Which two metals combined together give the higher voltage when reacting with acid :: GCSE Chemistry Coursework Investigation

Which two metals combined together give the higher voltage when reacting with acid Introduction In this investigation we will find out which two metals combined together give the higher voltage when reacting with acid. The metals used will be:  · Aluminium  · Zinc  · Iron  · Tin  · Lead  · Nickel  · Copper To make a prediction on what metals will be the ones that give the highest voltage when combined together you need to find out if the position in which the metals are at in the reactivity series would make a difference, and if it does, how? You also need to find out how the metals react with acids. We know that the higher the metal is in the reactivity series, the stronger it will react with an acid. Theory Batteries have chemicals inside to store energy. When two different metals that are connected by a wire are placed into an acid, a potential difference (voltage) is produced. This occurs because the metals react with the acid forming Hydrogen acid, a metal salt solution and an electric charge. The charge flows from the most reactive metal to the least reactive metal. Equipment The equipment used will be:  · Acids  · Metals  · Wires  · Voltmeters  · Beakers  · Measuring cylinders  · Stop watches  · Sandpaper Method Collect all the equipment and place it as it is shown on the diagram above. Choose around 10 pairs of metals and place one pair in the beaker, and connect them both with a wire. Put them in for a few seconds, and voltage will be produced when the two metals react with the acid forming hydrogen, a metal salt solution and an electric charge. This charge will flow from the least reactive metal to the most reactive metal. Measure the voltage with the voltmeter and write it down. Do this for every pair of metal you have chosen, and then find out which ones are the most reactive and which ones are the least. Prediction I predict that the highest metal in the reactivity series and the lowest metal in the reactivity series from the metals we are using will produce the highest voltage. I think this because voltage is also called potential difference, so this shows that there is more power when the difference between the metals is larger. This means that the voltage in the metal which is lower in the reactivity series must have a higher voltage to the metal that is most reactive to make my prediction correct. I think that the highest the difference = the higher the voltage. I also predict that changing the acid will change the ending result. I think that the stronger the acid, the higher the voltage.

Haitian Culture: Impact on Nursing Care Essays -- essays research pape

Haitian Culture: Impact on Nursing Care   Ã‚  Ã‚  Ã‚  Ã‚  The Republic of Haiti is in the western part of the island of Hispaniola in the West Indies. It is densely populated and has the lowest per capita income in the western hemisphere (Kemp, 2001). The population of more than seven million is made up of mostly descendents of African slaves brought to the West Indies by French colonists. The horrible conditions in Haiti, such as crushing poverty, unemployment and illiteracy, and high rates of acute and chronic illnesses and child and infant mortality, result in the illegal immigration of many Haitians to the United States, France, and other countries in Western Europe. Most immigrants are adults and teens who leave Haiti in tiny boats, despite the risk of drowning and other hazards. According to Pan American Health Organization (PAHO) 2001 statistics, the number of refugees has declined to several thousand per year since the early 1990’s.   Ã‚  Ã‚  Ã‚  Ã‚  Nearly all Haitian immigrants entering the U.S. are poorly educated, illiterate, and speak only Creole, which is seldom seen in written form. Creole is a â€Å"pidgin† language, meaning it is a simplified form of a base language with parts of other languages added. These types of languages were frequently used by sailors, pirates, and other trade people to accommodate the span of communication needs they faced. Haitian Creole is thought to have been derived by combining various native African dialects with the French language of their owners. Very few Haitians (10%) can actually speak French, and one’s ability to do so is seen as an indicator of social class. Because of Haitian views that Creole is the language used by the poor and uneducated, many will claim to be able to speak French and become insulted if it is suggested that they speak Creole. This can pose a problem for the healthcare worker trying to find a way to communicate. Often the only in terpreters available to a family are their children who have learned English in schools here. This can create conflict within the family therefore a facility provided interpreter usually produces a better outcome. Written materials are often of no use to the Haitian immigrant.   Ã‚  Ã‚  Ã‚  Ã‚  Socioeconomic status plays a huge part in how Haitians identify themselves, and influences their actions greatly. Many Haitians wil... ...of exercise. These factors all contribute to the young life expectancy of about 49 years (World Health Organization, 2001). When caring for a client of Haitian descent, it is important to be mindful of language and education level, religious and cultural beliefs, and traditional health maintenance practices that may be incompatible with modern medicine. The healthcare provider should respect these cultural differences and be accommodating whenever possible to promote the spiritual and physical well-being of the client. References Ackerman, L.J.

