Find a Reactions Final Temperature With Specific Heat

Find a Reaction's Final Temperature With Specific Heat This example problem demonstrates how to calculate the final temperature of a substance when given the amount of energy used, the mass and initial temperature. Problem 300 grams of ethanol at 10  °C is heated with 14640 Joules of energy. What is the final temperature of the ethanol? Useful Information: The specific heat of ethanol is 2.44 J/g ·Ã‚ °C. Solution Use the formula q mcΔT Where q Heat Energym Massc Specific HeatΔT Change in temperature. 14640 J (300 g)(2.44 J/g ·Ã‚ °C)ΔT Solve for ΔT: ΔT 14640 J/(300 g)(2.44 J/g ·Ã‚ °C)ΔT 20  °CΔT Tfinal - TinitialTfinal Tinital ΔTTfinal 10  °C 20  °CTfinal 30  °C Answer:  The final temperature of the ethanol is 30  °C. Final Temperature After Mixing When you mix together two substances with different initial temperatures, the same principles apply. If the materials dont chemically react, all you need to do to find the final temperature is to assume that both substances will eventually reach the same temperature. Problem Find the final temperature when 10.0 grams of aluminum at 130.0  °C mixes with 200.0 grams of water at 25  °C. Assume no water is lost as water vapor. Solution Again, you use q mcΔT, except you assume qaluminum qwater and solve for T, which is the final temperature. You need to look up the specific heat values (c) for aluminum and water. This solution uses 0.901 for aluminum and 4.18 for water: (10)(130 - T)(0.901) (200.0)(T - 25)(4.18)T 26.12  °C

Market to Your Preferred Readership

Market to Your Preferred Readership What do you lead with when you publish a book and broadcast news about it? What is the first line of your promotional copy? What leads on your website? How do you word your social media? If its 99 cents for a limited time, you are choosing to market first to those who gravitate to cheap prices instead of those who want a great story. If its FREE for a limited time, you are catering to those who often want something for nothing.   You may argue with me, but hey, you decide what you think will grab the most attention of your customer base. If you start with price, then you think they make their choices with price. If you start with a story hook, then you cater to the reader who doesnt let price dicate their reading choices. There are other options: -Begin with setting, like I often do with Edisto Beach, to grab tourists and beach readers. -Begin with the authors name, assuming you have a burgeoning platform of readers awaiting your next story. -Begin with the genre: mystery, romance, sci-fi, young adult, etc. But out of all of those, many authors, especially new ones, begin with the price. You might reconsider that choice.   If you lead with price, you also may turn aside the serious reader . . . that reader willing to pay the bigger price. These days, that price isnt all that much, especially with ebooks. At the risk of stepping on the toes of many of my indie-published readers, you tell the world that income and price is your driving force for writing . . . not a legacy to the world of stories. I came to this conclusion as I was going through so many emails, Facebook posts, and small press advertisements, deleting all the ones that began with FREE or 99 CENTS or REDUCED FOR A LIMITED TIME ONLY. These days we are deluged with DEALS. So many deals, in fact, that the word has the potential to cheapen.   Instead, when I consider a book, I look for recommendations, blurb endorsements, taglines, and a great gotcha hook in my genre. I want to know what others think of the book. With my TBR stack numbering 50 not including whats on my Kindle, and so many stories pushed out daily, I want to read a good one. Price may not grab a large number of people, but great word-of-mouth always will.

How new perspective on leadership relates to the various types Essay

How new perspective on leadership relates to the various types - Essay Example Another concept that Nonaka and Takeuchi discussed in the interview is the concept of â€Å"phronesis† or practical wisdom. Phronesis is â€Å"the habit of making the right decisions and taking the right actions in context, and relentless pursuit of excellence for the common good† (Nonaka & Takeuchi, Wise Leadership, 2011). They went on further to say that phronesis can be cultivated through very close human interactions. This new perspective on leadership is very much related to the previous concepts of leadership. The other articles on leadership in the textbook also supported the idea of Nonaka and Takeuchi about being an ethical leader. The articles on the textbook also emphasized that leaders must have a passion to do right. This too was advocated by Nonaka and Takeuchi when they mentioned the importance of having a moral purpose and doing what is good for society. The six abilities of a wise leader which were enumerated in Nonaka’s and Takeuchi’s art icle are supportive and intertwined with the â€Å"Seven Habits of Ethical Leaders† taken up in the textbook readings. The first ability of a wise leader is that he can judge goodness. Likewise, an ethical leader has a passion to do right and realize the importance of ethics in the decision-making process.

