Molarity of Ions Example Problem

This example problem demonstrates how to calculate the molarity of ions in an aqueous solution. Molarity is a concentration in terms of moles per liter of solution. Because an ionic compound dissociates into its components cations and anions in solution, the key to the problem is identifying how many moles of ions are produced during dissolution. Molar Concentration of Ions Problem A solution is prepared by dissolving 9.82 grams of copper chloride (CuCl2) in enough water to make 600 milliliters of solution. What is the molarity of the Cl  ions in the solution? Solution To find the molarity of the ions, first determine the molarity of the solute and the ion-to-solute ratio. Step 1: Find the molarity of the solute. From the periodic table: Atomic mass of Cu 63.55Atomic mass of Cl 35.45Atomic mass of CuCl2 1(63.55) 2(35.45)Atomic mass of CuCl2 63.55 70.9 Atomic mass of CuCl2 134.45 g/mol Number of moles of CuCl2 9.82 g x 1 mol/134.45 gNumber of moles of CuCl2 0.07 molMsolute Number of moles of CuCl2/VolumeMsolute 0.07 mol/(600 mL x 1 L/1000 mL)Msolute 0.07 mol/0.600 LMsolute 0.12 mol/L Step 2:  Find the ion-to-solute ratio. CuCl2 dissociates by the reaction CuCl2 → Cu2 2Cl- Ion/solute Number of moles of Cl-/number of moles of CuCl2Ion/solute 2 moles of Cl-/1 mole CuCl2 Step 3:  Find the  ion molarity. M of Cl- M of CuCl2 x ion/soluteM of Cl- 0.12 moles CuCl2/L x 2 moles of Cl-/1 mole CuCl2M of Cl- 0.24 moles of Cl-/LM of Cl- 0.24 M Answer The molarity of the Cl  ions in the solution is 0.24 M. A Note About Solubility While this calculation is straightforward when an ionic compound completely dissolves in solution, its a bit trickier when a substance is only partially soluble. You set up the problem the same way but then multiply the answer by the fraction that dissolves.

Ethical Dilemmas Modernization And Its Impact On Society

III. Ethical Dilemmas: Modernization A. Cultural Diminishment Modernization is the unprecedented and rapid change that impacts each culture and is technology driven, as described within the MindEdge resource (2.14). Throughout history we have seen many examples of how modernization has had implicit negative affect on almost every culture. For instance, the profound affects that modernization has had in diminishing indigenous cultures in the Americas, or how modern technologies have eroded the cultural values of specific African cultures. One great example is the fact that modernization completely diminished the culture of indigenous peoples in the Americas. Their beliefs, values, and traditions were based in nature; being one with nature, and nature being one with them. However, the introduction of new technologies was incompatible with their values, and were lost through this adaptation. The same is true of certain African and Japanese cultures. In Japanese culture ethical dilemmas were created out of fear. From the ea rly modern times until the end of World War II certain traditions were still valued in Japan, but Japanese leaders realized that in order to protect Japan from Western colonization, they had to hurriedly rush their modernization. They were successful, and much like the United States their ancient cultures have been reduced to a mere â€Å"souvenir† of times gone by. All of these examples are, at least to me, ethical dilemmas because in order to make room forShow MoreRelatedEthical Issues Of Education Organizational Structure Essay2354 Words   |  10 Pages Ethical issues in Education Organizational Structure Ethics are a set of principles that people use to decide what is right and wrong.

