Essay on Synthesis and Chemistry of K2S2O8 - 2122 Words

SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment, a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion, S2O82-, was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability, coupled with its strong oxidizing ability allowed for stabilization of the unusual oxidation state of 2+ for silver which was observed by preparing an analogous silver (II) complex by reacting silver (I) nitrate with ammonium peroxodisulfate in the presence of pyridine.

Preparation of potassium peroxodisulfate A potential set-up was prepared wherein the 25 x 150 mm test tube was filled with K2SO4 (30mL, 0.15 mol) saturated at 0  °C in 5M H2SO4. The test tube was immersed in ice, power supply was adjusted to give the solution a current of ~3.0 amps. Current was read and recorded as accurately a possible, as well as the time over which electrolysis was carried out. K2S2O8 precipitated over a period of 45-50 minutes during which the temperature was maintained close to 0  °C (~8  °C or lower) during electrolysis. Crystals were collected in a Buchner funnel, washed with alcohol, then ether, then transferred into a sample tube for storage. B. Reactions of Peroxodisulfate Ion A saturated solution of K2S2O8 in water was prepared and the following reactions were carried out. The results were compared with similar reactions using hydrogen peroxide. 1) Acidified KI solution, warming gently 2) Silver nitrate solution 3) MnSO4 solution in 2M H2SO4, containing 1 drop of AgNO3 solution 4) Titanium (IV) sulphate solution C.

Coming Together with Music free essay sample

A wrinkled old woman waves hello as she heads indoors to pick up her usual Sunday lunch at the food court. She weaves her way through the crowd around us, navigating past an Israeli family, a few Spanish-speaking men, and a group of Red Sox bound Bostonians. Home to 18,000,000 tourists a year, the lively historical marketplace, Faneuil Hall, is not an easy location for her to pass through. The member of the band whose part is the least busy — either my mom, my sister, or I — waves hello, letting the musical harmonies wane from three parts to two, and back to three again after she picks up her bow and continues playing. Playing music as a part of the Performance Roster on the buzzing streets of Faneuil Hall Marketplace is not about a perfect performance. I’ve thought it started to rain, only to realize it was actually bird poop dropping onto my head. We will write a custom essay sample on Coming Together with Music or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page I’ve witnessed our whole stack of business cards fly away with a breeze. I’ve smiled so big while playing watching a little girl dance that I couldn’t possibly run a steady bow on the strings of my violin. These little moments, gems of live, outdoor performance, bring the focus of my music on joy, rather than flawlessness. My family band, Tatu Mianzi, got together years ago for a family wedding. Over the years, we’ve moved far beyond the classical genre. These days, in a typical set, we might bounce from a Brazilian Bossa Nova to Scottish Fiddle, from Hava Nagila to Eleanor Rigby. We focus on learning music from as many regions of the world as we can, reaching out to specialists to teach us their traditions. It doesn’t matter that our band – made up of two violins and a cello – learned to play tangos from an accordion player, or jazz from a saxophonist. Music is music. We take our eclectic shows all over the country and the world, performing more than 50 concerts a year. When we play in schools, I ask the kids, â€Å"Where do you want to travel today?† A girl in the front calls out a country, probably from her family heritage, and we play her a song from that region, watching her face light up as she listens to her culture come alive. I’ve played some songs in my repertoire well over 500 times, yet performing with my band never gets old. I’m no longer thinking about playing the right notes or bowings. Instead, I’m listening closely and responding to what my sister and mom are playing as we take turns trading off the melody, choosing a bass line, and improvising harmonies. I play from the heart, not the page. Back at Faneuil Hall, people with seemingly nothing in common – no common language, different skin colors, wide age gaps – enjoy each other as they listen to us play. They start to clap and dance together, and I dance too. In these moments, letting my emotions take over and seep through me, at the expense of a few lost notes, is okay. In fact, it’s encouraged. While playing in Tatu Mianzi is technically a job, and it’s great to make money, I gain so much more from my trio than the tangible. In a time when my country seems divided – politically, economically, and racially – our music is a catalyst, melding people together who would normally be at odds. Our music creates a community of people, if only for a few minutes at a time, that gets along. They stop to listen, opening themselves up to their emotional impulses and refreshing themselves for whatever lies ahead. I too am refreshed. Goodness can be so simple.

