Easy Method to Prepare a Chemical Solution

Easy Method to Prepare a Chemical Solution Heres a quick overview of how to prepare a solution when the final concentration is expressed as M or molarity. You prepare a solution by dissolving a known mass of solute (often a solid) into a specific amount of a solvent. One of the most common ways to express the concentration of the solution is M or molarity, which is moles of solute per liter of solution. Example of How to Prepare a Solution Prepare 1 liter of 1.00 M NaCl solution. First, calculate the molar mass of NaCl which is the mass of a mole of Na plus the mass of a mole of Cl or 22.99 35.45 58.44 g/mol Weigh out 58.44 g NaCl.Place the NaCl in a 1-liter volumetric flask.Add a small volume of distilled, deionized water to dissolve the salt.Fill the flask to the 1 L line. If a different molarity is required, then multiply that number times the molar mass of NaCl. For example, if you wanted a 0.5 M solution, you would use 0.5 x 58.44 g/mol of NaCl in 1 L of solution or 29.22 g of NaCl. Important Points to Remember Molarity is expressed in terms of liter of solution, not liters of solvent. To prepare a solution, the flask is filled to the mark. In other words, it is incorrect to a 1 liter of water to a mass of sample to prepare a molar solution.Sometimes its necessary to adjust the pH of a solution. To do this, add enough water to dissolve the solute. Then add an acid or base solution dropwise (usually a hydrochloric acid or HCl solution for acid or sodium hydroxide or NaOH solution for a base) to reach the desired pH. Then add more water to reach the mark on the glassware. Adding more water wont change the pH value.

Examples of Diacritical Marks

Examples of Diacritical Marks In phonetics, a diacritical mark is a  glyph- or symbol- added to a letter that alters its sense, function, or pronunciation. It is also known as a diacritic or an accent mark. A  diacritical mark is a point, sign, or squiggle added or attached to a letter or character to indicate appropriate stress, special pronunciation, or unusual sounds not common in the Roman alphabet, according to  L. Kip  Wheeler, a professor at Carson-Newman University in Tennessee. Purpose While diacritical marks are more common in foreign languages, you do encounter them quite often in English. For example, diacritics are often used with  certain French loanwords,  words  that are imported into one  language  from another language. Cafà © and clichà ©Ã‚  are loanwords  from French that contain a diacritical mark called an acute accent, which helps indicate how the  final  e  is pronounced. Diacritical marks are used in dozens of other foreign languages, including  Afrikaans, Arabic, Hebrew,  Filipino, Finnish, Greek, Galician, Irish, Italian, Spanish, and Welsh. These marks can change not only the pronunciation but also the meaning of a word. One example in English is rà ©sumà © or resumà © versus resume. The first two terms are nouns that mean  curriculum vitae, while the second is a verb meaning to return to or begin again.   Diacritical Marks in English There are literally dozens of diacritical marks, but it is helpful to learn the basic diacritics in English, as well as their functions. Some of the marks and explanations are adapted from a  list of diacritical marks  created by Professor Wheeler. Diacritical Mark Purpose Examples Acute accent Used with certain French loanwords cafà ©, clichà © Apostrophe * Indicates possession or the omission of a letter children's, don't Cedilla Attached to the bottom of the letter c in French loanwords, indicating a soft c faà §ade Circumflex accent Indicates reduced primary stress à ©levtor à ´pertor Diaeresis or Umlaut Used with certain names and words as a guide to pronunciation Chloà «, Brontà «, coà ¶perate, naà ¯ve Grave accent Occasionally used in poetry to indicate that a normally silent vowel should be pronounced learnà ¨d Macron or Stress Mark A dictionary notation to signify "long" vowel sounds pÄ dÄ  for payday Tilde In Spanish loan words, the tilde indicates a /y/ sound added to a consonant. caà ±on or pià ±a colada Tilde In Portuguese loanwords, the tilde indicates nasalized vowels. So Paulo *Because marks of punctuation arent added to letters, theyre generally not regarded as diacritics. However, an exception is sometimes made for apostrophes. Examples of Diacritics Diacritical marks are plentiful in English-language articles and books. Writers and  lexicographers  have used the marks to great advantage over the years as these examples show: Acute accent:  Feluda handed over the blue  attachà © case  before he sat down.- Satyajit Ray, The Complete Adventures of Feluda Apostrophe: Lets go down to my house and have some more fun,  Nancy said. Mother wont let us, I said. Its too late now. Dont bother her, Nancy said.- William Faulkner, That Evening Sun Go Down. The American Mercury, 1931 Diaeresis  or Umlaut:  Five young activists were voted into office, bringing political validation to a youth-driven movement dismissed by establishment elders as naà ¯ve, unschooled, and untenable.- Youthquake. Time,   Oct. 6, 2016 Grave accent:  Margret stood in her chamber;Shed sewn a silken seam.She lookà ¨d east an she lookà ¨d west,An  she saw those woods grow green.Tam Lin, The Traditional Tunes of the Child Ballads Macron: neighbornoun  Ã‚  neigh ·bor   \ˈnÄ -bÉ™r\- Merriam-Websters Collegiate Dictionary, 11th ed., 2009 Diacritics in Foreign Languages As noted, there are literally dozens of diacritical marks in foreign languages. Wheeler gives these examples: Swedish and Norse words may also use the circle marking above certain vowels (à ¥), and Czechoslovakian words may use the hacek  (ˆ), a wedge-shaped symbol to indicate a ch sound as in English chill. But unless you learn- or at least develop a proficiency- in those languages, you wont know how to read the words and letters altered by diacritical marks. You should, however, learn where these marks have become common in English- and where they have been dropped, notes  Shelley Townsend-Hudson in The Christian Writers Manual of Style. It can be tricky to know when to retain the diacritical marks, she says: The language is in flux. It is becoming more common, for example, to see the acute accent and diacritics being dropped from the words  clichà ©, cafà ©, and  naà ¯ve- thus,  cliche, cafe, and  naive. But dropping diacritical marks can change the meaning of a word. Townsend-Hudson argues that in many cases you should retain these crucial marks, particularly various accents, to ensure you are referring to the correct word, such as  pà ¢tà ©Ã‚  instead of  pate: The first use means  a spread of finely chopped or pureed seasoned meat, while the second refers the crown of the head- certainly a great difference in meaning. Diacritical marks are also important when you are referring to foreign place names, such as  So Paulo, Gà ¶ttingen, and  Cà ³rdoba  and personal names such as  Salvador Dalà ­, Molià ¨re, and  Karel ÄÅ'apek, she notes. Understanding diacritical marks is the key, then, to correctly identifying and even using many of the foreign words that have migrated into the English language.

