Names and Functions of Chemical Elements in Fireworks

Fireworks are a traditional part of many celebrations, including Independence Day. There is a lot of physics and chemistry involved in making fireworks. Their colors come from the different temperatures of hot, glowing metals and from the light emitted by burning chemical compounds. Chemical reactions propel them and burst them into special shapes. Heres an element-by-element look at what is involved in your average firework. Components in Fireworks Aluminum: Aluminum is used to produce silver and white flames and sparks. It is a common component of sparklers. Antimony: Antimony is used to create firework glitter effects. Barium: Barium is used to create green colors in fireworks, and it can also help stabilize other volatile elements. Calcium: Calcium is used to deepen firework colors. Calcium salts produce orange fireworks. Carbon: Carbon is one of the main components of black powder, which is used as a propellant in fireworks. Carbon provides the fuel for a firework. Common forms include carbon black, sugar, or starch. Chlorine: Chlorine is an important component of many oxidizers in fireworks. Several of the metal salts that produce colors contain chlorine. Copper: Copper compounds produce blue colors in fireworks. Iron: Iron is used to produce sparks. The heat of the metal determines the color of the sparks. Lithium: Lithium is a metal that is used to impart a red color to fireworks. Lithium carbonate, in particular, is a common colorant. Magnesium: Magnesium burns a very bright white, so it is used to add white sparks or improve the overall brilliance of a firework. Oxygen: Fireworks include oxidizers, which are substances that produce oxygen in order for burning to occur. The oxidizers are usually nitrates, chlorates, or perchlorates. Sometimes the same substance is used to provide oxygen and color. Phosphorus: Phosphorus burns spontaneously in air and is also responsible for some glow-in-the-dark effects. It may be a component of a fireworks fuel. Potassium: Potassium helps to oxidize firework mixtures. Potassium nitrate, potassium chlorate, and potassium perchlorate are all important oxidizers. Sodium: Sodium imparts a gold or yellow color to fireworks, however, the color may be so bright that it masks less intense colors. Sulfur: Sulfur is a component of black powder. It is found in a fireworks propellant/fuel. Strontium: Strontium salts impart a red color to fireworks. Strontium compounds are also important for stabilizing fireworks mixtures. Titanium: Titanium metal can be burned as powder or flakes to produce silver sparks. Zinc: Zinc is used to create smoke effects for fireworks and other pyrotechnic devices.

Assessment Is The Process Of Gathering Information And...

Assessment is the process of gathering information and evidence to assess a learner. Assessors will work with the learner to identify gaps in learning, knowledge and skills and provide learning objectives with feedback to enhance their knowledge base, skills and progression. Assessment comes in differing forms and can be used either singularly or in conjunction with another to provide this information. Assessments will gather information and a judgment can be formulated in regards a learners competence, knowledge and skills. Some assessments used can be summarised below. †¢ Observation of performance in the work environment. This method is based upon observations being taken in the work place and will be based on fact and specific work based actions, behaviours and tasks. It allows the assessor to assess the learners’ performance and knowledge of their role. It allows for feedback and input from both the assessor and learner, whereby future goals and learning aims can be set. Observations will allow for a judgement on knowledge and competence. †¢ Examining Products of Work This method is a resource used by the learner from their workplace, for example, care plans, reports, risk assessments, policies or procedures that they use or contribute to on a daily basis. It will aid in professional discussions and provide evidence of competence and knowledge. †¢ Discussion with the Learner This method involves a comprehensive discussion between learner and assessor toShow MoreRelatedAssessment Process2463 Words   |  10 PagesQualification outline P. 3 The assessment process P.4 Types of assessment P.5-6 Concepts and principles of assessment P.7-9 Stages of assessment P.10 Understand how to plan assessment P.11-13 Holistic assessment P.14 Risks of assessment P.15-16 Understand how to make assessment decision P.17 Understand different types of assessment methods P. 18-20 The use of technology in assessment process P.21 Responsibilities of the assessorRead MoreEducational Psychology and Assessment1205 Words   |  5 PagesCertificate in Teaching in the Lifelong Learning Sector - (Intensive) |Unit Title |CTLLS UNIT 3 - Principles Practice of Assessment | |Theory Assessment Number | | |Candidate Name |KEN PHILLIPS |Candidate Number | | |Date Issued | Read MoreDescribe What Your Role, Responsibilities and Boundaries Would Be as a Teacher in Terms of the Teaching Training Cycle6111 Words   |  25 Pagesqualifies the learners to assess an NVQ in the job and area of expertise that they are competent in.