Pales Paradigm and Lamarcks Paradigm Essay -- Philosophy, Scientific

According to Tomas Kuhn, â€Å"normal science means research firmly based upon one or more past scientific achievements, achievements that some particular scientific community acknowledges for a time as supplying the foundation for its further practice† (Pajares ). The achievements that Kuhn defines as paradigms help the scientific community develop a scientific method to resolve puzzles. Particular puzzles that paradigms fail to solve and eventually lead to paradigm shifts are called anomalies. Since Kuhn first introduces the relations of these three terms to philosophy of science in â€Å"The Structure of Scientific Revolutions,† scientific communities have improved their understandings of science and society. By describing two different paradigms of Paley and Lamarck on organic change in the early nineteenth century, Kuhn’s paradigms can further demonstrate its efficient way to articulate scientific assumptions and understand the scientific change. In William Paley’s paradigm, the world is perfectly designed by a benevolent God who purposefully created everything and â€Å"superadded pleasure to animal sensations† (RP 47 ). Paley strongly believes the existence of a God who is wise and benevolent enough to create everything on earth with happiness and a purpose. For Paley, science is a tool to complement the greatness of religion and prove the importance of Design (RP 46). In order to support his paradigm, Paley illustrates the contrivance and work of God in nature with the methodological assumption of First Cause (the belief in the existence of God) and Final Cause (the belief that a God creates an object with a purpose). Additionally, the metaphysical assumption of a close, active God underlies the paradigm as a premise that influences e... ...d for centuries. On the other hand, Lamarck challenges this traditional thought and brings about a new theory that contains controversial ideas. With this provocative attitude, he demonstrates his intent to challenge the achievements for centuries and cause scientific change leading to paradigm shifts. Comparing Paley’s and Lamarck’s paradigms show how Kuhn’s paradigm can be used to compare and explain different paradigms. With the examples of observation, assumptions, and anomalies, two paradigms clearly demonstrate their ability to solve puzzles as well as their potential influence on understanding of society. The Kuhn’s paradigm model helps understand the changes in scientific perspectives and the course of European society. The use of this paradigm model can provide an opportunity to explain current scientific paradigms and assist in developing new paradigms.

Sentences and Proposition

â€Å"Sentences, originally, is a term of grammar and linguistic. It's introduction into logic is a recent innovation and it still seems strange to many to find the word sentences where propositions might have been expected. â€Å"(Alonzo) Basically, propositions have been taken to be sentences that can be true or false but can never be both. This shows that sentences when they meet some conditions will become a proposition. One major distinction between sentences and propositions is that, a sentence cannot be a bearer of truth value while the proposition does so. This is because propositions have logical connections which enable us to deduce whether it is true or false. Sentences in the kinds of questions, exclamations and the like can not be taken as propositions. Example; What is your name? We can not tell whether this is a true or false sentence. A sentence(proposition) will convey truth when it expresses a proposition, that is, when a sentence has a reference and it is meaningful. The presence of the reference in a proposition will enable us to connect it with our ideas or beliefs outside our mind in order to ascertain their truth value. This differ from a sentence which may not have a reference , example, keep quiet! In a proposition like, PHIL 402 students went to Cape Coast last thursday,it is clear what the reference is and with the meaning of the proposition, you can tell whether it is a true assertion or a false one. Thus, propositions and sentences, they have been used interchangeably, but for the philosophers, they are different terms referring to different things. Simply, a sentence that has a reference and is meaningful expresses a proposition.