Nursing Advanced Practice Role Paper -. Florida's Certified registered Research

Nursing Advanced Practice Role -. Florida's Certified registered nurse anesthetists - Research Paper Example Currently there are more than 3,400 CRNAs in the state of Florida and they are the only nurses who are credentialed to provide anesthesia services (Florida Coalition of Advanced Practice Nurses, 2008). In most rural hospitals of Florida, the CRNAs are the sole anesthesia providers. Nationally, the CRNAs are known to deliver 30 million anesthetics each year (American Association of Nurse Anesthetists, 2008). Significant Contributions of CRNAs: The CRNAs have made incredible contributions to nursing and nursing practice. The CRNA’s education and practice has evolved in recent years to fill the growing need surgeons had for anesthetists. Unlike the regular registered nurses, CRNAs function with a high degree of autonomy. The CRNAs provide anesthetic services in surgical, diagnostic and therapeutic procedures. As pioneers in the field of anesthesia, the CRNAs are committed to ensure high standards, based on evidence based practices (Northam, 2009). They provide high quality servic es, which are comparable to those provided by their physician counterparts (Florida Coalition of Advanced Practice Nurses, 2008). The CRNAs have made significant contributions in rural healthcare. ... Barriers Confronted: External Barriers: 1. HMOs, Medicaid and many insurance plans do not provide direct payment for the services of ARNPs as they do for their physician counterparts. In fact they do not even contract with the ARNPs directly (Florida Coalition of Advanced Practice Nurses, 2008). 2. ARNPs are denied medical staff privileges in many hospitals and other medical care facilities (Florida Coalition of Advanced Practice Nurses, 2008). 3. When compared to their physician counterparts, ARNPs are subject to strict malpractice insurance requirements (Phillips, 2005). 4. The ARNPs in Florida can prescribe a wide range of medications. However, unlike the ARNPs in other states, the ARNPs in Florida are not permitted to prescribe controlled substances (Phillips, 2005). Internal Barriers: 1. In the state of Florida, CRNAs are required to work under direct supervision of a medical physician, an osteopathic physician or a dentist (Florida Coalition of Advanced Practice Nurses, 2008). They are required to work within the framework of the protocols which identify the medical acts that can be performed and the conditions under which they can be performed. This greatly limits their ability to function independently. 2. APNs generally have inadequate administrative support and are pressed for time as they try to balance clinical and non-clinical activities (Irvine et al, 2000). This is frequently reported as a major barrier to participating in education, research and leadership activities (Sidani et al., 2000). Benefits to nursing and constituents: The increasing demand for APNs has boosted student enrollment into entry-level baccalaureate programs in nursing by 5.7% (AACN, 2011). The scope