Creating market value for consumers Free Essays

The plan is for the creation of an ethnic Arabian/ Middle Eastern restaurant offering entertainment programs in Fairfield County, Connecticut. Arabian Nights is a trendy new ethnic restaurant located in Fairfield, Connecticut. The emphasis of the restaurant is going to be Oriental cuisine, with up-to-date and traditional recipes. We will write a custom essay sample on Creating market value for consumers or any similar topic only for you Order Now Besides, Arabian Nights will offer regular simple dishes for the companions of the consumers who for some reason are not attracted by the rich and spicy Oriental food. The restaurant will also offer evening shows featuring costume displays, fashion shows, dancing, and singing so that customers could taste a flavor of the Orient. In our opinion, the market need for the creation of this product is conditioned by the relative scarcity of ethnic cuisine offerings in the vicinity of Fairfiled, CT. The area also misses rich entertainment possibilities. The interest in ethnic foods surges in the US market as people are increasingly dining out and their tastes shift towards gourmet cuisine. Bakers’ Dozen report on food service trends for 2004 cites the trend for original ethnic foods as one of the most important for the year. The authors of the study believe that the original recipes will increasingly replace â€Å"mall ethnic fare† that is typically â€Å"Americanized version of ethnic food† (Bakers’ Dozen 2004). As one can see from the Megasite Guide to Dining, Fairfield county restaurant owners offer their customers predominantly uniform meal styles, flavored by some intermittent Chinese, Japanese and European ethnic cuisines (Megasite Guide to Dining). In part this is conditioned by the relative lack of ethnic diversity in the area cited by the participants of the high school focus group (Long Range Plan 2001-2006). Arabian Nights will be the first restaurant in the area that will combine eating out with entertainment. The shows will be relatively low-priced as compared to the offerings of the entertainment places like concert halls and theaters ($6-10 per person admission fee on the night of the performance), and will add excitement to the evening out experience. The restaurant will cater both to those who are interested in the Middle Eastern culture and customs and those who have only a fleeting wish to get an exotic meal. The decorations of the interior will feature paintings of the Arabian lifestyle, exquisitely designed modern and ancient maps of the region and a few recipes of the simplest Middle Eastern foods set in trendy frames. In the future, the restaurant will aspire to become the renowned local venue and a community specialty. The focus of the restaurant will be on both food and entertainment. Considering the public’s interest in exotic dishes, Arabian Nights will offer the Oriental food, the area untapped by other fashion restaurants in the vicinity. As today’s public is taking an interest in health diet, the restaurant needs to emphasize the fact that it is using healthy ingredients, and the food is not fattening. The potential customers will include young couples in their 20s and 30s, as well as older public. The potential visitors will be also couples with kids who might take an interest in the show and educational displays in the establishment. The message of the product offerings will be communicated to consumers using various communication channels. The primary vehicle will be advertising including ads in local newspapers, quick commercials on local TV channels, and Internet ads placed on websites on local entertainment and dining opportunities. Besides, the first shows are expected to attract a great deal of publicity that will be supported by the company’s pres releases. The restaurant hoped to achieve publicity also by granting support to the local â€Å"Feed the Hungry† programs. Works Cited Bakers’ Dozen Foodservice Trends: Trends for 2004.