The Dissolution Of The Manasteries Essay Research free essay sample

The Dissolution Of The Manasteries Essay, Research Paper Background to the Dissolution The Dissolution of the Monasteries and the events which followed, were all brought approximately as a direct consequence of the interruption with Rome. The ground for the interruption, lies merely in Henry? s defeat at his inability to procure a divorce signifier his married woman Catherine of Aragon, and a approval from the Pope for his new matrimony to Anne Boleyn, although arguably, there was a demand for reformation within the church. Prior to the interruption with Rome, the church was rife with pluralism, barratry ( one of the Catholic Pope? s chief weaknesss ) and breaches of the vows of celibacy. It is hence clear that there were jobs with the English church prior to the interruption, but although it was unpopular, many people including Henry remained Catholic: ? A house Catholic, he was acute to hold apostolic blessing, and the more improbable this became, the more he was forced to oppugn the Pope? s legal power in England? [ 2 ] To carry through a interruption, Henry needed some sort of justification, and he would besides hold to guarantee that in implementing the interruption itself, he was non seen as back uping unorthodoxy and the Protestant reformation in peculiar. We will write a custom essay sample on The Dissolution Of The Manasteries Essay Research or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page With the assistance of adviser Thomas Cromwell, Henry aims to ordain the interruption with Rome utilizing codified authorization ; that of the male monarch, Godheads and parks moving through parliament. ? A sequence of genuinely radical Acts of the Apostless of parliament now cut the bonds? religious, legal, fiscal? which linked the English church and province to Rome? [ 3 ] There were several chief landmarks in the interruption with Rome, the first of which was the act in restraint of entreaties. This was a justification and definition of royal domination, and was grafted by Thomas Cromwell. It was the act of domination in 1534 nevertheless, that would turn out to be Henrys greatest measure frontward in the interruption. It confirmed Henry? s headship of the church and explicitly reserved the Crown the rights to the organizing and jurisdictional powers once held by the Papacy. By this, the Crown would command the right O specify the church? s instructions and doctrinal determinations, finally ensuing in the ruin of the monasteries. As a consequence of Henry? s force per unit area on the English clergy in his efforts to convert the Pope to allow a divorce, the disintegration of the monasteries became an of import and necessary undertaking. By taking the Pope? s most loyal protagonists from England, Henry was badly restricting his power. In 1533, in position of Anne Boleyn? s impending gestation, Thomas Cranmer, an archbishop, declared Henry? s matrimony to Catherine shut-in, ( ? the male monarch must halt life in this wickedness with this adult female who is non his married woman? [ 4 ] ) and married him to Anne Boleyn. ? The Act of Supremacy? so, established Henry as caput of the Church of England, and marked the terminal of the Pope? s influence in his kingdom. Threatened by the Pope with exclusion, if he did non take Catherine back, all hopes of rapprochement with Rome were passed. Henry? s reformation was traveling quickly.When H VIII foremost initiated the disintegration of the Monasteries, he was confronting unfavorable judgment from assorted sides. It must be understood that in make up ones minding the cogency of Henry? s claims for the disintegration, there are two sides to the statement. Protestant supp orters of Henry? s actions, argue that after the 1530? s, all the monasteries were corrupt and a topographic point where evildoers lived in a luxury paid for by others. The grounds for cloistered life they claimed, were based on a prevarication created by the Papacy, to beef up its ain place: In order to decrease the clip a individual spends in purgatory when they die, money must be donated to the church in order to salvage their psyche. As a consequence of these false and morally corrupt claims on behalf of the Papacy, Protestants argued that the monasteries deserved to be dissolved, as the money they survived upon was gained under false pretensions. Another factor that supports Henry? s statement for the disintegration, were the consequences found from the? heroism Ben Sira? . Within this, it was discovered that on norm, one one-fourth of a cloistered houses wealth went to the caput of the house, normally an absentee leader, populating their life as a state gentleman, free signifier duty. Disclosures such as this evidently angered the populace, but whether or non Henry was angered in the same manner, or simply saw these factors as farther support for his claims to fade out the monasteries is problematic. It is true that there was a certain component of corruptness nowadays, with immorality, sexual perversion and homosexual patterns all being admitted to by 100s of monastics. But certainly, all these factors point to a demand for reform instead than disintegration. The above grounds entirely does non show a clear image of the existent state of affairs of the monasteries in England, that is certain. It is now known that merely 10 per centum of the cloistered houses in England were capable to corruptness, and that the bulk followed their cloistered ideals and manner of life unfailingly, greatly supported by the populace, and hence laying waste to Henry? s claims that the monasteries were no longer regarded as topographic points of worship, but of wickedness, animal and detestable. Monasteries by and large functioned good, and there is an air of lip service about these claims, if we consider that Thomas Cromwell himself gained wealth at the monasteries # 8217 ; expense wherever possible. Cromwell accepted assorted? gifts? from the smaller cloistered houses, in return for back uping their entreaties against the new statute law? s, an act which he neither intended to transport out nor brood upon. It is clear so that following his promise to the King to do him and the Crown wealthy and moneymaking one time more, Cromwell decided that the closing of the monasteries was where he would accomplish this proposed wealth. By lawfully shuting the monasteries, this? larceny? would do the King affluent beyond his wildest dreams. If we consider so, that Henry? s motivations were about wholly based on his want for wealth, and without which his proposed disintegration would neer hold taken topographic point, the cogency of his claims is slightly decreased. Henry VIII? s grounds for he disintegration of the monasteries hence, were non at all justified in the manner he had claimed. He sought merely wealth, and it is this desire to derive control and achieve the wealths that came with it which motivated Henry. His greed and the falseness of his many claims against the monasteries succeeds in uncovering his existent wants, and nullifies any old statements based on his spiritual concerns for the disintegration.

