Fractional Distillation Gas Chromatography Essay Sample free essay sample

Pre-Lab:1 ) When two substances whose molecules are really similar from a liquid solution. the vapor force per unit area of the mixture related to vapor force per unit area of the pure substance. Besides it could be defined as a two liquid are ideal solution when they don’t react with each other and they make no association. 2 ) Are a mixture of at least two different liquid. and known besides as a mixture of two or more liquid in such off that its constituent can non be change by simple distillment. Objective In this experiment we aim to show that we can divide two volatile compounds from a mixture due to the different chemical belongingss of each compound. We will carry through this by a separation process known as distillment. which relies on each compound holding a distinguishable and separate boiling point. Our pure merchandises will be analyzed with gas chromatography to find the success of the distillment. We will write a custom essay sample on Fractional Distillation Gas Chromatography Essay Sample or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Datas and Consequences The distillment curves for our simple and fractional distillment ( See page 3 ) clearly demonstrate that fractional distillment separates the two compounds more wholly. The boiling point ( bp ) of our unknown compounds was taken from the level parts of the fractional distillment curve. Our unknown mixture contained hexane ( bp 69 ?C ) and methylbenzene ( bp 110. 6 ?C ) . Analysis via gas chromatography allowed us to find the comparative per centum of hexane and methylbenzene at fractions near the beginning and terminal of our distillments. Relative per centums have been recorded in the tabular array below. and our computations are shown on page 5. DecisionThis hebdomad we utilized two methods of distillment ( simple and fractional ) to divide a mixture of two volatile compounds. We found that while the simple distillment separated the bulk of the two compounds near the beginning and the terminal of the distilling procedure. fractional distillment produced much more pure fractions. In simple distillment the column was shorter. leting less room for the two different compounds to to the full divide. While heating the round-bottom flask the hexane molecules gain higher kinetic energy faster than the methylbenzene molecules due to their lower molecular weight and lesser intermolecular forces. The longer fractional distillment column allowed the hexane molecules with higher kinetic energy to divide from the lower-energy methylbenzene molecules. After sing the gas chromatograph informations from the fractional distillment we saw that our unknown compounds had about wholly separated. while the fractions from the simple distillment wer e less pure. Although distillment is a good separation technique it is still necessary to guarantee that proper stairss are taken to cut down the opportunities of mistake. Failure to add a boiling bit to the round-bottom flask could let the mixture to heat unevenly. This could let molecules with a higher boiling point to derive kinetic energy before the molecules with the lower boiling point. which would make impure fractions. Watching the rate of temperature addition is besides of import. Leting the temperature to increase excessively rapidly can do dross for the same ground. We forgot to add the boiling bit to the round-bottom flask in the simple distillment. which could hold contributed to the mixture of methylbenzene and hexane that we saw. We made certain to include the boiling bit in the fractional distillment. nevertheless. and did non detect any jobs. Even though both hexane and methylchloride are volatile. they have different chemical belongingss to let for separation and analysis. Hexane is a hydrocarbon with no dipole minute or dual bonds. This means that it has few intermolecular interactions. and will hold a lower boiling point. It besides has a lower molecular weight than methylbenzene. so it will look foremost on the gas chromatograph. Toluene has a benzine pealing with a methyl group attached. Toluene has greater intermolecular forces than hexane because the benzine pealing withdraws negatrons from the methyl group. This creates a little mutual opposition to the molecule that increases intermolecular forces and increases the boiling point. Since methylbenzene has a greater molecular weight than hexane it will look 2nd on the gas chromatograph. This experiment illustrates how utile the different belongingss of compounds can be while seeking to sublimate mixtures of compounds.

