Effects of Terrorism Essay Example for Free

Effects of Terrorism Essay Victims of terrorist attacks by the year 1985 was at 816 people, in 2001 the number of deaths rose to 3,295 because of the attacks on the 11th of September, 2001. 2996 people died on this day. More than 1,000 people died because of acts of terror in 2003. Nobody expects this kind of stuff to happen. But since it does happy, people have to live in fear, and worry about â€Å"what if† this happens again. A lot of people are even the government are constantly asking themselves â€Å"are we ready? †. This can happen any time, and any day. There is no way to really prepare yourself since you don’t know when and what will happen next. It is believed that terrorist strike for a couple different reason. There are a lot of people in the world who hate the United States and would risk their life as a suicide bomber. They use murder, kidnapping, hijacking, and bombings to perform these attacks. â€Å"The single biggest threat to U. S. security, both short-term, medium-term and long-term,† President Barack Obama said April 11, is the possibility that terrorists might obtain a nuclear weapon. The second biggest threat to world history’s mightiest military state, it goes without saying, are terrorists without nuclear weapons but armed with box-cutters, rifles or homemade explosives. In order to solve the problem of terrorism , the root of the problem must be found. People start to apply terrorism to certain races, religions, and nationalities because the cause is not exactly known. Doing so and blaming one nation, may make them angry and want to fight back which will lead to terrorism. After the September 11 , 2001 attacks, the government knew that things had to be different. Security almost everywhere was stepped up and there was a lot of changes taking place. If you flew on an airplane before 9/11 and then flew again after, you would definitely notice the difference. There used to be a fairly fast security check out at the airports. Now, there are hours of security procedures that are required before you are able to pass security and board your flight. Simple things such as fingernail clippers could be confiscated because they pose a threat. This isn’t only limited to airports though. When you attend a large event, such as, lets say a football game, you will noticed a high presence of security there too. None of these security measures existed before terrorism. It’s all a matter of cause and effect. Terrorism has been around for a very long time, but has been on the rise in the last 10 years. Nobody knows what causes a terrorist attack. Some people say it has to do with race, nationality, or even religion. If a terrorist doesn’t like the way that a government works, that right there could be another reason. Due to all the terrorist attacks, security almost everywhere has been upped. Terrorism has no warnings, and can happen anytime. It endangers the life of every person in the United States. Since there is no warning, the best thing is to just know what to do when a terrorist hits, and with all the recent attacks, and the security being upped, hopefully we are just one step closer to solving this problem.

Carbon Dioxide In Beverages :: essays research papers

Carbon dioxide is a colorless gas, it has a small but sharp odor and a slightly sour taste. Each molecule of carbon dioxide consists of one atom of carbon and two atoms of oxygen. Its chemical formula is CO2. Carbon Dioxide is about 1.5 times heavier than air. The specific volume at atmospheric pressure (101.3 kilopascals) and 70 º F (21 º C) is 8.74 ft3/lb. Under normal conditions it remains stable, inert and non-toxic. To liquefy CO2 it must be under 300 pound per inch gage(psig) at 0 º F or 838 psig at 70 º F. Above the critical temperature of 87.9 º F, at which all three phases gas, liquid, or solid may exist in equilibrium with one another, CO2 can exist only as a gas, no matter what amount of pressure. When liquid CO2 is cooled to -69.9 º F and the pressure drops to 60.4 psig it turns into dry ice snow. All CO2 existing in the atmosphere is estimated to be 720 x 109. Carbon dioxide makes up about 0.03 percent of the air. Although that is a small amount, plants and animals depend upon it for life. Green plants make their nutrients with it. They mix the carbon dioxide with water to make sugar by a process called photosynthesis. From the sugar, the plants then make starch and cellulose. Animals eat the plants and in getting energy from the food, they produce carbon dioxide and return it to the air as they breathe. Research in Muana Loa and the South Pole showed that CO2 content in the atmosphere has increased from a presumed 250 ppm in the pre-industrial era to 315 ppm in 1958 and to 340 ppm in 1984. If this trend continues the CO2 concentration will reach about 600 ppm in the next century. Besides being produced by breathing, carbon dioxide is formed when carbon-containing materials such as wood, coal, and petroleum products are burned with plenty of oxygen in and around the fire. Carbon Dioxide has found many uses in the industrial world. CO2 is not usually taken from the atmosphere because the concentration is so low. The industrial worldâ₠¬â„¢s CO2 is commercial produced. The CO2 production plant, type CBU, is based on the combustion of oil or gas. The flue gas normally contains sulfur dioxide, which is removed by water and soda lye scrubbing. If combustion is based on sulfur free fuel the soda scrubber can be omitted.