Critical Thinking and Language Essay Example For Students

Critical Thinking and Language Essay Critical Thinking and Language Essay Essay During our 20-year marriage, my wife and I have been fortunate enough to vacation three times in Hawaii. The island of Maui is our favorite. The island of Maui holds a special place in my heart, because of the one-on-one time I was able to spend with my wife. We enjoy the breathtaking scenery and the tranquil sunsets. The highlight of our trips has been the helicopter rides. The helicopter is the only way to see some of the islands awesome waterfalls and other secluded places. The ride can be a little hair raising when it is windy. One of Mauis most visible attractions is Haleakala, the largest dormant volcano in the world. The word Haleakala in the Hawaiian language means the House of the Sun. The top of Haleakala is one of the most outstanding places to watch a sunrise I have ever experienced. Just remember your jackets; it can be a little nippy at 9,000 feet elevation before sunrise. Visitors can ride a bike down to the base of the volcano, if they are just a little off their rocker. These are just a few reasons why Maui is my favorite vacation spot in the world. Using metaphors in the paragraphs above, I was able to describe my experiences with more flair. The images painted in your mind would be different if the metaphors were not used. If language is the mode in which our mind understands the world, and if metaphors are at the heart of language, then metaphors are at the heart of our understanding of the world (Kirby ; Goodpaster, 1999, p. 109). Now let us examine some of the questions about language and thinking critically. What role does language and language diversity play in the critical thinking process? Language helps us make sense of our thoughts. Language is the software that allows our brain to think the way it does; without language the cerebral cortex lies largely unused (Kirby ; Goodpaster, 1999, p. 77). Language must be thought of when trying to communicate. Does the person you are communicating with have the knowledge or have they been exposed to the language so they can understand what you are trying to say? With the many languages in the world, you must be aware that some words do not translate to other languages. When this happens, one must think critically on what other words can be used or other ways to communicate. Using pictures or gestures can help with communicating ideas. How does language empower or limit the expression of our thoughts? At times, everyone becomes speechless. Our thoughts are scrambled and we are unable to express ourselves. At other times, language empowers us to communicate our thoughts and ideas in a way to persuade others to action. The more language we learn about and are exposed to the more we can use it to our advantage. Using our knowledge of language to express ourself more clearly to get a point across. What is the role of critical thinking in persuasion? When persuading someone you must first think of a way to understand how the other person is thinking. Try to see the problem from their point of view. Once you understand their position, then think of a reason for that person to benefit from your position. Make a list of these items so when presenting your position you can refer to the list. Take time to assure that you have thought of all angles that the other person may be viewing about the topic. Present your position on the topic when you have enough time to explain how it will benefit them. Use active listening techniques by rephrasing their response and using eye contact. When attempting to persuade someone be sure to point out all the positive reasons to your point of view and avoid the negatives position. This paper gives examples of metaphor uses and how they expand our understanding of language. My favorite vacation spot was used as an example for this exercise. The paper answers several questions on the role language plays in critical thinking. .u5cd4ff8e3cdc620bb210f1cd75276535 , .u5cd4ff8e3cdc620bb210f1cd75276535 .postImageUrl , .u5cd4ff8e3cdc620bb210f1cd75276535 .centered-text-area { min-height: 80px; position: relative; } .u5cd4ff8e3cdc620bb210f1cd75276535 , .u5cd4ff8e3cdc620bb210f1cd75276535:hover , .u5cd4ff8e3cdc620bb210f1cd75276535:visited , .u5cd4ff8e3cdc620bb210f1cd75276535:active { border:0!important; } .u5cd4ff8e3cdc620bb210f1cd75276535 .clearfix:after { content: ""; display: table; clear: both; } .u5cd4ff8e3cdc620bb210f1cd75276535 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u5cd4ff8e3cdc620bb210f1cd75276535:active , .u5cd4ff8e3cdc620bb210f1cd75276535:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u5cd4ff8e3cdc620bb210f1cd75276535 .centered-text-area { width: 100%; position: relative ; } .u5cd4ff8e3cdc620bb210f1cd75276535 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u5cd4ff8e3cdc620bb210f1cd75276535 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u5cd4ff8e3cdc620bb210f1cd75276535 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u5cd4ff8e3cdc620bb210f1cd75276535:hover .ctaButton { background-color: #34495E!important; } .u5cd4ff8e3cdc620bb210f1cd75276535 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u5cd4ff8e3cdc620bb210f1cd75276535 .u5cd4ff8e3cdc620bb210f1cd75276535-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u5cd4ff8e3cdc620bb210f1cd75276535:after { content: ""; display: block; clear: both; } READ: Who Is Responsible For The Death Of Romeo And Juliet Essay Language helps us all communicate and our ability to think critically .