Ethical Dilemmas American Behavioral Scent -Myassignmenthelp.Com

Question: Discuss About The Ethical Dilemmas American Behavioral Scent? Answer: Introduction The topic focuses on the concept of learning organisation considering the case study of the business organisation named Commonwealth Bank in Australia. Various issues and scandals have arisen, which has not only deteriorated the brand name and image, but also has degraded the business performance. To overcome these issues, responding to changes will be essential not only to meet the ethical standards but also for maintaining consistency and enhanced business performance within the organisation (Commbank.com.au 2018). There are barriers that have created issues to manage organizational learning whereas proper recommendations are provided to ensure that the Bank remains ethical and foster growth and learning with time. Analysis of repeated ethical scandals through the lens of organisational learning theories Learning organizations are managed with the consideration of various factors including the obtaining and management of knowledge. The organizational learning theory is related to the ways by which learning is created and managed and how these are related to the business functioning. Learning organisation allows for enhancing the learning capabilities and allow the staffs to improve their strengths, skills and abilities, furthermore resolve the issues that may hinder the growth and development of the business as well as its employees (Tortorella et al. 2015). The historical aspects including the implications of past activities could also deteriorate the rate of growth and hinder the long-term view of learning, thereby might result in creating an unhealthy atmosphere within the workplace (Hanna, Crittenden and Crittenden 2013). One of the major scandals where Commonwealth bank was involved had been the money laundering scandal due to the decrease in shares of the bank. Due to the poor learning abilities, prior assumptions were not made regarding the return on investments. Nearly 8,00,000 shareholders or investors shared huge amounts of losses due to the violation of money laundering laws, according to the Australian police department. Based on the reports presented by the Australian Transaction Reports and Analysis centre, the bank shares have fallen to more than 5 percent, which resulted in 54000 breaches of money laundering and even avoiding the counter terrorism financing laws (Limwichitr, Broady-Preston and Ellis 2015). Based on the organizational learning theories, it was important for the financial institution to predict the outcomes and even make sure that the laws are obeyed. No proper training and learning approaches were provided to the employees, because of which, they failed to understand the mo ney laundering laws properly and this resulted in breaking those laws. A severe financial crime was committed, which not only damaged the reputation of the company but also made many shareholders face huge amounts of losses in business (Gil and Mataveli 2016). Laws were breached regarding the funding for terrorism activities too, which could also be considered as a major scandal faced by Common wealth Bank, Australia. Analysis of existing barriers to the organisational learning at the Commonwealth Bank There are multiple barriers associated with the organizational learning such as lack of proper leadership skills, short-term focus, focus on self-performance rather than the entire teams performance and success, lack of ability to respond to changes managed within the organisation. One of the major barriers to the organizational learning could be the misconduct of the staffs, because of which, many customers were lost and the company failed to comply with the regulatory standards, codes of conduct and laws implemented by the Australian Government (Moss et al. 2016). Many of the staffs were found to violate the laws, rules and regulations regarding the money laundering, which resulted in financial loss and damaged the companys reputation too. This kind of unethical behavior has made many customers terminate their accounts from the bank and the shareholders who invested on the company did not get the return on investments as expected by them. There was lack of control and the customers were provided with inappropriate advices and decisions regarding the investments and bank accounts opening. The customers placed complaints, which were later found as true and immediately the staffs had been terminated (Choi, Kim and Yoo 2016). Another major barrier to organizational learning faced by Commonwealth Bank in Australia was the management of hierarchical structure, which resulted in allowing only