The Element Calcium essays

The Element Calcium essays Calcium is an element that is very important to everyday life. Its important to our bodies and our universe. Its more than a milk mustache or white teeth. Calcium is in fact essential for the make of bones, teeth, shells and leaves. Calcium is fifth in abundance in the earths crust. Calcium is the mineral in our bodies that make up our bones and keep them strong. Ninety nine percent of the calcium in our bodies is stored in our bones and teeth. The remaining one percent is in our blood and soft tissues and is essential for life and health. Without that one percent of calcium our muscles would not contract normally, our blood would not clot and nerves would not carry messages. Calcium was discovered in 1808 by Sir Humphrey Davy. When calcium is exposed to air, it forms a white coating of nitride. It is found mostly in limestone, gypsum, chalk and fluorite. Gypsum is dry wall and plaster. Calcium is used as a reducing agent in preparing other metals. At room temperature calcium is found to be at a solid state. Calcium is important to me because my body contains 908.908 grams of it. Calcium reacts with water and burns with a yellow and red flame. It is a silvery white color and its classification is metallic. Calciums group name is the alkaline metal. Calcium is also used in vacuum tubes as a getter, a material that combines with and removes trace gases from vacuum tubes. Calcium obviously plays a very important role in our lives. It is very essential for us to live, affecting our bones, teeth, blood and health. It is important to our environment creating other chemicals and things that are useful to us. Calcium is in great demand by a number of industries, and is essential for life. ...

Turn Water Into Liquid Gold With an Alchemy Experiment

Turn Water Into Liquid Gold With an Alchemy Experiment Mix two clear solutions, wait, and watch the liquid turn to gold! This is a simple alchemy project or chemistry demonstration, based on early attempts to make gold from base metals. Materials Solution A 1 gram sodium arsenite50 ml water5.5 ml glacial acetic acid Prepare Solution A by stirring the sodium arsenite into the water. Mix the glacial acetic acid into this solution. Solution B 10 grams sodium thiosulfate50 ml water Prepare Solution B by stirring the sodium thiosulfate into the water. Lets Make Liquid Gold! Pour one solution into the other. The clear solution will turn gold after about 30 seconds. For dramatic effect, keep track of the time and command the solution to turn into gold. You can even use a magic word if youd like. The Chemistry Behind How It Works There is a delayed reaction between the acid and the sodium thiosulfate to release hydrogen sulfide gas. The hydrogen sulfide reacts in turn with sodium arsenite to precipitate tiny crystals of golden arsenious sulfide, which is also known as arsenic trisulfide (As2S3) or orpiment. Both Western and Chinese alchemists experimented with orpiment to try to make gold. Although the mineral can be made to appear metallic under certain conditions, the compound does not undergo any reaction that changes either the arsenic or the sulfur into gold. Still, its a striking demonstration!

Explain how equilibrium is detemined in the keynesian income Essay

Explain how equilibrium is detemined in the keynesian income expenditure model. Use this model to examine the impact of a fall in government spending on the eco - Essay Example Given this rigidity of wages and prices, equilibrium output therefore is determined by demand. The aggregate effective demand is composed of planned real aggregate consumption expenditure (C), planned real aggregate investment (I) and real aggregate government expenditure (G). Real aggregate consumption expenditure is assumed to be a function of real aggregate output (Y) such that if Y rises C also rises but less than proportionally. The equilibrium is attained at that level of income or real output, equal to the effective demand. In the diagram above, the effective demand curve (obtained by vertically summing up C(Y), I and G) intersects the 45 degree line for the level of real aggregate output Y*. Thus Y* is the level of real aggregate output that satisfies the demand supply equality. The intersection point between the effective demand curve and the 45 degree line is referred to as the Keynesian cross. Now if there is a decline in government spending (G) given everything else remains unchanged, the effective aggregate demand will fall for each level of real output. Suppose G falls from G0 to G1. Therefore, the effective demand curve will shift downwards. Therefore the newer intersection point with the 45 degree line shall be to the left of the initial equilibrium point. Y** is the new equilibrium level of income which is lower than Y*. As a result of this decline in the level of real output, there will be a fall in employment as well. As government spending falls, there is a reduction in the effective demand. This reduction causes real output to shrink. This decline in real output again leads to a fall in real aggregate consumption expenditure which in turn reduces effective demand again. This again reduces real aggregate consumption expenditure and so on. However the magnitude of the second fall shall be smaller than the first one due to the non-proportional dependence of consumption on real income. Therefore, as a