Zeitoun Analysis

Marcellus Lopez Mr. Buckley Honors American Literature September 20, 2011 Abdulrahman Zeitoun, Not Clark Kent Zeitoun, a fantastic novel by author Dave Eggers is a heroic tale of faith and courage set during Hurricane Katrina of August 2005, in New Orleans, Louisiana. The hardy protagonist of the chronicle is Abdulrahman Zeitoun, a Syrian man, living in Louisiana with his wife, Kathy, and his three daughters and stepson. Zeitoun, a former sailor, used to storms and seas, at the time of the hurricane owned a contracting business, building, repairing, and painting.Zeitoun's heroism and bravery have made very clear to me that being a hero is †¦ well, really damned stupid. If not that, then at the very least, being a hero is inadvisable and unwise. Zeitoun went far out of his way to help others in a whirlwind of charity and self-assurance. In doing so, he caused great damage to himself and those closest to him. Zeitoun went above and beyond what was asked of him to assist members of his community, ignoring the one thing asked of him by his worried wife, who demanded he evacuate with her and the family.Just as he had gotten into the momentum of routinely feeding some dogs abandoned by their owners daily, Zeitoun was arrested under false charges, rendering him unable to contact Kathy. His absence left his family distressed and disoriented. Kathy panicked hour by hour, praying to hear from her husband, with no such luck until much later. While Abdulrahman was missing, his family overseas was just as worried about him. His brother would call Kathy, personally urged to bend the truth about her husband's whereabouts. While Zeitoun was imprisoned, his family scrambled to get but a word from, him, not to mention the dogs died.I would stop and think at times in the story, does Zeitoun take the time to assess whether the possible consequences are worth the good he is trying to do? His time in prison shows him reflecting on the good he'd done, as well as praying for a be tter situation, but I do not recall one time at which he says to himself that he definitely should have left New Orleans. Did he not expect at all that in all the paranoia of a critical hurricane in a post-9/11 society that a Middle Eastern Muslim man would be a target for bigotry and used as a scapegoat?Although, his imprisonment was completely unwarranted, along with the charges brought against him and accusations made against him, nothing should have been a surprise to Zeitoun. Zeitoun was either unequipped with the knowledge that this country's ideals of justice are far from perfect and that the executive branch of our government is very prone to quick, harsh decisions and quick, definitive judgments†¦ or just not very thoughtful. The results of Zeitoun's poor decision to stay in New Orleans stuck to Kathy for the rest of what we read of her life in Zeitoun.Kathy's mental healthy was sacrificed all because Zeitoun foolishly remained in the city, with knowledge that a partic ularly dangerous storm was approaching. By the end of the story, I couldn't help but notice how much Abdulrahman's â€Å"courage† and â€Å"faith† resemble naivete. He stayed in New Orleans to ride out Katrina because he was obstinate and over-confident. It's fair to say that having been a sailor, he was rugged enough to handle a hurricane, but with a family and the understanding that many other people get mixed up in the spiraling torrent of a natural disaster, it is also fair to say that he could not have been prepared enough.Zeitoun tells that he felt called by God to help people in the storm, but this, I deduce, was no more than a rush he felt from completing a successful rescue. Everyone wants to be a hero. The sensation of doing good for others does more good for the good-doer than should be done. One of my favorite lyrics says, â€Å"When you help others, you can't help helping yourself. † For a man to be so complacent with an unpredictable force of natur e that he would be willing to let it come and see what happens is indubitably foolish.Abdulrahman refusing to evacuate with his wife very closely resembles a child on a playground, shouting to his mother, â€Å"No, Mommy! I don't wanna go! † Zeitoun, an informative novel by author Dave Eggers is a tale about how faith and â€Å"courage† can really screw things up. The foolhardy protagonist of the chronicle, Abdulrahman Zeitoun, shows us how being over-confident and letting ourselves become too comfortable can lastingly repercuss on the lives of our wife and family. Zeitoun's over-confidence and naivete have made it absolutely clear that trying to be a hero is really damned stupid.