the top management to make decisions and policies. Thus, the organizational structure was unyielding and it made the organisation fail to adapt to the dynamic changes within the business environment. The online customers services were not good enough, which created dissatisfaction among the customers (Bartsch, Ebers and Maurer 2013). The participation of the employees was quite low, due to which, only the top-level management made decisions and so Commonwealth Bank of Australia lacked behind the other competitors in business. With the advancement in technology and communication nowadays within the banking industry, Commonwealth Bank has been lacking in consistency to respond to the changes in technology. Customers even provided complaints on the social media platforms, which has damaged the reputation of the company and reduced the sales revenue too (Duffield and Whitty 2015). Recommendations to Commonwealth Bank to become an Ethical Learning Organisation It is recommended to overcome the barriers for planning a proper flow of income and manage proper control for improving the performances of staffs within the organisation. A proper control system should be implemented for allowing the workers of the company to make effective decisions and even provide proper advices to the customers who might be willing to open bank accounts or want to make investments. The performances of the workers would also be measured, which could track the business activities and ensure that the transactions cold be verified. The hierarchical structure was a major barrier to organizational learning, because only the top management was allowed to make decisions. It is recommended to change the organizational structure and ensure that the working procedures are flexible enough to adapt to the changes and maintain a positive workplace and business environment (Paulin and Suneson 2012). Social media involvement is recommended, though regular monitoring will be ess ential for checking any complaints or questions provided by the customers. This would help to understand their need and requirements and provide relevant solutions according to that, furthermore prevent customers from switching accounts with other banks through betterment of financial services delivery (Prinsloo and Slade 2013). This would allow the company to sustain in the competitive business environment. To manage the corporate social responsibilities, teaching the children about the value of money and maintaining diversity at the workplace could be beneficial too (Largent, Miller and Joffe 2013). By enabling ethical training, ethics and integrity should be maintained, furthermore could enhance the skills and knowledge level of the staffs of Commonwealth bank to follow the codes of conduct and maintain steady business functioning as well. A positive work culture is recommended for managing creativity, deliver value and promote innovation for the new products and services. This is crucial for the organisation to enhance its ability to learn and manage production of new financial services for keeping the customers satisfied. It is also recommended for Commonwealth bank to develop a good work culture for creating an open environment where new ideas are promoted and uniqueness is brought to improve the areas of planning, learning and production. This is how the company would become ethical by considering each and every employees opinions and responses and then make a perfect decision and make them feel valued for the organisation as well (Slade and Prinsloo 2013). This would manage the resources properly, provide encouragement to the supervisors and provide enhanced organizational support too. Conclusion The report was prepared to discuss the management of ethical learning considering the business organisation Commonwealth bank in Australia. The financial institution faced major issues related to the money laundering activities and even poor control system management. This created difficulties for the people to deliver the right kinds of services to the customers and the staffs even failed to provide proper advices regarding the financial and banking matters. There were other barriers to organizational learning too such as inappropriate hierarchical organizational structure, where decisions were made by the top management only and failing to cope up with the technological changes. The organizational structure was changed and ethical training was provided to the staffs for making them obtain relevant skills, knowledge and expertise. This could allow them to maintain proper values and ethics and ensure successful business functioning, furthermore stay ahead of the competitors in the co mpetitive business environment.

