The aim of this investigation Essay Example for Free

The aim of this investigation Essay I am given an investigation which I have to plan myself; it is about an unknown organic compound that is either an alcohol, aldehyde, ketone, carboxylic acid, ester or phenol. I have to suggest a series of simple chemical tests, which could be done in test tubes, to distinguish the functional group of this organic compound. I am going to be observing any change of colour, formation of precipitate or the evolution of gas when adding certain chemicals to this compound. The aim of this investigation is to find the functional group by carrying out simple chemical tests and, later, identify the organic compound by using the spectra. Chemicals and Apparatus   10   test tubes   measuring cylinder (5 cm3)   pipette Bunsen burner   Splint   Gas syringe   Unknown organic compound   Bradys reagent   Bromine water Sodium metal Tollens reagent   Calcium Carbonate   Limewater Safety Plan Read the method carefully and understand it before attempting on carrying out any experiment. Have some knowledge of the chemicals to be used to minimise hazards in the procedure. Wear gloves, goggles and a lab coat at all times during the experiment to prevent accidents to one and to fellow pupils. Method Test 1. A Set up the apparatus carefully.   Measure 3 cm3 of the unknown compound into a small measuring cylinder.   Pour this into a test tube.   Add 3-6 drops of Bradys reagent (a solution of 2, 4-dinitrophenylhydrazine in dilute acid) to the test tube.   If yellow/ orange crystals start to appear, then the test has shown a positive result and..   The unknown is proved to be either an aldehyde or a ketone. Move on to Test 1. B   If no reaction happened, then the test has shown a negative result. So skip to Test 2. A. Test 1. B. To distinguish the carbonyl compound, measure 3 cm3 of the carbonyl compound in a measuring cylinder.   Pour this into a new test tube   Add 3-6 drops of Tollens reagent (a solution of silver nitrate in aqueous ammonia) to the test tube.   If a silver mirror forms around the inside of the test tube, the compound is proved to be an aldehyde. However if no reaction occurs, it is a ketone. Test 2. A   Measure 3 cm3 of the unknown into a measuring cylinder.   Pour this into new a test tube.   Throw a pinch of Sodium metal to the unknown. If gas is liberated, quickly light a splint and place it over the test tube. If you hear a popping sound, this confirms that the gas is in fact Hydrogen and the unknown compound is either a phenol, alcohol or a carboxylic acid. Move on to Test 2. B.   If no reaction occurs then the unknown is an ester which should also give a sweet smell. Test 2. B Measure 3 cm3 of the unknown into a measuring cylinder.   Pour this into new a test tube.   Add 6-10 drops of Bromine water to the test tube. * If Bromine is decolourised (from orange to clear) and a white precipitate forms then this confirms that the unknown is actually a phenol. If no precipitate forms then the unknown is either an alcohol or a carboxylic acid. So move on to Test 2. C. Test 2. C   Measure 3 cm3 of the unknown into a measuring cylinder. Pour this into new a test tube. Throw a pinch of Calcium Carbonate to the unknown   If a gas is liberated, shut the tube with a cork that has a hole in it and is connected to a tube and a gas syringe.   The gas should collect in the gas syringe. When gas stops evolving, bubble the gas into 5 cm3 of limewater.   If the limewater goes milky in colour, this proves that the gas is Carbon Dioxide and that the unknown is a carboxylic acid. If no reaction occurs, then the unknown is confirmed to be an alcohol. Fair test Doing a fair test is completely essential for achieving accurate and reliable results which would take a large part in the conclusion at the end, and also for avoiding errors and anomalous results. I will make sure that this happens by many ways, by choosing: 1. Relevant and accurate equipment with very small percentage errors. 2. Washing and drying up the equipment thoroughly after each experiment ensuring that they are contamination-free. 3. Taking measurements carefully as specified by the method. 4. keeping a straight line of sight when reading measurements of solution in the measuring cylinder 5. Always read the bottom of the meniscus of any solution when taking measurements. Bibliography For this investigation, I mainly used the yahoo search engine from the internet as my primary source of information e. g. Bradys reagent; with addition to a variety of books, where I looked up various reactions of compounds. The rest of this investigation is done using my knowledge and understanding of this subject.