Introduction to Organic Chemistry Essay

Amines are compounds composed of nitrogen atoms bearing alkyl or aromatic compounds. Amines undergo interesting reactions, one of which is with the reaction with nitrous acid producing an azo dye. In this study, the experiment focused on synthesizing an observing the physical properties of Sudan-1. Sudan-1 is of the most common dyes found in waxes, oils and in some food ingredients specifically curry and chilli powder. Furthermore, this study aimed to understand the mechanism behind the synthesis of 1-phenylazo-2-naphtol. To be able to synthesize Sudan-1, preparation of phenyldiazonium chloride solution and ÃŽ ²- naphthol solution were done. Ingrain dyeing was also done in this experiment. The synthesis of Sudan-1 has a two-step reaction – diazotization and coupling reactions. Diazotization is the formation of diazonium salt, meanwhile, the coupling reaction took place when an activated aromatic compound, ÃŽ ²-naphtol was reacted with the diazonium salt, benzene diazonium chloride, to form the azo compound known as the 1-phenylazo-2-naphthol. As a result, an orange-red precipitate was formed after series of reaction. Hence, all the said objectives in this experiment were achieved. Amines are compounds that are composed of a nitrogen atom bearing alkyl or aromatic groups. They are basic and nucleophilic because of their lone pair. They occur both in plants and animals. Amines produces some of the most interesting effects and of the common reaction of aminewith nitrous acid producing a dye[4]. Alizarin, for example is a red dye extracted from madder root used by Egyptians and Persians. However, in this experiment, it aimed to produce a dye commonly known as Sudan-1. Sudan-1 is a lysochrome with the chemical formula 1-phenylazo-2-naphthol. It is a powdered substance with an orange-red color. This azo dye is most commonly found in waxes, oils, and also in some food coloring ingredients – curry powder and chili powder. However, the presence of Sudan-1 in most foods now is currently being banned because it has been classified to be carcinogenic. This experiment focused on synthesizing of 1-phenylazo-2-naphthol which is a two-step reaction. The first reaction is the reaction of aniline with nitrous acid, which is called diazotization and second, the reaction of diazonium salt and beta-naphtol to form azo dye which is the coupling reaction. Figure 1 Diazotization Reaction of Aniline to Produce a Diazonium Salt Figure 1 Diazotization Reaction of Aniline to Produce a Diazonium Salt In diazotization reaction, there is a formation of diazonium salts. This reaction is made possible when a primary aromatic amine is treated with nitrous acid. Then in coupling reaction, the electrophilic substitution reaction of a diazonium salt with an activated aromatic ring formed a azo compound specifically an azo dye.[3] The main objective of this study was to be able to synthesize Sudan-1. Also, it aimed to characterize the azo dye with its most distinguishing physical properties. Furthermore, this experiment also aimed to understand the mechanism behind the synthesis of Sudan-1. Figure 2 Coupling Reaction of Benzene Diazonium Chloride with ÃŽ ² -Naphthol Figure 2 Coupling Reaction of Benzene Diazonium Chloride with ÃŽ ² -Naphthol Aniline was reacted NaNO2 crystals under acidic condition using HCl in a cold temperature. The solution was done in a very cold temperature because the phenyldiazonium intermediate easily decomposes back to its aniline counterpart at a slightly high temperature; hence the temperature of the solution was maintained in an ice bath below 5Â °C. Rock salt may also be added to the ice bath to maintain the temperature. However, in this experiment, no rock salts were added instead constant monitoring of the temperature was done. ÃŽ ²-naphthol solution was used as a coupling reagent in synthesizing Sudan-1. In preparing ÃŽ ²-naphthol solution, ÃŽ ²-naphthol was dissolved in 5% of aqueous NaOH and was also cooled in an ice bath below 5Â °C, this was to avoid the decomposition of the compounds. The main reaction that occurred in the preparation of phenyldiazonium chloride solution was diazotization reaction. Diazotization is the reaction between a primary aromatic amine and nitrous acid at cold temperatures to diazonium salt compound.[2] Figure 1 below is the reaction exhibited by the phenyldiazonium chloride solution. As this experiment aimed to synthesize Sudan-1, two steps are done. The first step would be the reaction of a primary aromatic amine to produce a diazonium salt as seen in Figure 1. The second step, then, is the reaction of the diazonium salt with a strongly activated aromatic syste,l known as coupling reactions. Azo coupling is the reaction between a diazonium compound and aniline, phenol or other aromatic compound which produces an azo compound.[5] In this experiment ÃŽ ²-naphthol couples with the diazonium salt. Figure 2 below shows the coupling reaction of the benzene diazonium chloride with ÃŽ ²-naphthol and having the product of Sudan-1. Furthermore, figure 3 below is the summary of reactions of the synthesis of Sudan-1 in this experiment. Figure 3 Summary of Reactions in Synthesizing Sudan-1 Figure 3 Summary of Reactions in Synthesizing Sudan-1 In this experiment, a filter paper was used to undergo ingrain dyeing. Ingrain dyeing is an irreversible chemical reaction of the diazonium salt solution and the activating aromatic solution. An orange-red filter paper was produced after such procedure. The presence of orange-red color in filter indicates the presence of the azo dye (see appendix for the orange-red filter paper produced). The Sudan dye is synthesized right in the spaces between the filter paper such that they are permanently trapped inside the fiber spaces of the filter paper.[2] After mixing the phenyldiazonium chloride solution with the ÃŽ ²-naphthol solution, an orange-red paste-like solution was formed. Furthermore, the mixed solution was also reacted at a temperature not exceeding 4ËšC for 1-5 minutes. Afterwards, the mixture was also filtered was washed with several portions of water to filter the product, Sudan-1. Recrystallization was also done when the filtrate was steamed bath after dissolving it with 95% hot ethanol. AS a result, orange-red crystals were formed which is the Sudan-1 product. The crystal appeared to be orange-red in color due to the N=N bond present in Sudan-1. The N=N is responsible for the absorption of light thus reflecting a color which is orange-red. The structure of Sudan-1 is shown in Figure 4 below showing the N=N bond of the compound. The N=N is known as the chromophores which are responsible for the color. The –OH group attached in the structure is also responsible for enhancing the orange-red color. The –OH functional group is known as the auxochrome, which modifies the ability of the chromophore to absorb the light.[1] Figure 4 Structure of Sudan-1 Azo-compounds, compounds with general formula Ar-N+=N-Ar-, are coupling products from the reaction of diazonium salts with amines. The general reaction pattern for Sudan synthesis first undergoes diazotization reaction and then coupling reaction with highly activated aromatic compounds. In this experiment, the diazotization reaction of aniline with NaNO2 and HCl yielded a diazonium salt, benzene diazonium chloride. Furthermore, the diazonium salt then underwent coupling reactions with an activated aromatic ring which is ÃŽ ²-naphthol. The coupling reaction yielded an azo compound which is most commonly known as the Sudan-1 with an IUPAC name of 1-phenylazo-2-naphthol. As a result of the reactions in this experiment, an orange-red color of solution was produced. This experiment aimed to understand the reactions that underwent to synthesize Sudan-1; as a result, figure 3 was the summary of reactions. As a physical result, orange-red colored crystals were produced representing the azo compound, Sudan-1. However, some minor errors will not be ignored in this experiment. Some errors like human errors might have affected the results in yielding a pure azo compound. One human error, would be the measuring of the reagents used to yield the said product. Also, the misreading of some measurements may have also affected the results of this experiment. Also, some impurities in the chemicals used will also not be ignore, since this impurities may have led to a not so visible side reactions in the said experiment. After being said and done, all the said objectives in this experiment were met.