Text Painting in LHeure Exquise by Reynaldo Hahn Essay Example For Students

Text Painting in LHeure Exquise by Reynaldo Hahn Essay Reynolds Hahn (August 9, 1875 -January 28, 1947) was a Venezuelan, naturalized French, composer, conductor, music critic, diarist, theatre director, and salon singer. Best known as a composer of songs, he wrote in the French classical tradition tot the m ©oldie. The fine craftsmanship, remarkable beauty, and originality of his works, Probably the most beautiful pieces (in my opinion) ever composed by Hahn was Allure issues with is simplicity and perfect illustration of text. The (Preach) text reads: La Lune balance ITT Dana Sees Bois De chase branches art nun voice souse la ram ©e. O been aim ©e. L ©tang reef ©et, profound mirror, la silhouette du sale noir o lee vent pleurae. R ©vans, test lures. Un vast et tender appeasement assemble descended du firmament queue Vaster irises. Chest Rehire issues! Translated: The White moon shines in the woods. From each branch springs a voice beneath the arbor. Oh my beloved, Like a deep mirror the pond reflects the silhouette of the black willow where the Wind weeps. Let us dream! It is the hour A vast and tender calm seems to descend from a sky dad iridescent by the moon. It is the exquisite hour! The accompaniment to the piece is quite lovely and is perfect for the txt of the piece. The speaker in this art song, which is usually sung by high voice although it has been transposed, is speaking of how perfect the setting is for them to be with their lover. While the meter of the music flows along in a docile sense it almost has a tedious sense about it. The detail to which the speaker lends their description gives a little bit of anxiety almost because of how delicate the scene seems to be. Its almost as if the speaker vans to be careful not to break the perfection as if it has the tensile strength Of a cobweb even. We will write a custom essay on Text Painting in LHeure Exquise by Reynaldo Hahn specifically for you for only $16.38 $13.9/page Order now Small breaks in the accompaniment to be left to the soloist give a sense of very careful treading so as not to send anything Off kilter. The vocal line sits in the middle range providing ease and allowing the vocalist to portray simplicity and awe, these two characteristics being carefully energize in the sphere Of anxiousness and carefulness. The vocal line is occasionally taken into the higher part of the range UT is still kept quiet, almost in a kind of accidental excitement that must be quickly drawn back. In the last verse of the piece the text and rhythm are brought to their most excited state where Hahn almost doubles all of the rhythms used in the verse the duple meters where the poet speaks of a a calmness descending on them. This lines subtle tension is brought perfectly relieved by a last line entering the upper loftier part of the voice , yet still quieted, where it the brought almost into a homily like cadence that allows for some free mime to he taken between the collaborative instruments and the voice. I would say that this piece is loved by audiences of all kinds pretty much across the board and the text could almost not be taken in a romantic text although believe most people perceive it this way. It seems to me however to me that it could also be noticed as a lullaby, maybe between a mother and child. Either way the text would still be just as delicate and Hahn would have been just as brilliant in his interpretation.

Basic Geography of Rivers

Basic Geography of Rivers Rivers provide us with food, energy, recreation, transportation routes, and of course water for irrigation and for drinking. But where do they start and where do they end? Basic Geography of Rivers Rivers begin in mountains or hills, where rain water or snowmelt collects and forms tiny streams called gullies. Gullies either grow larger when they collect more water and become streams themselves or meet streams and add to the water already in the stream. When one stream meets another and they merge together, the smaller stream is known as a tributary. The two streams meet at a confluence. It takes many tributary streams to form a river. A river grows larger as it collects water from more tributaries. Streams usually form rivers in the higher elevations of mountains and hills. The areas of depression between hills or mountains are known as valleys. A river in the mountains or hills will usually have a deep and steep V-shaped valley as the fast moving water cuts away at the rock as it flows downhill. The fast moving river picks up pieces of rock and carries them downstream, breaking them into smaller and smaller pieces of sediment. By carving and moving rocks, running water changes the earths surface even more than catastrophic events such as earthquakes or volcanoes. Leaving the high elevations of the mountains and hills and entering the flat plains, the river slows down. Once the river slows down, the pieces of sediment have a chance to fall to the river bottom and be deposited. These rocks and pebbles are worn smooth and get smaller as the water continues flowing. Most of the sediment deposition occurs in the plains. The wide and flat valley of the plains takes thousands of years to create. Here, the river flows slowly, making S-shaped curves which are known as meanders. When the river floods, the river will spread out over many miles on either side of its banks. During floods, the valley is smoothed and tiny pieces of sediment are deposited, sculpting the valley and making it even smoother and more flat. An example of a very flat and smooth river valley is the Mississippi River valley in the United States. Eventually, a river flows into another large body of water, such as an ocean, bay, or lake. The transition between river and ocean, bay or lake is known as a delta. Most rivers have a delta, an area where the river divides into many channels and river water mixes with sea or lake water as the river water reaches the end of its journey. A famous example of a delta is where the Nile River meets the Mediterranean Sea in Egypt, called the Nile Delta. From the mountains to the delta, a river does not just flow - it changes the surface of the earth. It cuts rocks, moves boulders, and deposits sediments, constantly attempting to carve away all of the mountains in its path. The goal of the river is to create a wide, flat valley where it can flow smoothly towards the ocean.