Death Of A Salesman Charatcer Dvelpomnet Essay Essays -

Death Of A Salesman Charatcer Dvelpomnet Essay A persons attitude is mostly what everyone around him or her will view them as. From this they can tell many things. Whether it is if the person is funny or down to earth or even irresponsible. Many times people change personalities often and they would be classified as being a dynamic type of person. A person who is doesnt change is classified as being a static character. Willy, from Death of a Salesman written by Arthur Miller, is a static character for his inability to grasp reality, his poor parenting and his constant lying to his wife. Foremost, Willy has a problem with his inability to grasp reality. As he grows older his mind is starting to slip. For example, when he talks to the woman and his brother Ben. Throughout the story, Willy dreams of talking to the woman, because the woman is a person that he was dating in when he went to Boston. He was cheating behind his wifes back. Willy basically uses her as a scapegoat when hes hallucinating about her. He blames all of his problems on the woman. For instance Willy says, Cause you do Theres so much I want to make for. (38) This is the evidence right here. Also he dreams about his brother Ben. Willy wishes could be more like his brother who has just passed away a couple of months previously to the story. He also wishes he didnt have to work and could be rich like Ben. He respects Ben for not really working and making a lot of money. Another example of Willys hallucinations are when he says, How are you all? (45) This occurs when Willy is talking with Charley and he starts thinking about Ben. Willys inability to grasp reality never changed throughout the story. Willy also has very poor parenting skills. He has two children Biff and Happy. Willy excuses Biff for a lot of events when he was younger. If Biff stole something, Willy just brushes it off and says that is was no big deal. He didnt even care when Biff failed math and did not graduate from high school. He measured success in how many people you knew not what your grades are. In one breath Willy would say that Biff is lazy and then in the next say hes not. A perfect example of this is when Willy says, Biff is a lazy bum! (16). It is actually chilling at times what he says. To Willy, Happy was not a success and he always thought that Biff was superior to Happy. Even though Happy has a good job and gets all of the women, Willy still doesnt care for Happy. Happy is a womanizer and he gets this from his father. Happy uses women just as his father does to the woman. On page 31 Willy says, You and Hap and I This summer, Heh? (31) This is perhaps the one time Willy is going to make peace wi th Happy and Biff. It is scary that there are fathers just like Willy out there throughout the world. Lastly, Willy has a very bad problem of lying to his wife. Most of the time it is about money and how much he makes. He tells her that he makes all this money but in actuality its nothing. Not even enough to pay the bills. Willy says, Well I- I did whole trip. (35) Linda however, still makes excuses for him and smoothes things over, just as Willy does for Biff. Willy also never tells Linda about the woman in Boston. To him its not important and thinks that if things stay the same everything will be okay. He also lies about Biff to her. She doesnt even know the truth about her own son. Also, he contradicts what he says to her. Linda says, And Willy take lunch. (18) These are prime examples of whats wrong with the family. In conclusion, Willy is a static character. He remains the same throughout the whole play. Which once again means that he is a static character, which means that his attitude doesnt change throughout the course of the story.

One of the most important things in out lives is the ability to make decisions. They can range from small, insignificant choices like what to have for lunch or can be career decisions that could change the course of your life. But one thing is for certain. Many people take the liberty of making decisions for granted. In countries like Australia we have almost full decision making ability. Whereas in countries that are experiencing political or economic turmoil many people cannot make decisions because they are not allowed. So from this we can say that decision making is one of Gods most valuble gifts to us. But decision making is not always a blessing. Some decisions may affect us emotionally.

