the train wreck was unforeseeable and beyond his control. However, the performance is not excused because of the no force majoure clause that was contained in the contract sustains liabilities. The wreck was however unforeseeable (Fox, p. 143). Bende would be entitled to damages of $ 44685. This would include lost profit to which he would be entitled. This is due to compensatory damages doctrine that provides for a party’s restoration to the position he would have been had a contract been fulfilled. This includes profitability (Fox, p. 60). If the parties had agreed that Kniff would merely ship the goods then the risk would shifted from Kniff to either the buyer of Bende, depending on the original contract because property would have transferred to him (Schaffer, Agusti and Earle, p. 728). The importer is likely to win the case. This is because of two factors, the open price term of the contract and the force majoure clause that applies to contracts that have been rendered impossible. Under the open price term, the distributer is bound by the contractual terms that were entered into during contract formation. The force majoure clause also suspends any liability over contractual obligations when activities have been rendered commercially impossible. Adversely unfavorable currency fluctuation, being identified as a factor towards the clause, therefore releases both parties from any liability from the contract. Consequently, the

Glory Movie Essay Example for Free

Glory Movie Essay Glory is both an awe inspiring and heart wrenching movie about the first all black volunteer company to fight in the civil war. The movie starts off with Col. Robert Gould Shaw leading a company of soldiers in Antietam which suffers heavy losses. Soon he is promoted to Colonel and given command to the 54th Massachusetts volunteer infantry; the first all black regiment. The first volunteer to sign up is an educated black man named Thomas Searles who is also Shaws friend. Many more men join the regiment including an escaped slave named Trip, a free black man named Jupiter Sharts, as well as the gravedigger Rawlins. After realizing the regiment in never going to be more than anything but manual labor, Colonel Shaw confronts his superiors and demands to be transferred to somewhere where they will see some fighting or else he will report him to the War Department for suspicious business. Shaws request is granted and is transferred to South Carolina where they successfully fight off a group of confederates. This movie was a huge hit. Released in 1989, it won a total of 16 awards including 3 Oscars and god nominated for 12 more awards. The Director Edward is well-known for his heroic movies that include Glory (1989), and the breathtaking works of art that include Legends of the Fall (1994) as well as modern hits such as Love and other Drugs (2010) and Defiance (20080. Zwick has also been known for his thoughtfulness as a director, and for his record of working with television series and other films as a producer. The movie itself was destined for greatness with huge Hollywood names such as Denzel Washington who played Trip and Morgan Freeman who played John Rawlins also great supporting actors like Matthew Broderick who played Colonel Shaw and Andre Braugher to play Thomas Searles. The movie budget was 18,000,000 and grossed a total of 26,830,000. In my own rating system 5 being the best and 1 being the lowest the movie got a 4. The movie deserved every award it got. There were amazing battle scenes as well as some very emotional scenes as well. Denzel Washington was an amazing actor, the scene where he was getting whipped for deserting (which we later find out was to find shoes) while the colonel was watching was one of the most heart wrenching scenes in the movie. As well as great acting the story never skips a beat. There’s never a dull moment. The movie had a clear plot and you could easily understand why something was happening. The movie gave a realistic view of how hard things were for African Americans were and their hunger to fight for what they believe is right. The historical accuracy of Glory is pretty questionable. It does a good job addressing the hardships and discrimination the 54th did go through. However like all Hollywood history movies it does have its rights and wrongs. Most of the volunteers in the movie were depicted as fugitive slaves when in reality they were free men in Massachusetts. Of the major characters in the movies version of the regiment, only Robert Gould Shaw was a real person. The rest are made up characters. The name of Shaws executive officer (Cabot Forbes) is a combination of the first name from one of the real Shaws friends and the last name of another. Colonel Shaw was a married man yet in the movie it wasn’t shown. Though it may not have been a big point in history it was a big part of Colonel Shaw’s personal life. At the end of the movie it states that over half of the regiment was lost during the assault on Fort Wagner. However, official records state that the 54th sustained 272 casualties, which is closer to 40%. Of these casualties, only 116 were fatalities, just under one fifth of the men to storm the fort, however if you include the 156 that were captured it would bring your total to over half. Most aspects of the movie however are true. When the black soldiers refused pay due to discrimination Colonel Shaw did refuse his pay as well. Against all expectations the 54th rose above that and proved them wrong. They proved their valor and honor throughout several battles during the war. There was a memorial made to Colonel Shaw and his 54th and thus solidifying their regiment as one of the most influential and memorable of all time. Bibliography * Glory. Dir. Edward Zwick. Perf.

