Analysis - Essay Example This environment exposes him to the knowledge of the scientists living within it. For example, Victor gains his knowledge of natural philosophy, â€Å"I chanced to find a volume of the works of Cornelius Agrippa. I opened it with apathy; the theory which he attempts to demonstrate and the wonderful facts which he relates soon changed this feeling into enthusiasm† (36).   Victor becomes fascinated by natural philosophy as described by the author, and thus desires to experiment with what the author says. This eventually leads Victor to create The Monster, causing Victor to have a miserable life. Also, because Victor believes that the knowledge he has gained can enable him to create the living thing that can be able to lead life just as human beings. When Victor meets with two professors, Krempe and Waldman, he learns from these two professors. He realizes that the knowledge he has is not sufficient to carry out his experiments. Professor Krempe scolds Victor for what he has studied: ‘Have you,’ he said, ‘really spent your time in studying such nonsense?’ (43). From here, it can be noted that Professor Waldman supports him, â€Å"‘I should advise you to apply to every branch of natural philosophy, including mathematics’† (46). With Professor Waldman’s support, he is able to pursue his desire to understand natural philosophy and continues to study it. He does not give up with his passion of creating a kind of a human being; it thus leads him to the creation of The Monster. In as much as sciences environment it affects Victor’s knowledge, his Monster also is greatly changed based on his surroundings. The Monster created by Victor Frankenstein show readers how he is shaped by the conditions surrounding him. For instance, The Monster learns about the world and nature from what he faces after his birth, â€Å"I saw, felt, heard, and smelt at the same time; and it was, indeed, a long time before I learned to distinguish between the

Determining the position of unknown element X in the Reactivity Series Essay Example for Free