In Encyclopedia Of Psychology And Religion - Myassignmenthelp.Com

Question: Discuss about the InEncyclopaedia Of Psychology And Religion. Answer: One of the most important theoretical aspects in psychology is the concept of reincarnation. The reincarnation is one of the most debated topics in the fields of psychology and philosophy. There are no perfect ways to prove it but there are no ways to disapprove its existence either given the modern technology. There are a number of cases that are thought to be the cases of reincarnation. Reincarnation is held in a high regard among a number of societies and religions (Jones, 2017). The Egyptians to the Hindus there have been a number of references to the concept of reincarnation in the religious text. In the modern scientific world, it exists, but as an anomaly and a hypothesis, not believed, until proven. The hypothesis is majorly dependent on the cases of children having a memory and a detailed knowledge of their past life. Throughout history, there have been a number of cases of people giving vivid details of their past life with intricate detail. There are number of cases in history and mythology portrayed as stories ascertaining the ancient belief in reincarnation. The Hindus take reincarnation and life as a chance to do good deeds and the destiny of their present life depends of the deeds of the past life (Bailey, 2014). Among a number of psychologists, this is seen as a conclusive proof of the existence of a number of lives and they have been passing as phases. There are a number of theories, which have been trying to explain the existence of such memories among children. Still, like every supernatural explanation in the present time the theory remains as a context of debate and a hypothetical entity. The existence of such memories in children is very much an anomaly as they cannot be explained and the justified explanation of such incidents are not available. The different situations are taken int o accounts that have led to the belief in these stories. Firstly, children who have no personal motive behind such actions and often suffer in the process of remembering these memories tell them. Secondly, the intricate details that are often included in the complete stories of these children without any prior knowledge of the person they are talking about is surprising. Thirdly, the vast expanse of the distance that is often there between the children telling the stories and the locations of their previous existence show that they might not have any credible knowledge of the person beforehand, making the stories believable. There have been a number of active psychiatrists studying this phenomenon for a long time and are often shocked by the incidents reported to them. The proof of reincarnation cannot be refuted because there are no scientific explanations of the knowledge that the children possess. There are various theories though put forward by the psychiatrists who refute the presence of any such anomalies in the cycle of human existence (White, 2015). There are various scientific theories too that try to explain the reason behind the children remembering the details of the past life. Few of the theories that deserve mention are the past life regression theory, the genetic memory theory and the theory of linear time. The hypothesis of reincarnation is not dependent on a single case study, there are examples of a number of cases reported throughout the world where the children remember the details of their past life. The people refuting reincarnation and not believing the examples of the children put forward a simple question, why does not everyone remember their past life? One of the major proponents of the reincarnation theory, Dr Brian Weiss explains in his book about a patient who recalled a number of past life incident during a hypnotism session. The doctor wanted to address the issues of a number of phobias she faced and suffered throughout her childhood but was astounded when the root of the phobias led him to a number of past lives during the hypnosis sessions. This concept if any true explains a lot about a number of inexplicable emotions felt by people. A number of emotions like hatred and anger towards someone or something can be alluded to its experience during the past life (Jones, 2017). There is another facet of this theory and any other theory of reincarnation; they all ascertain the existence of soul. There are a number of examples throughout history of people claiming to be reincarnations but a few have stood up to the tests of certainty. Therefore, in this essay, the cases studied by renowned psychiatrist Jim Tucker are portrayed as examples of reincarnation. One of the best examples is the case of James Leininger, a young kid claiming to be a fighter pilot who had been killed in action. Initially, even his family was skeptic about the claims he was making but the amount of knowledge he had about the aircrafts of World War II made his claims irrefutable. Firstly, it is not possible for a kid as young as 4 to know the difference between the bomb in the plane and the drop tank. Secondly he vividly remembered the name of the ship from which he flew, and it was not such a renowned one that the people would remember. Thirdly, and the most important of them all was that he could correct the name of the plane shown in a documentary which only a veteran would remember. Moreover, the nam e he claimed he had in his past life was enrolled as a martyr serving on the aircraft carrier (Tucker, 2016). Though very convincing, this is far from being the only case where a person has claimed to be reincarnated. There is another case of a child named Ryan, who would claim of meeting stars like Rita Hayworth and living in Hollywood. This was a very weird claim and what turned out was even more unbelievable. The claims that the child had made were of being the reincarnation of Marty Martyn who had been a side actor and an agent of a number of stars. The claims could have been questionable and learnt or taught by someone but the details he knew surprised everyone. Ryan claiming to know the number of marriages Marty Martyn had and most important fact that Ryan disclosed was that Marty had two sisters. This claim astonished everyone since Martys own daughters did not know about this (Mills Tucker, 2015). Jim Tucker not only studied these cases but formulated a theory of what might be causing the reincarnations and hoe the children might be having these memories. His theory depends on the fact that consciousness has led to the formation of material world and not the other way round. This shows that the consciousness does not require a brain to exist and it can exist and flow to the consciousness of another person giving them memories of the previous person. Despite the theory looking believable mostly, the counter to this claim of Tucker lies in one of the case studies conducted by him. The case of Kendra Carter is the one which shows a great disparity from this theory shown by Jim Tucker. When asked for the reason for being extremely attached to her swimming teacher, Kendra told that she was her mother who had aborted Kendra in her past life. This was a very weird claim but when it was verified, the swimming teacher indeed had an abortion nine years ago (Drewes, 2005). This is also c onsidered a case of reincarnation but the attachment of the consciousness to the fetus, which was yet to be born to a girl remembering the face of woman born to remains questionable. The consciousness can feel attached to the person who was their parent but a person remembering a face that they had not seen puts the claim in question. There are a number of theories in science, which try to prove these memories. One of the most important theories are relating to time. There are claims that some distortions in time which had led to the formation of such memories among children. The distortion in the time space continuum is said to cause these memories to be formed, but like the reincarnation theory, this too is hypotheses. Despite whatever claims are made by the different psychiatrists supporting reincarnation there is no way to refute the claim. One of the major drawbacks to the theory of reincarnation is that there is no scientific way to understand the link of the memories between the two existential time spans of the individuals (Irwin, 2017). Therefore, in this essay it is seen that the claims of past life memories cannot be refuted or be scientifically proven by anyone. The claims of reincarnations have been coming time and again in the history, and may continue to do so but any argument about them is like an argument about the ghost or gods. These entities exist for those who believe in it and do not exist for those who do not. The truth of these entities cannot be proven and is subjective to individual belief system at present.