Security Issues Related to the Expansion of the City Airport Research Paper

Security Issues Related to the Expansion of the City Airport - Research Paper Example Security issues related to the expansion of the city airport In post 9/11 world the security and protection are increasingly challenging tasks. Managers and business leaders have an important role, especially the security managers. The city airport is a busy airport operating close to its capacity. The expansion project includes the construction of a new runway and terminal. This is not an unusual situation, many other airports around the world. In this paper is presented the lessons learned with Chicago and Minneapolis airport expansion The implications related to an airport expansion are several. They are related to political issues, construction and environmental and demanding during the operation ( Neufville, 2008). From a Security Manager perspective produce a report about this project. This report will respond to the following questions: What are the full range of risks faced? What should the security strategy be? What additional security products and services might be needed? What special organisational structures might need to be created? What can be learnt from comparable projects that have occurred? What links might be developed with the public policing agencies, media and interest groups? Is there scope for security to be organised and arranged to bring financial benefits to the company? Would you advise the Board to reconsider their decision? In order to improve the efficiency in the process of decision making is important to define and measure all the benefits and risks of the airport expansion. It’s recommended a SWOT analysis. Risks Faced The airport expansion has associated major sources of uncertain and risks. â€Å"In the current climate, long-term forecasts cannot be developed with any degree of confidence. On the contrary, as has been extensively documented, forecasts of airport traffic today are ‘always wrong’.† ( Neufville, 2008). As said the expansion of the airport will the constructed on the adjacent land whic h is currently a small forest. Next to it there is a country park popular with local residents, which includes: children’s play area, lake with ducks/swans etc, football pitches. There is also a housing estate next to the park and forest with over 1500 residents. The proximity with the existing infrastructure implies some risks to the success of the project. The risks and uncertainties over the lifespan of the expansion could be divided into three major groups: - Political issues and Government policy; - Construction and environmental; - Demand during operation. Political issues and Government policy The project of the airport expansion requires government and local authority permits. These processes are intrinsically related to the decision-making process those entities. Therefore the delays in the decision-making process are a risk. When depending on the decision of those authorities the project could be affected by too many advances and drawbacks.  Ã‚  

Smartphones Annotated Bibliography Example | Topics and Well Written Essays - 500 words

Smartphones - Annotated Bibliography Example There are a thousand parts of the smartphones that cause a range of concerns. Such issues range from freezing to the force closing of application and booting attached problems just like computer or tablet problems. The warranty coverages halt after some years and hence the customer remains responsible for the hardware or software replacement. In addition, cost a chief setback to smartphones with respect to owning and operating smartphones (Perlow 34). It is interesting to uncover that one’s monthly cell phone bill for the smartphone is higher as compared to ordinary cellphones. Chief Cellphone carriers like Verizon, AT&T, and T-Mobile and Sprint users pay up to 75 and 120 dollars monthly for Smartphones excluding taxes and fees. The initial costs of acquiring smartphones are also high with a minimum $600. However, it is beneficial to signing on with carriers to due to discounts after signing a contract service. Smartphones provide capabilities such as those of Blackberry, iPhone, Windows Phone and Android that far much compared to basic clamshell and flip-style phones. Smartphones presents users with ability to check for social media sites, email conversation and transaction performance like read books and instant messages. As the smartphones provide capabilities that ordinary cellphones, a sense of convenience crops in those basic cells cannot provide. The GPS application capabilities offer users turn-by-turn directions to anywhere from all location. Bank account balance can be accessed; social networking further helps users keep close ties with relatives, friends and families (Perlow 52). The used smartphones will cost less relative to new ones but still perform the functionality required. They are purchased on auction sites such as eBay as well as when advertised in local newspapers classifieds sections and Craigslist. However, one must assess the smartphone for any past
