...that you obtain by burning Magnesium. We can calculate the empirical formula by combining the masses of magnesium and oxygen. Before combining the Mg with oxygen we will weigh it and we will also weigh the product of the reaction, Magnesium Oxide. If magnesium is heated in open air, its reaction with oxygen is fast. We can slow down the reaction by limiting the supply of oxygen that reaches the magnesium; we do that by putting a cover on the crucible that contains the magnesium sample. magnesium + oxygen → magnesium oxide (a) 2Mg(s) + O2(g)⇒ 2MgO(s) magnesium + nitrogen →...

...| Experiment to find the amount of water in a hydrated compound | Calculating Reacting Quantities and Formulae | | Contents Aim 2 Introduction 2 Hypothesis 3 Apparatus 3 Method 3 Results 4 Calculation 4 Conclusion 5 Evaluation 5 Bibliography 6 Aim The aim of this experiment is to find the number of molecules of water of crystallisation combined with one molecule of magnesium sulphate and to ultimately find the formula of the hydrated salt. Introduction Within crystals of certain salts, there are a fixed number of water molecules, combined chemically in a fixed proportion. When a salt crystallises from a solution, it forms hydrated salts which contain water molecules that are loosely bonded together. The name for this is the water of crystallisation or water of hydration. Magnesium sulphate contains seven molecules of water (H2O) for each formula unit of MgSO4 and can be written like this: - MgSO4.7H2O The dot shows the weak salt/chemical bond in the formula. To determine the formula of a hydrated salt, it must be heated so that the water of crystallisation evaporates. When magnesium sulphate has been heated, the water is removed to form an anhydrous salt. This can be reversed by adding water to the anhydrous salt to make it hydrated which will cause the water to reattach itself to the salt. Other substances that act similarly to hydrates, but have distinct individual characteristics are:- * Hygroscopic – substances...

In fact, it is one of the main issues in the world today, alongside poverty, world hunger, and global warming. Despite this, corruption has given many opportunities to people across the globe. Although corruption is highly looked down upon, it is certain that corruption benefits individuals. The idea of corruption benefiting individuals is clearly seen in Arthur Millers, The Crucible. In the play, the Putnam's are known for their manipulative personalities and corrupted behavior. For example, Mrs. Putnam states “And so I thought to send her to your Tituba...Tituba knows how to speak to the...

...Alexis Wauford Mrs. Hollewell The Crucible 11 May 2017 Importance of Reputations in The Crucible The desire to maintain an upstanding reputation greatly affects characters in The Crucible. During this time period, people were very concerned with their positions in society. They were in a very judgemental community where everyone knew each other, and because of this, people were very worried about how others perceived them. A poor reputation could cost someone their social life and many characters made decisions based upon this. The decisions that the characters made affect not only themselves, but the characters around them. A few examples of characters who worry about their reputation are John Proctor, Abigail Williams, and Reverend...

Danforth and the HUAC B. Danforth and Joseph McCarthy C. Elia Kazan and Abigail Williams VII. The conclusion The Connection The Crucible written by Arthur Miller has a symbolic meaning. It is an allegory, “a story in which people, things, and events have a symbolic meaning, often instructive.” (Agnes 17). The setting, the Salem witch trials of the 1600’s is similar to the McCarthy trials of the 1950’s. The people, the events, the details relate to one another. Miller purposely wrote his story to instruct the fact that the mentality of the people in the 1950’s was no different than the mentality of people in the 1600’s. In the 1600’s people followed a strict religion known as puritanism. The Puritans believed they were sent by God to purify the world of sin and evil. Because of this they believed they were superior to others. Consequently, when they did sin, they tended to feel guilty and blame others for their faults. This blame and guilt led to one of the most fearful times in America. The Salem witch trials happened during the 1600’s and at a time where everyone...

...Campus Crucible Campus Crucible is an R&D company that purchases inventions from campus-based researchers and companies who do not have the means or desire to further to develop them. Campus recruits its own scientific or engineering teams to develop the inventions for commercial use, and then sells or licences them to other companies. It is currently in negotiations to buy a new invention that could significantly reduce the energy consumption of traffic lights. The invention seems to be more promising than existing technologies aimed at doing the same thing, and if Campus can buy the invention and succeed in developing it, they could make a profit. Based on what Campus knows about the invention, it is 50% likely to have commercial potential (i.e. to be better than currently available competing technologies) and 50% likely to have no potential. The inventor is willing to sell it for €2 million. It will cost Campus a further €0.5 million to explore the commercial potential and then, if it does have potential, a further €1 million to develop the invention before selling it. If it has commercial potential they will be able to sell or licence it for €7.5 million. If the invention has no commercial potential, Campus will not be able to sell it at all but will only incur the purchase cost and the €0.5 million exploration costs, and not the €1m development costs. However, Campus could conduct preliminary testing on the invention before buying it, to get a better indication...