Thousand Splendid Suns Summary Essay Example for Free

Thousand Splendid Suns Summary Essay The novel centers around the friendship between Mariam and Laila. It is split into four parts, with a focus on Mariam in the first part, continuing Laila in the second and fourth, and the relationship between the two women in the third part. Mariam lives in a kolba on the outskirts of Herat with her embittered mother. Jalil, her father, is a wealthy man who lives in town with three wives and nine children. Because Mariam is his illegitimate daughter, she cannot live with them, but Jalil visits her every Thursday. On her fifteenth birthday, Mariam wants her father to take her to see Pinocchio at his movie theater. When he does not show up, she hikes into town and goes to his house. He refuses to see her, and she ends up sleeping on the porch. In the morning, Mariam returns home to find that her mother has committed suicide out of fear that her daughter has deserted her. Mariam is then taken to live in her fathers house. Jalil arranges for her to be married to Rasheed, a shoemaker from Kabul who is thirty years her senior. In Kabul, Mariam becomes pregnant seven successive times, but is never able to carry a child to term, and Rasheed gradually becomes more abusive. A girl named Laila and a boy named Tariq, who are close friends and aware of social boundaries, live in the same neighborhood. War comes to Afghanistan, and Kabul is bombarded by rocket attacks. Tariqs family decides to leave the city, and the emotional farewell between Laila and Tariq ends with them making love. Lailas family also decides to leave Kabul, but as they are packing a rocket destroys the house, kills her parents, and severely injures Laila. Laila is taken in by Rasheed and Mariam. After recovering from her injuries, Laila discovers that she is pregnant with Tariqs child. After learning that Tariq is dead, she agrees to marry Rasheed, who is eager to have a young and attractive second wife, and hopes to have a child with her. When Laila gives birth to a daughter, Aziza, Rasheed is displeased and suspicious, and he soon becomes abusive toward Laila. Mariam and Laila eventually become confidantes and best friends. They plan to run away from Rasheed and leave Kabul, but they are caught at the bus station. Rasheed beats them and deprives them of water for several days, almost killing Aziza. A few years later, Laila gives birth to Zalmai, Rasheeds son. The Taliban has risen to power, and there is a drought, and living conditions in Kabul become poor. Rasheeds workshop burns down, and he is forced to take jobs for which he is ill-suited. Rasheed sends Aziza to an orphanage. Then one day, Tariq appears outside the house. He and Laila are reunited, and their passions flare anew. When Rasheed returns home from work, Zalmai tells his father about the visitor. Rasheed starts to savagely beat Laila. He nearly strangles her, but Mariam intervenes and kills Rasheed with a shovel. Afterwards, Mariam confesses to killing Rasheed, in order to draw attention away from Laila and Tariq, and is executed, while Laila and Tariq leave for Pakistan with Aziza and Zalmai. After the fall of the Taliban, Laila and Tariq return to Afghanistan. They stop in the village where Mariam was raised, and discover a package that Mariams father left behind for her: a videotape of Pinocchio, a small pile of money and a letter. Laila reads the letter and discovers that Jalil regretted sending Mariam away. Laila and Tariq return to Kabul and fix up the orphanage, where Laila starts working as a teacher. Laila is pregnant with her third child, and if it is a girl, Laila has already named her.

The Movie, Real Women Have Curves Essay -- Cinema

Being a curvaceous young woman is hard enough. Especially when you’re trying to find love, you’re seeking approval and anticipating a better future for yourself. The film Real Women Have Curves stresses how important higher education is to a Mexican-American teenager and the wrath she endures from her mother because of her weight and aspiration. Mark Twain stated that, â€Å"Keep away from those who try to belittle your ambitions. Small people always do that, but the really great make you believe that you too can become great† (http://thinkexist.com/quotation/keepaway_from_those_who_try_to_belittleyour/215215.html). I believe I can personally relate to Real Women Have Curves, the reason being is because I’m a daughter, I’m overweight, and I’m seeking a post-secondary education. This is a synopsis of Real Women Have Curves; I’ll reveal why the film is so inspiring to me, I’ll give feedback from movie reviews, and I’ll use documents from my course’s textbook, to fully develop my ideas. Real Women Have Curves is a 2002 movie adapted from a 1987 screenplay by George LaVoo and Josefina Lopez. The film was directed by Patricia Cardoso and produced by LaVoo. The film debuted at the Sundance Film Festival, where it won the Audience Award.