ENGINEERING PRODUCTS LTD (CASE STUDY) Essay Example | Topics and Well Written Essays - 1500 words

ENGINEERING PRODUCTS LTD (CASE STUDY) - Essay Example uman Resources (HR) department acquires an importance in the success or failure of the company’s international operations (Quintanilla and Ferner, 2003). The HR department adopts numerous ways in which they could attempt homogenization of the various practices that are being adopted in the Headquarter of the company so that the uniformity in the products with respect to the quality can be achieved, as it is the order of the day that the customers insist on the consistency in the product design and quality. Such consistency can be achieved only by integrating the practices throughout the organization. While the HR Management takes the efforts for integration, they are usually confronted with various issues of power and control which are outlined in this paper while analyzing the case of Engineering Products Limited. The paper also discusses the implications on the managers and non-managers of the organization as a result of such integration efforts. Engineering Products Limited with more than 33,000 workers undertook a restructuring and expansion plan out of which the company expanded globally with more than half of the employees work in their overseas locations. Having three distinct business areas in automotive components, defence and industrial services, the company’s automotive components division being the largest have its employees scattered in the European countries Germany, France and Spain. A smaller percentage of them are placed in UK as well as North America. With the major customers of the company insisting on the same specification of the components produced in all the company’s location, the HR Department of the company is in an attempt to transfer the ‘best practices’ of the company to all its locations. For that purpose they adopt the following methods: One of the key areas of attention of the Management at the Head Quarter of the company is to adopt various management structures that can possibly help the exchange of information among

Knowledge Management (Assignement Question Details as Depicted Below) Assignment

Knowledge Management (Assignement Question Details as Depicted Below) - Assignment Example Now the question arises as to what exactly is knowledge and how is it different from information (Han 2001). Information is data organized in a proper form and in a way so that interpretation and analysis of the material is easy. Whereas when information is acquired by an individual it becomes knowledge. Knowledge is formally defined as acquaintance to information present. The main aim of knowledge management is to make knowledge available in a way to all those concerned in a way that it can be utilize in the best possible way so as to benefit the organization as a whole. This includes both social and technological effort. This subject has gained a lot importance in the corporate environment in the recent years because of several benefits it offers. For instance it reduces the chances of repetitive and redundant work. Everyone in the organization will know what information is already present and they will not waste time and resources on acquiring the same data and they will move ahead from that point, extending the thread from there (Steyn 2003). Apart from this in today’s world where the external environment is so volatile and fast changing that internal stakeholders especially decision makers have to work really fast to catch up with the fast changing trend and stay competitive. In circumstances like these information becomes a vital resource . Those who know are the ones who will survive. Apart from this another advantage that knowledge management offers is the reduction in time required to train new employees or to bring about a change in the organization (Foote 2001). Another aspect of today’s corporate world is that organizations have to stay flexible and to adapt to changes of the market. For this purpose change management has become a famous topic now a day’s for research and development and adequate knowledge management improves this process. The main argument that will be presented by this paper is

Love Story in Terry Kay’s To Dance With the White Dog and in the Movie O :: Comparison Compare Contrast Essays