Hurricane Wilma :: essays research papers

Damage Hurricane Wilma is the most intense hurricane ever recorded in the Atlantic Basin. The atmospheric pressure was 882 millibars on Wednesday, Oct.19 making it a category 5. Wilma was the 21st storm of the 2005 hurricane season. On Tuesday, Oct.18 the hurricane was a Category 1 hurricane. Hurricane Wilma came just a week after Hurricane Stan, affecting some of the same countries. By Friday, Hurricane Wilma had caused at least 11 deaths in Haiti and Jamaica. Mudslides were becoming a real threat, prompting evacuations in Central America, The Caribbean, and as far as the United States. Hurricane Wilma pounded the western tip of Cuba (figure 3), where the government had to evacuate more than 500,000 people, including 7,000 people from the coastal fishing village of La Coloma. At least one hurricane shelter in downtown Cancun had to evacuate. There were about 1,000 people that had to be moved during the night because the ceiling threatened to collapse. Hurricane Wilma then headed up toward the United States, aiming tworad Collier, Florida. It cost more than 6 billion dollars in damages [1 billion dollars was recorded in Collier, Florida] in Southwest Florida, making it the most damaging natural disaster in 45 years in Florida. Recovery The American Red Cross gave 4,500 hygiene kits to the Mexican Red Cross, and 2,000 hygiene kits to the Bahamas Red Cross Society. These kits include toothpaste, toothbrushes, soap, shampoo and other items. The kits are being sent from relief supplies that were already in Panama. Three months after Hurricane Wilma made landfall, over 300 million dollars had been approved for Florida residents who suffered damages from the disaster.

Research Proposal Sample on Vodafone Uk Customer Satisfaction

In the business industry, it is important to gather customer to make the product and services sold. Therefore, keeping a customer is difficult in the business when it is in the starting stage. A business will find it harder to find prospective and loyal customer when operating abroad. And because of the economic problem that many countries are facing now, another challenge was revived; how to keep the customer? The Customer Satisfaction The customer satisfaction is a business term that measures how products and services supplied by a company meet or surpass customer expectation. It is seen as a key performance indicator within business. In a competitive marketplace where businesses compete for customers, customer satisfaction is seen as a key differentiator and increasingly has become a key element of business strategy1. Every business’s mission is making the customers as their first priority. In accordance to this, the business must fill or serve the satisfaction of their customers according to what preferences that the market is demanding for. For an instance, if the business is in the food industry and the customers’ wants different variations of soup then, the management must look forward to create sumptuous dishes. Some business use different approach in leading their customers in the satisfactory stage like making special for their valued customer or raffle promo or making a sale for some products, anything that will catch the customers’ attention and at the end bringing the profit and customers’ trusts. The business literally promotes their product with the use of their customer because if one customer felt great to their product or enjoyed the service, he/she will make it on the broadcast among with their friends. The value of customers in the business is very high thus; the business needs to find impressions to keep them coming back to their establishment. In the case of finding such market in the other country, is like finding a needle in a vast gassy meadow. It is hard when the business is new to the eye of the customers. It is hard when the business is not prepared in approaching the customers well. It is hard when the business has many competitors in the area. The need for adjustment is highly acceptable. And because of these issues that surround the business industry, the proper guidance is highly appreciated. The Vodafone case can be a basis in catching the customer’s interest. The Vodafone Vodafone UK has more than 17 million customers and is part of the world’s largest mobile community. Vodafone’s leadership in mobile voice and data communications has continued, thanks largely to its focus on developing its brand and customer experience2. In this big company, reaching the respect of the customers is not new to them. Most especially, the Vodafone is a technology-based business and the impact of acceptance is expectedly high. But even a good business like Vodafone still needs to assess their customers and answer every question of their customer. They also consider many opinions and suggestion coming from their customers so that, the evidence in the growing customer acceptance make their gross reach the highest every year. However, the challenge is still there in every kind of business. Customer’s Challenge Vodafone is constantly looking for new ways to drive interaction and enhance the service that we offer to our customers, while at the same time making the life of our people simpler and more rewarding. However, Vodafone recognized that it was not differentiating the needs of its in-store customers or allocating store employees according to their areas of expertise. This meant waiting times could be lengthy and the level of service provided varied on the store employee’s area of expertise. So, Vodafone introduced a re-branding program aimed at improving the customer journey in store, as well as differentiating Vodafone from its competitors. Based on the macro planning principles of â€Å"Organize me, Engage me†, the key components of the refit included greater automation in-store, the option for self-service through kiosks, and footfall counters to track the volume of customers in-store and optimize the customer flow. Benefits to the Customer †¢ Improve the customer experience – customers now have more time to browse the store and choose how to purchase, so everyone benefits from faster and more efficient service, in a more relaxed atmosphere. This has led to a considerable uplift in customer satisfaction. Increase performance – optimized stores outperform other stores. Average contract volumes have increased with average upgrade volumes also increasing. †¢ Minimize business disruption – systems availability is enhanced, with a substantial reduction in support calls and improvement in first time fixes, increasing sales opportunities †¢ Maximize profit margins – self-serv ice significantly reduces the cost of sale especially amongst core pre-pay customers †¢ Enhance productivity – automation of commodity purchases enables faster transaction times and frees up resources to help other customers. The number of customers leaving stores without seeing an advisor is also declining †¢ Reduce support costs – tailoring services and removing duplicate effort and resources has cut costs, while increasing the overall level of support †¢ Optimize resource deployment – increased management information, such as customer numbers, waiting times and sales conversion figures, is helping to track and measure the customer experience in-store and enable staffing roles to be prepared to reflect store and customer requirements. The Business Case for Measuring Impacts The nature of multinational business is complex, shaped by globalization and rapid socio-economic and political change. Sustainability issues are increasingly contributing to this complexity, not least climate change, resource constraints, endemic poverty and ecosystem degradation. Committing to create a more sustainable and inclusive form of globalization and the following are the key objectives3: †¢ Develop a deeper understanding of how global issues such as poverty, the environment, demographic change and globalization affect individual companies and sectors; †¢ Use the understanding of these issues to search for more inclusive business solutions that help to address the issues at both a local and global scale; †¢ Align core business strategies with the solutions identified; †¢ Incorporate long-term measures into the definition of success, targeting profitability that is sustainable and supported by a responsible record in managing social, environmental and employment matters. The Business in Developing Countries Companies recognize the risks and opportunities their operations face in developing countries and the important role they play in influencing change. They rely on transparent legal systems, access to markets and infrastructure services, social stability, healthy and skilled employees and suppliers, as well as consumers willing and able to purchase their products and services. While these conditions are critical for business growth and success, the benefits resulting from the presence of multinational business and the associated in-flows of capital may not reach all sectors of society. The consequence can be a thriving middle and upper class while the low-income segment gets left behind. This can lead to strained relations between business and the communities associated with their activities, increased scrutiny from civil society organizations and greater levels of political pressure from local and national governments, all of which can increase commercial risks for investors3. Conclusion The importance of customer in one business can affect the operation of a multinational company most especially in the developing countries. The success of a multinational company can make an additional growth in their own economy. Getting the heart of the customers are essential to keep the business moving. Although there are many factors that can affect a business that is new in the face of the foreign country, the main strategy that the study can add is to look for a customer that has a same nationality of the business. For example, the American business is new to Japan, therefore, the business should target their very own race first before entering the Japanese culture and became part of their life.References:1.  Ã‚  Ã‚  Ã‚  Ã‚   Gitman, L; & McDaniel, C., (2005).