Is it true that Adolf Hitler is the son of Rizal Essay

This is absolutely absurd, but since some fairly educated people actually want to believe it, I write this column.The argument is that Rizal had a German connection, he studied in Heildelberg, and being the Pinoy Don Juan he probably sired a son (why not a Daughter?) who later turned out to Adolf Hitler. Hitler was born 1889, and Rizal left Germany in 1887. Unless Hitler was a delayed baby, that is highly improbable. Although there is no resemblance between the two, it is argued that unlike the tall, blond and blue-eyed Germans, Hitler wanted to propagate into the â€Å"master race,’ Hitler himself was small of stature had dark hair and dark eyes. I would counter this argument by explaining that, contrary to popular belief, Hitler was Austrian not a German. But then Rizal visited in Austria in May 1887 and according to Rizal’s traveling companion, Max Viola, he did spend a night with an unknown Austrian woman. Viola remembers that they were billeted in the Hotel Metropole, Vienna and Rizal â€Å"†¦encountered the figure of a temptress in the form of Viennese woman, of the family of the Camelliasor Margarite of extraordinary beauty and irresistible attraction, who seemingly had been expressly invited to offer for a moment the cup of mundane pleasure to the apostle of the Philippine freedom who until the had enjoyed among his intimates the fame worthy of his glorious namesake, St. Joseph. With the exception of this case I knew of no other slip of Rizal during more than six months of our living together.†

Prejudice and Justice System

I believe that prejudice exists in the criminal justice system. Numerous studies have evidence that have shown prejudice on defendants of color. Social scientists conclude that compared to white defendants, minority groups face a greater chance of prison and severe sentences for identical offenses (Killing With Prejudice). Nearly 51 percent of individuals in a study conducted in Philadelphia, believe that police are more likely to use excessive force against black or Hispanic suspects than white suspects.Minorities are more likely to be victims of police brutality. Not only are minorities treated poorly but also numbers of minorities are sent to trail for non-violent crimes because of discrimination (Racial Discrimination). Of the nearly 2. 1 million adult men and women imprisoned in the United States, roughly 70% are persons of color. People of color are imprisoned disproportionately due to racist laws, and are harassed and mistreated by U.S. agencies. Although people of color commi t most crimes at the same rate as Whites, the unequal targeting and treatment of people of color throughout the criminal justice system, from arrest to sentencing, results in the disproportionate imprisonment of people of color (System as Racist). Hispanics and Blacks who have no criminal record are far more likely to be sentenced than White defendants with no criminal record.Hispanics are twice as likely as Whites to face prison time instead of probation, a fine, or time in a county jail (Racial Prejudice). Blacks are more likely to be sentenced to prison for the same crime than Whites. One third of people of color sentenced to prison would have received a shorter sentence if they had been treated in court the same way as White defendants facing similar charges (System as Racist).

History of Portugal - Overview

History of Portugal - Overview Location of Portugal Portugal is located in the far west of Europe, on the Iberian Peninsular. It is bounded by Spain to the north and east, and the Atlantic Ocean to the south and west. Historical Summary of Portugal The country of Portugal emerged in the tenth century during the Christian reconquest of the Iberian Peninsula: first as a region under the control of the Counts of Portugal and then, in the mid-twelfth century, as a kingdom under King Afonso I. The throne then went through a turbulent time, with several rebellions. During the fifteenth and sixteenth centuries overseas exploration and conquest in Africa, South America and India won the nation a rich empire. In 1580 a succession crisis led to a successful invasion by the King of Spain and Spanish rule, beginning an era known to opponents as the Spanish Captivity, but a successful rebellion in 1640 led to independence once more. Portugal fought alongside Britain in the Napoleonic Wars, whose political fallout led to a son of the King of Portugal becoming Emperor of Brazil; a decline in imperial power followed. The nineteenth century saw civil war, before a Republic was declared in 1910. However, in 1926 a military coup led to generals ruling until 1933, when a Professor called Salazar took over, ruling in an authoritarian manner. His retirement through illness was followed a few years later by a further coup, the declaration of the Third Republic and independence for African colonies. Key People from the History of Portugal Afonso HenriqueThe son of the Count of Portugal, Afonso Henrique was the rallying point for Portuguese nobles who feared losing their power to rival Galicians. Afonso won either a battle or a tournament and successfully expelled his mother, who was styled as Queen, and by 1140 was calling himself King of Portugal. He worked to establish his position, and by 1179 had persuaded the Pope to recognise him as king.Dom DinisNicknamed the farmer, Dinis is often the most highly regarded of the Burgundian dynasty, for he began the creation of a formal navy, founded the first university in Lisbon, promoted culture, founded one of the first insurance institutions for merchants and broadened trade. However, tensions grew among his nobles and he lost the Battle of Santarà ©m to his son, who took the crown as King Afonso IV.Antà ³nio SalazarA Professor of Political Economy, Salazar was invited in 1928 by Portugal’s military dictatorship to join the government and resolve a financial crisi s. In 1933 he was promoted to Prime Minister, and he ruled – if not as a dictator (though an argument can be made that he was), then certainly as a repressive, anti-parliamentary authoritarian, until illness forced him to retire in 1974. Rulers of Portugal