This essay is going to compare how the titles The Narrative Life of Frederick Douglass , an American Slave and The Crucible can relate to violence on how it is described in How to Read Literature Like a Professor. In How to Read Literature Like a Professor, by Thomas E. Foster, he explains how violence has a variety of ways to be expressed as well as many meanings to be understood. He states , “ It can be symbolic, thematic, biblical, Shakespearean, Romantic, allegorical, transcendent.” These describe in literature why violence is a key part of the story. Violence in literature always has a meaning never usually you will find it meaningless. Foster states , “Violence in literature, though, while it is literal, is...

...Nancy Barry Case Analysis Jason Mandel Ramapo College of New Jersey 21st Century Leadership October 15, 2015 Briefly introduce the case (discuss Barry’s important life decision) The Nancy Barry chapter in “The Leadership Moment” is the story of a Harvard-educated woman who quickly gained success as a high-powered lending executive at the World Bank, and then went on to transform the business world as President of Women’s World Banking (WWB) (Useem, 1998). As readers, we are exposed to Nancy’s important life decision early on in the chapter when the WWB approaches her to lead their organization (Useem, 1998). At that time, Nancy was a highly compensated executive as Chief of the World Bank’s Industrial Development Division, with a large administrative support staff, and had been working there from 1975-1990. Clearly, giving up a powerful position with the globe’s most prominent bank after 15 years of service could not have been an easy decision. However, Nancy fully supported the WWB and the Grameen Bank of Bangeldesh for quite some time, so even with her contemporaries calling her “crazy” for leaving the World Bank, Nancy proved she was authentic by taking the position as President of WWB and following her heart instead of her wallet. Discuss Nancy Barry’s leadership style using LMX theory The LMX theory, or leader-member exchange theory, spotlights positive, dyadic relationships between supervisors and subordinates, often producing an increase in organizational efficacy...

...Laboratory Activity 1 DIFFERENCES BETWEEN ORGANIC AND INORGANIC COMPOUNDS Compounds that consist of carbon atoms and their molecules are known as organic compounds. This is the reason why Organic Chemistry is basically defined as the study of compounds of carbon. The electronic structure of the carbon atom shows that it has four valence electrons or electrons that are capable of forming chemical bonds. An atom, to be stable, must have four pairs of valence electrons or a total of eight electrons at its outermost energy level. There are two ways by which atoms can complete this configuration in the outermost energy level: 1. An atom may share electrons with other atoms so that with the shared electrons it acquires a complete outermost shell. The chemical bond formed is called a covalent bond. 2. An atom may lose or gain enough electrons to acquire stability of configuration. In the process, one atom becomes positively charged and the other negatively charged. These charged atoms are called ions. Therefore the chemical bond formed is known as ionic bond, a very strong chemical bond. Most organic compounds are covalent compounds. They are weaker or they easily yield to chemical reactions, e.g. combustion, and substitution. They have higher melting points compared with most inorganic compounds. They decompose and produce charcoal at moderate temperatures. Due to the nature of their chemical bonds, few ionize in water, therefore most organic compounds...

...Leading in a Dynamic Era In examining leaders it is apparent that successful leaders, particularly when leading through difficult times need to be able to transform and drive change through creative and innovative approaches, in a way that inspires and transforms both the people and therefore the organisation (Johnson, 2009). Conant is an example of a transformational leader who used a people centred approach to turn around the Campbell’s Soup company. In 2001 Campbell’s share price had dropped by 50% in three years (Gerdeman, 2013). Sales of canned soup had declined in a highly competitive market and 62% of its managers considered themselves not actively engaged in their jobs (Waghorn, 2009). However, By 2010, Campbell’s total shareholder return, at 68% was nearly 5 times the return of the S&P 500 and employee active engagement levels soared to 62%, which is an engagement ratio of 23:1. Gallup Organisation considers 12:1 to be ‘world class’ (Waghorn, 2009). How did Conant achieve this? No one leadership strategy can transform a business this close to failure. For Campbell’s it took a combination of cost control, innovation, a change in marketing direction and especially, a concerted effort to invigorate the workforce and change its culture (Waghorn, 2009). Conant believes that of all the measurable elements in building culture, engagement correlates most closely to shareholder returns. Conant’s people focussed strategy states that “to win in the market place…you...