Free Essays on Nietzsche

In Nietzsche’s philosophy he made no room for God, let alone religion itself. Nietzsche saw religion, especially Christianity, as a weakness. A Burden put on man to cloud the mind with thoughts of another world in order to justify their meager existence in this one. When used as a tool of education or cultivation, religion could be useful just as politics or economics (Cowan72). The problem arises when religions do not want to be used as a tool for education, â€Å"but insist on having their own sovereign way†. They believe that they are not the means to any kind of end, but rather the end itself. Religion can be an intellectual journey, but it cannot be allowed to become the destination to which we are all struggling to arrive. (Cowan 74). This can only serve to downplay the role of man in the universe, a role that is already dangerously insignificant. In the eyes of Nietzsche Christianity has many sacrifices, these sacrifices are made for someone or something th at only exists in the man- written accounts of the Bible. Nietzsche saw Christianity as an endless cycle of sacrifice. Not by any means sacrifice for the better good, nor for any kind of enlightenment, but rather sacrifice for the pure sake of sacrifice. What good could possibly come of this? I believe he would be quick to answer the question. With the exception of a somewhat Hobbesean premise of being â€Å"one more means for overcoming resistances, for the ability to rule† (Cowan 72) and giving â€Å"some of the ruled the instruction and opportunity to prepare themselves for future ruling and obeying† (Cowan 73), no good can come of this. Nietzsche makes his dislike for Christianity quite evident, and I believe rightly so, for it serves as a lifelong scapegoat for the man who knows worldly failure. This same man who may fail to hold on to employment in the temporal world, for it seems that economic prosperity is anti-Christian, or who can’t ‘turn the other ch... Free Essays on Nietzsche Free Essays on Nietzsche Nietzsche claims that we live in an historical age that is â€Å" beyond good and evil.† We are no longer restricted or limited by moral authorities and hence possess a new freedom and creativity. Citing works we have covered, what is the political promise and danger arising from the teaching that morality is a myth? Does the realization that we are â€Å"beyond good and evil† benefit and fulfill man? Why or Why not? If not, what else is necessary? Finally, given the readings, are you hopeful about the future? Why? Nietzsche believes that no history can be defined and claims that there is no such thing as something that has no history. Through examining Nietzsche it becomes evident that searching for the definition of species is not only futile but also unnecessary. This definition is something that he believes changes over time, without any permanent lasting and stable reality. Unlike Hobbes Nietzsche believed that our value systems are culturally determined, they arise not from conventional folk wisdom. His relationship with the truth has nothing to do with the meaning of a moral system. Humans described by Nietzsche are like human culture and have a history. We have a personal history were we ourselves cannot be defined, we continue to be a constant process of becoming, and or transcending the person we have been into something new. Many might feel that we are defined by some essential quality when in fact we are constantly being defined by other factors. Nietzshe states that humans believ e they must create their own system or become enslaved by another man's system. The lives of the human must be lived in solitude from others, we choose to create our own horizon. In comparison with Marx, he believes that the material forces of production and division of labor control the process of transformation of the individual self and ideas. This is said to be the logic behind the creation of history through Marx. Through the creation of h...