Policing Cyberspace on the Internet Essay -- Internet Communication Co

Policing Cyberspace on the Internet The Internet is a method of communication and a source of information that is becoming more popular among those who are interested in, and have the time to surf the information superhighway. The problem with this much information being accessible to this many people is that some of it is deemed inappropriate for minors. The government wants censorship, but a segment of the population does not. Legislative regulation of the Internet would be an appropriate function of the government. The Communications Decency Act is an amendment which prevents the information superhighway from becoming a computer "red light district."

Diasporic Article Critique

We define Diaspora as a movement of any population with common ethnic identity from their settled territory to areas farther away. This is common to populations from countries which are experiencing poverty, economic unrest, and military problems, making it not very suitable for living. This is the situation discussed in the article by Mary Rogan, entitled Girl, Interrupted. She talks about the life and death of Aqsa Parvez, a Pakistani immigrant in Toronto, Canada.The article focused on the life of 16 year old Aqsa, who tried to blend in with the western culture of her new home (Rogan, 2008). The article initially recounts that events that happened the day Aqsa Parvez was murdered by her own father and brother because she allegedly disrespected their culture and religion. The article was nothing more than an account of the things that happened before and after the death. It tried to fit in the pieces that led to the death of the teenager, coupled with the statements given by two of her closest friends.If you look at the situation in a spectator’s perspective, you would see that it was nothing more but a case of domestic violence, with the father overly beating the child for not following his orders. However, if the case is viewed in a cultural or religious perspective, it would reveal a different story. Diaspora in the context of Aqsa Parvez’ situation would mean moving from her place of origin towards Ontario, while brining with her all her cultural and religious beliefs (Berns-McGown, 2008).She was a from a Muslim family, and devout one at that, which is why every aspect of their culture should be followed, and deviating from it would mean disrespect, and should be dealt with accordingly. Aqsa Pavrez is born and raised in the Islam culture, so she has to adopt in her life every teaching that the culture presented to her. The article Girl, Interrupted focused on one symbolism all throughout the article, and that is the wearing of a Hajib. Muslim women were regarded as the treasures of the religion, which is why they have to be covered all over, as much as possible, not revealing an inch of their naked skin.For those living in Muslim countries, women were clad in robes and cover their face, revealing only their eyes. But for the case of Aqsa Pavrez, she was only required by her parents to wear a Hajib, a cloth that would cover her head and hair. This situation is a manifestation of cultural diaspora, wherein Aqsa Pavrez and her family carries with them the religious and cultural beliefs and practice of their homeland. However, since Ontario is different from where they came from, they have to somehow adapt and adjust these practices to match the place.Aqsa Pavrez and other women from the same culture and religion were not anymore required to be clad in long robes just to cover every inch of their skin. They were instead required to wear lose shirts and large jeans, and to wear a Hajib to cover their head. For those who have strongly adhered to their cultural and religious practices, complying with these guidelines was easy. They are somehow able to fit in with the new environment, but are able to maintain and preserve with them the teachings of their culture and religion.But Aqsa Pavrez was different. According to the article, she did not despise wearing their traditional clothing, but instead, she wanted to wear it according to her choice. She wanted to have freedom in choosing what to wear, freedom of expressing herself, especially since she’s a teenager, with friends who are very much different from her. She somehow wanted to blend in, and the practices that she was accustomed to were hindering her from doing so. In a Diasporic perspective, we can say that indeed, there are people just like Aqsa Pavrez.They don’t hate the culture and religion they grew up with, but they also wanted to enjoy what other people are enjoying. The cultural practices that she was expected to follow were hin dering her from doing the things she wanted, which is why most of the times, she broke the rule set by her father and older brother. In the context of Diaspora, the people who settle in foreign lands such as this were expected to alter the beliefs and practices that they have brought with them. They are in a different land, and not all of the cases that they grew up on would apply.If we are to judge the actions of Aqsa Pavrez, she was merely adapting to the new environment, and was trying to mix the culture that she grew up on, with that of the foreign land they have settled in (Sen, 2006). This action is very much expected, though there are some constraints that she has encountered. First of all, she was still in her youth, and she couldn’t possibly stand on her own feet considering her age. It was too early to become independent, so no matter what her desires are, it is impossible to put it into fruition.Her family, especially her father and brother, hindered her from doing so, primarily because they wanted her to retain the practices and beliefs that they grew up on. The sad thing though, for the case of Aqsa Pavrez is that she was not given the chance to grow up. She died before even reaching the point where she can decide on what she wants. The title could be wrong because girls like Aqsa would still need intervention. What could be more appropriate is that, it is a Life, Interrupted.