Determining the position of unknown element X in the Reactivity Series Essay To determine the position of Element X in the reactivity series Hypothesis The reactivity series is the arrangement of elements according to their reactivity. The most reactive element is placed at the top and the least reactive at the bottom. The elements at the top can displace elements below them from their compounds In the experiment, element X will either have elements more reactive or less reactive or both. Based on this, the position of the unknown element can be found out. Assuming that the element given is not potassium, then potassium will displace X from its compound; thus we can say that potassium is more reactive than X; and X is below potassium in the reactivity series. Assuming that copper is less reactive than X; X will displace copper from its compound. This means that X is higher than copper in the reactivity series than copper. In the experiment, the enthalpy (temperature) change will also show how reactive element X is. For example if X is right above Zinc in the reactivity series i.e. element X is aluminium, then the temperature difference between reacting Al with CuSO4 will be more than reacting Al with ZnSO4 or FeSO4. This is because as the distance (number of elements in between between) the elements increases there is more difference in the reactivity level of the selected elements. When ?H (?Heat) is +ve, the reaction taking place is exothermic and when ?H is -ve, the reaction will be endothermic. When the number of element between the elements reacting is more, then ?H of the reaction will also be more. For example if we take Zinc as element X, then Zinc is more reactive than Lead; but Zinc is even more reactive than Copper. This is because Copper is further below Lead in the reactivity series. Thus a reaction between Zinc and a Copper compound will be more reactive ( will have a higher ?H) than a reaction between Zinc and Lead. When ?E (?Energy) is +ve, the reaction taking place is endothermic and when ?E is -ve, the reaction will be exothermic. The reason behind the nature of ?H stated previously is the ?E (?Energy) of the reaction. Again; more the number of elements between the reactants (according to the Reactivity Series) the lower the value of ?E i.e. more exothermic the reaction is. This is due to the type of bonds present in various compounds. Taking the pervious example, a reaction between Zinc a Copper compound will give a lower ?E than a reaction between Zinc a Lead compound. Thus such reactions are more apparent. Variables Independent The Metal Compound used to react with Element X The metal compound used to react with Element X was varied as this variation of the metal will help us determine the position of element X. Dependent Whether a reaction takes place or not When different metal compounds are used, it is not necessary that a reaction takes place every time. The occurrence of a reaction depends on the metal present in the compound used. Energy Change (?E) ?E depends on the compound used. In different compounds there are different types of bonds present and also every bond has a different energy level. Enthalpy Change (?H) ?H depends on ?E. If ?E is -ve, then the reaction is exothermic; if ?E is +ve, then the reaction will be endothermic. Controlled Volume of the Metal Compound taken The volume of the metal compound taken must be kept constant as varying volumes can affect the final temperature. Size of Element X strip The size of the strip of Element X must also be kept constant as varying lengths can again affect the final temperature. Apparatus 1 Strip of Element X 7 Test tubes 5ml of CuSO4 5ml of FeSO4 5ml of MgSO4 5ml of PbNO3 5ml of KSO4 5ml of AgNO3 5ml of ZnSO4 Procedure 1. Take a strip of Element X and cut it into 7 equal pieces 2. Pour 5ml of CuSO4 into a test tube 3. Put a thermometer into one test CuSO4 and measure the temperature 4. Now put a piece of Element X into the test tube and measure ?H 5. Repeat Steps 3 4 for FeSO4; MgSO4; PbNO3; KSO4; AgNO3 ZnSO4 Diagrams Results Compound Reaction Initial Temperature (à ¯Ã‚ ¿Ã‚ ½C) Final Temperature (à ¯Ã‚ ¿Ã‚ ½C) ?H (à ¯Ã‚ ¿Ã‚ ½C) KSO4 No 21 21 0à ¯Ã‚ ¿Ã‚ ½ MgSO4 No 21 21 0à ¯Ã‚ ¿Ã‚ ½ ZnSO4 No 22 22 0à ¯Ã‚ ¿Ã‚ ½ FeSO4 No 21 21 0à ¯Ã‚ ¿Ã‚ ½ PbNO3 Yes 21 22 2à ¯Ã‚ ¿Ã‚ ½ CuSO4 Yes 22 25 3à ¯Ã‚ ¿Ã‚ ½ AgNO3 Yes 21 26 5à ¯Ã‚ ¿Ã‚ ½ Graph Discussion The strip of element X given to us was shiny, this indicates that element X is not very reactive. Reactive metals such as aluminium usually form a metal oxide layer on top of them thus losing their luster. When Element X was put in sulphate of potassium (which is a clear solution), the solution remained clear, and the piece of Element X also remained shiny; thus indicating no reaction. Element X behaved similarly for sulphates of Magnesium, Zinc Iron. A piece of Element X into PbNO3, after a lot of time, the solution started to become cloudy (white precipitate), indicating a reaction. In this reaction the ?H was +1à ¯Ã‚ ¿Ã‚ ½C. In CuSO4, the piece of Element X was deposited with black precipitate all over. Also the solution becomes lighter blue as compared to the pure CuSO4(aq). It was a very slow process. In AgNO3, the solution turned cloudy (black) immediately after suspending the piece of Element X. If we observe the table below carefully, we notice that Element X did not react with K, Mg, Zn and Fe. But it reacted with Pb, Cu Ag. This means that element X is Sn; because the reactivity series goes as follows: K, Na, Ca, Mg, Al, Zn, Fe, Sn, Pb, Cu, Ag, Au. Compound Chemical Equation Energy Equation ?E KSO4(aq) MgSO4(aq) ZnSO4(aq) FeSO4(aq) Pb(NO3)2(aq) CuSO4(aq) AgNO3(aq) As I stated in my hypothesis, that the further apart the elements are (in the Reactivity Series) the lower the ?E is. This means that the reactions are more apparent (vigorous) and also more heat is produced in such reactions. Conclusion From this experiment, I conclude that the Element X given to me is below Iron and above Lead in the reactivity series i.e. the element is Tin. I also conclude that the further apart the elements are (in the Reactivity Series) the higher the ?H and lower the ?E. I also conclude that such reactions are more reactive (apparent) as compared to those between element with a lower number of elements between them. Evaluation In this experiment, if the mass of element X would have been measured and then used for reactions the reactions would have been more accurate and reliable.

Natural Family Planning :: essays research papers fc

The Natural Failure of Planning   Ã‚  Ã‚  Ã‚  Ã‚  Are modern forms of contraception naturally and morally wrong? Pope Paul VI and his Humanae Vitae declare that technological methods of birth control are immoral and should not be practiced by Catholics. However, as our modern society illustrates everyday, this opinion is inappropriate for not only the faithful of the Roman Catholic Church, but also for non-Catholics. According to Munich Archbishop Cardinal Julius Doepfner, â€Å"Contraception is not intrinsically evil† (The Politics of Sex and Religion). There is a fine line the Catholic church draws between â€Å"natural† methods of family planning and the â€Å"immoral† methods of modern technology. After close review of Catholic doctrines, it is clear that this line does not exist. The intentions behind the actions are what matters. Therefore the encyclical of Paul VI , while maintaining good intentions, cannot give Catholics and non-Catholics alike complete guidance in complete humanness when it comes to contraception.   Ã‚  Ã‚  Ã‚  Ã‚  The major problem for the married believers in the Catholic faith is that Human Vitae neglects their ability to make moral decisions. Paul VI claims that contraception limits a person’s human totality and integrity. However, the reality is that the Church is limiting this principle of human existence by assuming the common man is incapable of making the correct moral choice. For example Paul VI states , â€Å"†¦how wide and easy a road would thus be opened up towards conjugal infidelity and the general lowering of morality.† (Human Vitae 8). It is absurd to believe that all moral problems in our society can be attributed to the introduction of birth control methods. Man, in his complete integrity and totality, is capable of judging moral from immoral regardless of the technological devices he is surrounded by. If all parts of a human are in harmony, means of contraception cannot invade this person’s complete humanness.   Ã‚  Ã‚  Ã‚  Ã‚  Scientific research shows that almost all practicing Catholics today believe that modern means of contraception does not interfere with their beliefs and morals. According to one study, â€Å"Even among married Catholic women who attend church every week, less than 4% use church-approved family planning methods-about the same as the total population.† (Catholics for Contraception). This illustrates the fact that people of faith have made their own interpretations of God’s desires and find no difference between natural family planning and modern methods of contraception. Weekly patrons of the church know the moral teachings of the Church and the consequences, yet the facts show that all believers have not come to a consensus.