Argumentative Essay On Nuclear Waste - 1712 Words

A world filled with uncertainty is already a scary place to live. Murphy’s law only makes that uncertainty destined for disaster where anything can go wrong, will undoubtedly go wrong. The United States has placed itself under the mercy of Murphy’s law, not because of Trump’s threats of war with North Korea, but because it has no safe way of disposing of its nuclear waste. Radiation is a silent killer; if exposed into the environment it could lead to genetic mutations, cancer, and if long enough, premature death. Furthermore, radioactive material can work its way up from the environment to animals, to humans up the food chain nowhere near the site of exposure. We have been complacent in finding a permanent solution to nuclear waste†¦show more content†¦That one percent of waste can be devastating to any ecosystem it is exposed to. Radiation is invisible, it has no scent, it cannot be cleaned by soap, and it should be of concern as much as any disease or virus. The scientific community unanimously agrees that exposure to high levels of radiation is a health hazard. Many people feel unconcerned because they feel it’s not a relevant problem in their lives. However, there are over 71,000 tons of nuclear waste simple in temporary storage at the U.S.’s 104 nuclear reactors (Oliver). Nearly one out of three Americans live within a 50-mile radius of a reactor filled with waste (Oliver). Still many are skeptical remaining ignorant of the potential dangers of radiation exposure. The severity of the damage to a person’s heath due to radiation is based on how much radiation and how long they were exposed to the amounts of radiation. The amount of radiation a person receives is measured in â€Å"rem† and depending on that the health effects could range from no observable health effects, to cancer, to even death (Effects of Radiation). Even a fraction of the amount of radiation to kill a person could cause nausea, fatigue, v omiting, loss of appetite, loss of hair and abnormalities in blood cells (Effects of Radiation). Nuclear waste from a typical fuel rod will still have 2,000 times more rem than the required dosage to kill a person even after 10 years (USNRC).