Does Every Mother Love Her Child - 3307 Words

Does Every Mother Love Her Child? Child Birth can most definitely be a life-altering event that many women will experience at one point or another during their lifetime. The occasion is often described by many as a beautiful, joyful, awe inspiring process. Usually, most women are overjoyed at the news of their pregnancy. They often impatiently await the conclusion of their nine- month gestation in order to meet their new â€Å"bundle of joy† however; the arrival of a baby is not always a happy event for many mothers. Society typically paints a glorious picture of new motherhood where the mother instantly experiences a connecting bond with their child however, realistically, not every mother immediately makes this connection with their baby at†¦show more content†¦Some mothers fall into a period of depression, self-doubt, fear and many other conflicting emotions opposed by what society expects a new mother should feel. These emotions can become severe enough and may impede the new mother’s abili ty to connect with her newborn, care for the baby and/or herself overall creating a psychological, personal and social disturbance to the point where the mother becomes overwhelmed. This alteration to her life would cause an emotional deterioration to the point where she may become capable of harming herself or her baby. This reaction in new mothers is now known as postpartum depression. Upon experiencing this initial disconnect from their child, many mothers feel an intense sense of loneliness, guilt and shame when she fails to embrace the universal ideology that it is the design of nature for her to enthusiastically anticipate motherhood. Now that a lot more information is available about postpartum depression, many avenues are currently being utilized to bring awareness to this growing problem and support is emerging from some unexpected forums to let struggling mothers know that they are not alone. â€Å"This growing attention toward PPD’s potential severity has also resulted in the creation of social policy in Twenty-nine countries. In the United States, The Mom’s Opportunity To Access Help, Education, Research, and Support for Postpartum Depression (MOTHERS) and the Melanie Stokes Acts, legislation