Case study - Essay Example Studies have revealed that organizations encountering environmental crisis generally endeavour to recuperate their legitimacy by amplifying their environmental disclosures inside their annual reports. An investigation of the corporate disclosures subsequent to a major environmental crisis is likely to provide additional understanding regarding the strategies and accounting theories implemented by such companies. This paper illustrates the legitimacy theory related to corporate disclosure and assesses the practices and activities adopted by BP following its ‘Gulf oil spill crisis’. The legitimacy theory illustrates the rationale behind the revelation of environmental information by corporate organizations. Legitimacy theory states that corporate firms must think about the rights of the society on the whole, and not merely focus on that of their investors. If the firms do not seem to function within the limits of the conduct considered suitable by the society, then the society will take actions to hamper the firm’s right to carry on its business operations. When there is a definite and possible inconsistency amid the business as well as the social value systems, it will result in intimidations to organizational legitimacy in context of economic, legal, and other authorizations (Prabhu 1998; Neu et al. 1998). Neu et al. (1998) opined that the legitimacy of a company is built and preserved by means of symbolic action, which act as elements of the company’s public image. This paper would evaluate the disclosure patterns as well as BP’s strategies following the crisis related to the ‘Gulf of Mexico oil spill’. In April, 2010, a fire explosion took place in the ‘Deepwater Horizon oil rig’, ultimately sinking the vessel and spilling 4.9 million barrels of oil into the Gulf of Mexico, until the well was lastingly plugged. This incident resulted in the death of 11 people, while gravely injuring 17 persons. The event had serious

Definition of Efficient Market Hypothesis Literature review

Definition of Efficient Market Hypothesis - Literature review Example In the realm of financial markets, the value of information is indispensable. It is through the data that most analysts gain more information regarding the market. Market behavior is generally characterized by the flow of information. Therefore, comprehending the data that comes in and out of the market is vital. Through this information, analysts are able to predict prices and movements in the market. In addition, the data that is observed in the market generate perspectives that allow practitioners to forecast long-term movements in the components of financial markets. Although financial markets are hard to grasp, there are suggestions that such markets function with efficiency. Efficiency, when referred to the market, pertains to the changes in price and exchange between buyers and sellers. Apparently, financial markets are highly valued because investors are more inclined with fast-paced forms of revenue generation. Most important, the efficiency of the market makes decision making less risky and more rewarding. Eugene Fama (1970) was the main innovator of the Efficient Market Hypothesis (EMH). EMH implies that financial markets are efficient such that the price of assets, stocks, and other securities reflect all information available; thus, provide an unbiased view of investors regarding future prospects. One important aspect that EMH asserts is that it is seemingly impossible to outperform the market through the use of information known to the market. The information as defined by EMH refers to the data that are unpredictable in the present and appears sparingly in the future. EMH is considered as a fundamental component of modern financial economics (Feinstein, 2000). A compelling view of EHM was provided by Bodie et al. (1996) describing it as a result of rigorous underpinning and supported extensive empirical work. Bowman and Buchanan (1995) identified EMH as meticulously formulated. It is clear that the process in supportive concepts for a developed and competitive securities market. Several executives, however, pointed out some inconsistencies with EMH. These arguments are indeed supported by studies involving various subjects. The essence of EMH has embedded on the information associated stocks and the prevailing price associated with these securities. Malkiel (1987) stated that the varying point of views being presented by the buyers and sellers represent all the information and from the pool, relevant data are gathered. Indeed, the price of stocks will be affected by unexpected news, which of course is still unknown to the investors. There is a natural relationship between markets that efficiently provide available information to their role in efficient market distribution (Stiglitz, 1981). Further studies, on the other hand, pointed out that markets that provide efficient information are not required to provide productive efficiency in the economy. Such description supports tendencies when the market is incomplete and information that is considered as differentiated is costly but valuable. It is understandable that some data appear to be useless. But investors have been creative in creating a sense in this information.