Art and Function in a T-Shirt Essay

Defining and evaluating artistic and aesthetic value has often been a problematic task. This is because aesthetic judgements are subjective and are influenced by prevailing cultural, economic, political, and social norms. Hence, the definition of art remains a contested domain between those who believe in â€Å"high art† and the advocates of artistic and cultural relativism. (Danto 35) The difficulty in ascribing aesthetic value to objects is evident in the fact that relativism, with its focus on the individual subjective experience, would render anything and everything as artforms since humans ultimately attach meanings to objects they possess. Changes in culture and socio-economic conditions also alter and influence the very standards by which the aesthetic value of art forms and other objects are judged. For instance, in judging a t-shirt with Bob Marley’s face printed on it on the front through the use of the silkscreen method, one easily dismisses it as a non-art when judged according to the traditional notions of fine art. This is because the t-shirt and the print on it do not express artistic creativity, which is a prerequisite for objects to be considered art forms. The t-shirt and the print, which can be replicated many times over by any one with knowledge on silk screen printing, do not possess relevant canonic properties of art such as unity, complexity, and intensity which could evoke intense human experiences and therefore, aesthetic appreciation (Goldman 185). The sight of the t-shirt does not stir up feelings of beauty nor does its fabric hold anything extraordinary for the senses. The print on the t-shirt does not convey a particular style to capture attention or cause pain or pleasure, at least not in the way that beholding Picasso’s paintings evoke wonder, mystery, and other psychological sentiments arising purely from the painter’s use of style, colors, and the imagination. Likewise, the t-shirt with the print on it was created not for the purpose of being admired as an art. As such, the t-shirt is not valuable in itself but gains value for its function to humans, contrary to traditional visual and other forms of art. Art forms are valued for their artistic worth or for their ability to command a definite blending of particular perceptual and sensory elements from the audience (Goldman 188). On the other hand, subjecting the t-shirt to evaluation based on the principles of aesthetic value leads to interesting results. The t-shirt with Bob Marley’s face printed on it clearly fulfills two aesthetic principles. First, the t-shirt becomes a medium for the image of Bob Marley, a cultural icon in reggae music and in the historical struggle of Jamaicans. In this case, the t-shirt with Bob Marley’s image transcends its status as an object worn by humans to cover themselves and becomes an expression of the values of reggae and Jamaican culture in a manner similar to cultural artifacts. Second, the t-shirt itself may be valued by an individual for the sentiments attached to the shirt. It could have been given as a gift for an occasion or has been worn to events associated with feelings of happiness which make the t-shirt valuable to the individual because of the memories of joyous times spent while wearing it. Thus, other people might consider the same t-shirt aesthetically valuable. Fenner observes that objects do not have intrinsic aesthetic value; rather it is the subjective experience of humans that create aesthetic value for objects, particularly the expectation of pleasure from an object (122). Those who appreciate and know Bob Marley may value his image on the t-shirt and subsequently feel pleasure or the elevation of other feelings associated with Bob Marley’s musical contribution and historical roots. As such, the t-shirt may be appreciated by people who share a cultural affinity with Jamaica or of the counterculture that Bob Marley represents. The value of Bob Marley’s silkscreened image extends to the t-shirt which carries it and reinforces the value of the shirt for its owner. The t-shirt, donned by the owner, can therefore be considered the medium for the expression of individuality and creativity of the wearer. Wearing Bob Marley may be a political or cultural statement for a particular culture, particularly as a representation of the struggle against apartheid or against conventional popular music and the culture it represents. Hence, the appreciation of Jamaican culture or reggae music becomes another definitive aspect of the aesthetic experience that may be separate from the experiences attached to the t-shirt as an object. Likewise, neither the fact that the t-shirt was not created for the sake of art nor its low economic worth prevents it from being categorized as an art form. Fenner notes that the presence of traditional aesthetic properties do not necessarily lead to an aesthetic experience or to the creation of an aesthetic value (121). Hence, the audience can view a pricey painting without feeling any connection with it which would make the painting worthless in terms of evoking a subjective experience of appreciation for creativity or imagination. On the other hand, the same audience may behold the image on a shirt and feel an instant connection, a feeling of intense emotions from memories or meanings attached to the object of attention. It is clear that the traditional definitions of art and the accompanying distinction and stratification between â€Å"high art† and â€Å"lowbrow art† has slowly been eroded with the rise of cultural relativism and postmodern theory. Doubtless, the rigid formality of art has come under attack even within various artists’ circles itself that ascribe to the fluidity and less structured styles of postmodern culture. Thus, even an ordinary t-shirt can now be considered an art form when, after critical analysis, it is able to fulfill the principles of aesthetic value. Works Cited: Fenner, David E.W.

Faith Statement

Faith Statement My faith has grown immensely over the years. Throughout my faith journey everyone at the church and in my family has influenced my life in faith. To me when you are baptized it means your parents are making you a child of God but when you get confirmed you are accepting your baptism and becoming a member of the church. Jesus is a big part of mine and everyone’s life because he died on the cross to save our sins.We pretty much all take advantage of Jesus’s love. Everyone makes mistakes, some foolish, but still Jesus will always forgive us and love us. Also, even though I know I will be forgiven, church has taught me that we should all try to do our best at doing what God wants us to do and the right thing. Since I’m a Christian, whenever I am about to do something that I think God wouldn’t want me to I think it over and try to make the best choice.I think that Holy Communion affects my life by making me feel clean and saved. Prayer is very v ital to me. Going to church has taught me that if I pray to God for help in something most of the time he delivers but when he doesn’t it’s not because he isn’t listening but simply because it’s not meant to be. Throughout the years, I have learned to help God and serve around the community. After I get confirmed I will still attend church and do service projects to help others.