The Benefits and the Drawbacks of Voice over Internet Protocol (VoIP) Telephony - Research Paper Example In simple terms, VoIP can be considered to have similar function like that of telephone but this process has many extended features. The project will broadly analyze the importance of this technology and all those areas where it can be widely implemented and applied. The study will also comprise of the scope of development of this particular technology and the extent to which this technology can be made popular and relied upon. Furthermore, all those broad measures will also be highlighted that can be implemented for making widespread application of the technology. Beside the importance, the problems that will be faced while identifying the measures along with the drawbacks associated with this technology will also be listed and discussed upon. The study will also encompass the various issues related with the security and privacy concern associated with the use of VoIP. Additionally, it will also highlight the other essential features of VoIP reflecting its efficiency in terms of cos t of the technology, accuracy, quality, and timely delivery of services among other factors. THESIS STATEMENT The main aim of the study would be to analyze all those broad factors that can prove to provide opportunities of growth for Voice over Internet Protocol (VOIP) technology. ... VIEW Identifying the Network System Used In the VoIP Telephony According to Hiwasaki, Ohmuro, Mori, Kurihara and Kataoka (2006), a very high tech networking process is followed in the process of VoIP. The networking system allows uninterrupted communication process both in audio and video modes. The network codifies the signals in such a way that all round clarity is maintained in the overall communication process (Hiwasaki, Ohmuro, Mori, Kurihara and Kataoka 1-7). Defining the Importance of VoIP Telephony for the Business World As per Garrie and Wong (2007), there are various factors that can be considered for determining the importance of VoIP telephony for the business world. Accordingly, if the voice that transmits through the networks is regulated properly over the internet protocols then it would be able to create a positive impact in the overall voice process. Furthermore, if the voice is processed and transmitted from one channel to another in a more precise form then it woul d provide great benefits and this efficiency can also be utilized in a business and can prove to derive much better results. It can be strongly admitted that applicability of VoIP telephony is widely gaining popularity in the business segment as an effective modes of communication. It has been ascertained that VoIP telephony offers quick dissemination audio-visual messages relatively at lower costs and at higher speed (Garrie and Wong 550-574). Evaluating the Benefits of VoIP Telephony in the Global Communication Kerner (2005) suggested that the use of VoIP is becoming widespread and is continuously being utilized in the overall market. It has been argued that the application of VoIP can be made even more efficient if more stress is laid upon providing end to end results. It has been

Do the questions below. ( every questions should be more than 200 Term Paper

Do the questions below. ( every questions should be more than 200 words) - Term Paper Example However, it does not mean that labor is the most valuable practice though some historical perspectives give labor such prominence. This occurs in social structures where development of productive forces is minimal so the labor activity completely occupies the individual’s life. This highlights the need to recognize labor as the centre of the ontology of culture (Stanley and Wise 1). This is because additional aspects of human activity entirely depend on the capability of individuals to provide labor within a stipulated time. Additionally, advancement of productive forces determines the capacity of individuals coupled with the extent of complication of social needs that require labor satisfaction. Marx’s expression â€Å"changes his own nature† draws mistranslation, particularly because the word â€Å"nature† can have two interpretations. The first meaning relates to human beings as the subjects of the action; a subject performing an activity needs to alter his or her own nature in a definite way to achieve the stipulated targets. The other meaning of â€Å"nature† relates to environment and emphasizes the alterations of the world because of intentional activity (Stanley and Wise 1). Additionally, humans alter the world to launch their own social objects to change the course of the society. Q: 66. â€Å"Give everyday examples illustrating the contradiction that in everyday practical activity exchange-value is sometimes considered immanent and sometimes considered relative†. Presently, in each practical activity, exchange value may be either immanent or relative. Products attain value because they are expressed in monetary terms. The value form of a product exists after different products have been compared with each other. The value of products is dynamic because it continuously develops based on trading processes (Lendvai 1). Presently, individuals objectify the worth of produced goods to enhance trade. By doing this, t he individuals are evaluating and contrasting the value of their efforts. Additionally, while individuals are comparing and justifying the products’ value before exchange, they are also comparing the intensity of their efforts. Therefore, the worth of a product largely depends on the worth of other products regardless of product evaluation (Lendvai). This depicts that exchange value is at times relative. It is imperative to say that immanence is a notion of relationship. Therefore, exchange value is at times transcendental and exceeds the physical features of objects, implying that values exist above the individual senses (Lendvai 1). An example to illustrate this is that the aesthetic worth of a painting is not similar with the textile of the canvas and the oils within it, though the painting cannot exist without these substances. Additionally, the exchange value of an object like diamond cannot subsist without its physical and chemical reality. Similarly, two portions of wo od fixed with the figure of a cross may enjoy sacramental value. Therefore, these examples clearly show that exchange value can be immanent or relative. Q: 98. â€Å"Take two very different kinds of labor, such as teaching and construction work, and discuss in what respect they are equal†. There exists a relationship between teaching and construction work. Teachers serve as architects of a better future of students because they nurture and monitor their progress, thereby ensuring that these
