Bromine Element Essays - Chemistry, Matter, Nature,
Bromine Element The element Bromine, is a red liquid which is explosive at room temperature and has a red brown vapour. It has an atomic number of 35 and an atomic mass of 79.909. The melting point of Bromine is -7 deg.C and the boiling point is 58 degC with a relative density of 3.1. Bromine is a volatile dense mobile, that is a reddish brown liquid, which quickly gives a brown toxic valour with a disagreeable irritating odour. It combines directly with most elements although heat or a reactant is often neccessary to start some reactions. Hydrobomic Acid and Hypobromous Acid is a mixture that is formed when Bromine reacts with water. Oxygen is liberated by Bromine when the resulting solution is heated or exposed to strong sunlight. A solution to Bromine in water is called Bromine Water, which is used as a test reagent in organic chemistry to identify unsaturated compounds. Bromine resembles Chlorine in many of its properties, but is less active. Because of its reactivity, Bromine does not exist in the free elemental state in nature, but small quantities are combined in many silver ores. Bromine salts are found in seawater and in the salts deposits in Strassfurt. Compounds of Bromine also occurs in marine animals and plants. Bromine is used in a wide range of industries. It is used in the manufacture of 1,2-DibromoEthane, CH2BrCH2Br, which is used as a petrol additive to prevent lead being deposited in the cylinders. The manufacture of compounds used in photography and the manufacture of dyestuffs and drugs is another use of bromine. Bromine is used in the analytical laboratory in testing for unsaturation in organic compounds, where it adds across the multiple bonds of unsaturated compounds.

Essay Sample on Urbanization for Canada
Essay Sample on Urbanization for Canada Urbanization is a big part of the modern world, without it, we would all be lost. While countries are growing at a rapid rate, the once ââ¬Ëoldââ¬â¢ cities of the past are expanding onto previously un-occupied lands and even sometimes creating new towns and cities. Suburbs of cities spring up all over the world all the time, and populations grow with them. Major areas or cities of countries are usually hubs of economic significance, and help shape the country into itââ¬â¢s true self. These areas help the country grow, and provide hundreds and thousands of jobs and careers for the citizens. Canadaââ¬â¢s largest hub is Toronto, but all major Canadian cities have their own pledges to the Canadian and world economy. Iââ¬â¢m going to dab a little bit into these metro areas, and explain what they do for Canada. Urbanization is essential for Canadaââ¬â¢s economy because of the extensive growth and demand for commodities involved. How is Urbanization tied into Canadaââ¬â¢s Metropolitan Areas? How does it affect the people that live in them? These questions are probably common, and need to be tended to. Urbanization is what makes Canadaââ¬â¢s metro areas metro; people tend to look at most countries and see cities they think just appeared out of thin air. Urbanization is what shaped our cities into what they are today. Long ago, people didnââ¬â¢t live in cities; they tended to live in rural areas with the odd exception of a city or town of significance because of its central role in everyday life. Usually cities before the year 1200 were small with no more than 30,000 inhabitants. These cities were built because they were usually a capital, or a major trading area with markets and bazaars. Over time cities evolved to become walled and protected, and that too ââ¬Ëstoppedââ¬â¢ the growth of the cities. War, droughts, disease, all took a large toll on shaping cities in the past, and once a prosperous age came, people began to multiply. Once populations exceeded the cityââ¬â¢s own capacity, suburbs were born. W e see this today in many medieval-like towns and cities. Paris for example was once small and busy, now parts of the city walls are gone and roads were constructed to take people to new parts of the city. Paris has well over 9 million people now and is extremely busy. We also see this in Canada; the only walled North American city now exceeds its capacity, and walls were torn down to make way for a larger city. This city is Quebec, and one of Canadaââ¬â¢s largest metro areas. Canadian cities are some of the fastest growing cities on the globe because they are so young. Most were founded between 1690 and 1840, which is very young compared to many African, Asian and European cities, which sometimes date back to before Christ. Today Canada hosts a wide variety of urban sprawl, which is housing that, is put up quickly to house a lot of people fast. An example of urban sprawl can be found in Windsor Ontarioââ¬â¢s: The Villages of Riverside, Forest Glade, Green Park, and Blue Heron Point. The highest quality of these urban sprawl lands is Green Park, followed by Forest Glade, Blue Heron Point, and finally The Villages of Riverside. Urban sprawl has its pros and cons, pros being, that people can move in fairly quick, easily afford these housing developments, and live away from the main city. Cons are, usually these housing developments are put up too fast degrading the overall quality of craftsmanship, making the area a low income ââ¬Ëslum.ââ¬â¢ (However, this is not always the case). Canadaââ¬â¢s largest cities are usually quite dense and populated with more than 100,000 people. These cities were once trading posts, forts, or plain old rural farms. Today, with Canadaââ¬â¢s population of almost 32 million, 78% live in urban areas. If thatââ¬â¢s not urbanization, then what is? The remainder 22% live on farms, or small villages. A settlement with a population over 3,500 is considered to be an urban area according to Canadian standards; anything less is rural.

Current Event Review Article Example | Topics and Well Written Essays - 250 words
Current Event Review - Article Example However, he believes that the federal and judicial agencies are corrupt in protecting the whistleblowers and, instead, allow the bureaucracy to avenge those who have blown the whistle. In fact, those who endorse the corrupt activities and are involved in its operations are promoted for their work. The prevailing conditions for whistleblowers are very discouraging for individuals with moral spirit to come forward and uncover corrupt activities. For those, who can gather enough strength to voice out the misconduct, the ineffective laws are bound to destroy their professional careers and, possibly, their lives too. They will either be forced to leave the organization, or face a low-profile transfer; they may even be disregarded, or ridiculed, and threatened by their colleagues. Even in the U.S., a nation that proudly boasts justice, equality and freedom of speech, the judicial agencies ensure that a whistleblower is punished for being morally strong and honest. These conditions, on the contrary, are very encouraging for institutions to commit crimes. With an ineffective system, businesses and institutions can be corrupt and easily get away with it. The business can be harsh on any employee who intends to or already has blown the whistle. However the extent to which this is possible is debatable since the article talks about federal bureaucracy benefiting from a federal judicial system. In the case of other businesses or institutions it would be important to see the interests of the judicial agency within a particular scenario and the benefits they can get from it. Nonetheless from an institutional point of view a whistleblowerââ¬â¢s lifelong savings can be seized through a lawsuit while institutions can spend millions of dollars in a lawsuit. Unless the government agencies become honest and work for the greater interest of their people, whistleblowers will be forced to follow the system whether it is wrong or right. The government needs to