Love Story in Terry Kay’s To Dance With the White Dog and in the Movie O In the movie â€Å"O†, Desi and Odin, the main characters, share an unstable relationship due to their juvenile romance. The young couple struggle to support and trust one another throughout the movie. They must also deal with the lies and betrayal of their close friend Hugo. Their budding romance can be compared in many ways to the fruitful relationship of Sam and Cora Peek, in Terry Kay’s novel, To Dance With The White Dog. Sam and Cora Peek’s relationship is one that withstands the trial of time. Although both relationships began in the same manner, there are vital differences between the two that drastically separate them from one another. There are many obstacles in the movie â€Å"O† that cause the ultimate failure of Desi and Odin. The young couple has trouble trusting one another because they are inexperienced and just beginning their relationship. There is little stability in Desi and Odin’s relationship partially due to the secretive way in which the couple must see one another. The lies of a close friend quickly make Odin doubt the loyalty of Desi and thus begin to tear apart the young lovers. Throughout the movie doubts and fears are instilled in Odin by his close friend, Hugo. It is these lies that quickly escalate into Odin’s belief of Desi’s betrayal. Ultimately Odin loves Desi so much he can not bear the thought of her with another man, nor can he bear the thought of a life without her. Odin’s irrational thoughts and impulsive nature destroy the love that Desi once harbored for Odin. The love of Odin and Desi is bittersweet in the end. Both of the young lovers die prematurely at the hands of Odin. The love of Odin and Desi is snuffed out due to their inexperienced youth, the pressures of society, and of their peer’s lies. The pressure of Desi’s father and his strong dislike of Odin also helps create doubt in Odin’s mind about Desi. The racial issues play a small role in Odin’s beliefs of Desi. Hugo points out to him that Desi is a white girl and white girls are sly. In To Dance With The White Dog, Sam and Cora Peek share a life long commitment.

Customer Needs and Preferences Essay

DEMONSTRATE THE ABILITY TO PROVIDE INSPIRATIONAL, AUTHENTIC AND PERSONALIZED CUSTOMER SERVICE / IDENTIFYING CUSTOMERS’ NEEDS: Every customer has different needs and wants when they step into the store. As every customer has different preferences, it is essential to personalize the experiences for different customers. To find out what the customers are looking for, we need to ask TED questions. Through the answers the customers give, we will have better insights and understanding about what they are looking for. PROVIDING INFORMATION ON PRODUCTS / EDUCATING CUSTOMERS: Fragrances: As important as sales is, educating the customers is equally crucial. What makes Jo Malone’s colognes so unique is that it is light so it can be layered. They are good on its own but when layered, you will get truly individual effects. Therefore, customers can come up with their own bespoke scents. Candles and diffusers: For every customer that buys the candles and diffusers, our job is to teach them how to use the products. For candles, the customers can only burn for up to four hours and then extinguish it and after burning, the wick of the candle must be trimmed to prevent the candle from tunneling. ASSIST IN DAILY RETAIL OPERATION: Co-ordinate and check merchandise on display: Except for the testers, the products on display are not displayed pieces but actual selling stocks. In Jo Malone London ION Orchard, it often gets busy and customers are always rushing in this fast-paced city so we often do not take the stocks from the cabinets and just sell the products on display instead. During our free time, we will replenish the merchandise on display. By doing so, it would also minimize external theft as we would be able to immediately realize that the product is missing and then report to our superiors and request for them to check the surveillance cameras. By coordinating and checking the merchandise on display, we will also have better insights on approximately how much of each product needs to be reordered. Handle exchanges of merchandise: A lot of the customers that comes to Jo Malone London are customers that are looking for gifts for their family, friends or loved ones. They often do not know what to buy and often purchase the options between our recommendations. To successfully close these deals and not let our potential customers slip out of our hands, we would persuade them to buy by letting them know that we will issue them a sales memo so that the receiver may bring the unused products to exchange for something they like should they not like the gift. DISPLAY PROFESSIONAL IMAGE AND ETIQUETTE: In Jo Malone London, we are required to wear our uniforms, wear formal footwear and put on our aprons and name tags once we are on the sales floor. Grooming is of great importance as it will not only portray our professionalism, our customers will also place their trust in our recommendations when they see how well-dressed we are. What we say to them will seem more professional and convincible to them too. Other than attire-wise, makeup is also required as it would add colors to our face making us look more refreshed and it will also positively affect the perception people has on us. PERFORM DAILY HOUSEKEEPING: As our store is an open layout store with no automatic doors that opens and closes when a customer walks in and out, there is a lot of dust in the store. What adds to the this-this issue is that we have many spotlights in the store which makes the dust a lot more visible. Therefore, it is essential that we wipe the shelves and the tables every morning. On Sunday mornings, we would wipe all products, shelves, and tables. I do not wipe the shelves and tables, it would make our store look dusty, deserted and unsanitary. 2.2 GOOD OR BAD MOMENTS EXPERIENCED GOOD: Seeing the reactions of my customers when I tell them that I am merely an intern. After a few days of the internship, I feel more confident with the amount of knowledge I have which really played a huge part in my ability to persuade customers to purchase. BAD: During our orientation, we were thought to ask TED questions. And then further suggest scents or products to customers based on our insights. But there often are customers that ask what the best sellers are when they step foot in. What makes this situation tricky is the customers because what may be the bestseller may not be what they like. â€Å"May I know what kind of scents you like, miss? Because what may be the bestseller may not be what you would like† would earn me some glares and angry customers that would stomp off. I often encounter such customers and as much as I want to stay unaffected, I really am.