Good morning/afternoon everybody. Today, I am here to discuss the overall wealth of America, in hopes to better justify our economy. It is to my understanding that as of this moment, the United States and its economy stands fairly well, increasing total tax revenue by 13%, from $2,482.241 (two trillion four hundred eighty two billion) in 2012, to $2,806.386 in 2013. In addition, we were able to decrease our budget deficit by an additional 27%, with a final deficit standing at $811.851. Although our standings are settled at a decent position, there are ways we could execute even greater; and that is through the improvement of health and human services, the return of our nation’s military from the Middle East, education, alternative energy, and the regulation of taxes. One of the major focuses of our proposal is the improvement of health and human services. Prior to my election, there has been concern about this department due to the recent government shutdown. From October 1 through October 16, the United States entered this shutdown, and reduced most routine operations after Congress failed to enact funds for the fiscal year 2014. The principal factor to this shutdown was The Patient Protection and Affordable Care Act, otherwise known as Obamacare. What this law required was for all Americans to have health insurance—regardless if they truly need it or not—so the total costs towards Medicare and Medicaid spending would decrease. However, it is not worth disrupting government funding to undercut healthcare costs. Congress has one key duty in the Constitution, and that is to pass spending bills that fund the government. With no compromise, our government may experience another one of these disastrous events. To fix this predicament.. . ...ity that continues to be a problem is the amount of alcohol and cigarette users here in the states. The adverse health affects from alcohol consumption accounts for an estimate of 75,000 deaths, while cigarette smoking accounts for an estimate of 443,000 deaths each year in the United States. To promote a healthier lifestyle, in addition to internalizing the externality, we will be placing a $0.10 tax on alcohol and a $0.50 tax on cigarettes, in hopes to reduce demand and utilization. However, if alcohol and cigarette users continue to be unresponsive to the change in price, consumers would still continue to purchase these products, and it would eventually benefit the government in terms of raising money with minimum waste, for it would raise revenue with minimal distortion. In other words, as a result of this tax raise, we will be increasing revenue $5.323 billion.

Candide, The Divine Comedy, Tartuffe, Othello essays

Candide, The Divine Comedy, Tartuffe, Othello essays Voltaires Candide can be easily considered one of the most potent satires of all times, as it is directed not to a particular aspect of the world but to the world as a whole and to the entire human race. What Voltaire mocks is not so much the state in which the world and humanity are in, but the inveterate optimism that characterized the Age of Reason. The values and creeds of the Enlightenment philosophers are demolished one by one in Voltaires work: the famous statement maintained by Leibniz and Rousseau that our world is the best of all possible worlds, the belief that the universe is in a state of unshakable harmony that only gives the impression of chaos, the general optimism that regarded even the dreariest events in the world as good, the faith in the human reason and the free will of man and so on. To remonstrate against what he felt was just hypocritical optimism, Voltaire makes the eponymous character of his work, Candide (who is, not by accident and as his name indicates, incredibly naive and simple) experience, through his journeys and adventures, the entire range of human sufferance: wars, natural disasters, maladies, slavery, religious persecution, rape and so on. In his way, Candide experiences all there is to experience and meets with all the evil in the world. His companions represent three different philosophical attitudes that influence Candides evolution. His gullible nature disposes him to believe the more comfortable theory, which is that of his master Pangloss. Pangloss is thus the prototype of the Enlightenment thinker, the professed optimist who believes in the absolute perfection of the world. Despite of the disasters he meets with and despite of the evil nature of the men he encounters, Pangloss remains a stubborn optimist, an advocate of the perfect harmony of the universe: Master Pangloss taught the metaphysico-theologo-cosmolo-nigology. He could prove to admiration that ...