Calculate Cross-Price Elasticity of Demand (Calculus)

Calculate Cross-Price Elasticity of Demand (Calculus) Suppose youre given the following question: Demand is Q 3000 - 4P 5ln(P), where P is the price for good Q, and P is the price of the competitors good. What is the cross-price elasticity of demand when our price is $5 and our competitor is charging $10? We saw that we can calculate any elasticity by the formula: Elasticity of Z with respect to Y (dZ / dY)*(Y/Z) In the case of cross-price elasticity of demand, we are interested in the elasticity of quantity demand with respect to the other firms price P. Thus we can use the following equation: Cross-price elasticity of demand (dQ / dP)*(P/Q) In order to use this equation, we must have quantity alone on the left-hand side, and the right-hand side be some function of the other firms price. That is the case in our demand equation of Q 3000 - 4P 5ln(P). Thus we differentiate with respect to P and get: dQ/dP 5/P So we substitute dQ/dP 5/P and Q 3000 - 4P 5ln(P) into our cross-price elasticity of demand equation: Cross-price elasticity of demand (dQ / dP)*(P/Q)Cross-price elasticity of demand (5/P)*(P/(3000 -4P 5ln(P))) Were interested in finding what the cross-price elasticity of demand is at P 5 and P 10, so we substitute these into our cross-price elasticity of demand equation: Cross-price elasticity of demand (5/P)*(P/(3000 -4P 5ln(P)))Cross-price elasticity of demand (5/10)*(5/(3000 - 20 5ln(10)))Cross-price elasticity of demand 0.5 * (5 / 3000 - 20 11.51)Cross-price elasticity of demand: 0.5 * (5 / 2991.51)Cross-price elasticity of demand: 0.5 * 0.00167Cross-price elasticity of demand: 0.5 * 0.000835 Thus our cross-price elasticity of demand is 0.000835. Since it is greater than 0, we say that goods are substitutes.

Book Review Essay Example | Topics and Well Written Essays - 2500 words

Book Review - Essay Example Even with the good press associated with the Marshall Plan, revisionists and diplomatic historians from both the United States and the sixteen involved nations from Western Europe—even more than fifty years after its ratification and implementation—still debate on its origins, motives and effects (Agnew and Entrikin 2004, p. 1). For instance, historical revisionists have found that â€Å"the economic impact of the plan has been significantly downgraded as scholars concluded that the crisis of 1947 in Europe was less grave than American policy-makers had thought† (Hitchcock n.d.). With these considerations in mind, two of the most substantial and celebrated books on rethinking and revisiting the Marshall Plan will be reviewed in this paper in order to shed some light on what the real purposes and effects of the Marshall Plan are in relation to the United States’ supposed gigantic role in the economic recovery of Europe. The book by Michael Hogan and two chapters from Agnew and Entrikin’s volume will be compared against each other through their contributions to the rethinking of the Marshall Plan. While the former is very detailed, the message that Hogan wants to state is somewhat lost within the detailing of the various facets of the creation of the Marshall Plan. On the other hand, Agnew and Entrikin’s chapters are composed of separate papers that present an all-encompassing view of the Marshall Plan and its effects. These separate chapters that can stand on their own present a more comprehensive and understandable argument as to the sig nificance of the Marshall Plan in history. It can be said then that quality and readability of a work does not depend on the length and an extreme attention to detail, but on a concise presentation of facts and figures that would make the reader understand and accept the argument presented as true. Although there are a lot of differences between the two books, one of the main causes