Topic in IR - Essay Example Adam Smith opposed this communist theory and instead advanced the capitalist model of development. The Cold War, after the end of World War II saw a resurgence of this theory, with the capitalist economies and communist blocs advancing the theory of modernization, but within the framework of their ideologies (pg.17). Modernization involves five stages since all countries are at one of the development stages, that comprise of traditional society, transitional stage, take-off, drive to maturity and high mass consumption.(Rostow.W.W.1960), In its earliest forms, modernization had brought together masses of people leading to the establishment of either a democracy, communism or fascism. Modernization has shown people that strong democratic institutions lead to socio-economic development and cultural changes, which in turn lead to individual freedom and gender equality- all of which create a society whose main objective is to ensure human emancipation. The rise in self-expression makes society people- centered, and leads to the concept of freedom of choice. Modernization theory has thus created conditions conducive to the humanistic transformation of society, which is its biggest asset. Economic development is the avowed goal of all societies and ideologies. The development of a nation and its place on the larger world stage is determined by the economic strength that the nations wield. This development can be promoted through democratic means as also by creating an authoritarian regime. The modern world swears by the advantages of a democratic set-up, but the success rates of economics thriving under authoritarian rule cannot be ignored. When we put the economies of South-east Asian nations under a scanner, what projects forth is a kaleidoscope of nations, governed democratically as well as by authoritarian regimes. While all democratic economies are performing extremely well, authoritarian nations too show a remarkable vibrant economic

Enclosed in description - Assignment Example Forms are abstract and do not change over time. Shields commenting on this states that â€Å"Forms are objects of knowledge, and since knowledge requires stable, unchanging objects, Forms must have these attributes† (Shields 87). 2. The fact that Socrates does not follow Crito’s advice regarding escape from jail and execution is an indication of the man’s strong conviction regarding justice. He sees escape as morally unjust. It is another matter whether Socrates is guilty or not. According to him it is not right to go against the law. Doing a wrong to correct a wrong is not right. It is equal to the concept of ‘an eye for an eye’ and escaping will result in a great man going against justice. It is not correct to provide such an image (of moral injustice) to the public. Escaping will result in such an image. Crito fears shame because unless Socrates escapes, the public will think that friends (of Socrates) had done nothing to save the philosopher’s life. 3. According to Socrates, an expert is a person who should deliver his goods or advice without contradicting oneself. Morality should also be an essential element. The many cannot really do anything good or bad. The problem with going along with the many is that it can corrupt the morals and sense of justice within a person. The many in this context is the large number of people who want Socrates to escape. But the moral expert would not advice such an act since it would be against justice. This is precisely what Socrates wants Crito to understand. 4. It is not the size of the state that matter, but the strength of the reason for which it was created. The people should work towards upholding that reason and should obey each and every direction given by the state. They may even have to die for it. No individual can survive alone and can do so only under a state’s rule. The state has the power to make individual

Why might we consider globalization to be generated Essay

Why might we consider globalization to be generated - Essay Example Globalization is a big word today and one that has changed the way we look at and understand things around us. What is actually globalization What do we understand by this word Globalization is simply the predisposition of the economy through business, knowledge through technology and thought through philosophy to spread globally. Globalization can also mean the process by which this happens. This term is almost synonymous with intertwining of markets and economies without any consideration for physical border or legal restraints. One of the best examples that jump into my mind is the McDonalds. What better example of globalization Waters1 (1995) describes globalization as 'a social process in which the constraints of geography on social and cultural arrangements recede and in which people become increasingly aware that they are receding'. Ideally it is believed that globalization is the means to create a global positive impact upon the poor and the poverty in general by opening the doors to availability of a host of opportunities and resources which would have, otherwise not been available nationally. The downside is that globalization seems to profit the rich more and the poor less, thus widening the gap further. It is true that globalization actually means the broadening of global linkages, while also impacting upon the social and cultural dimensions of the global society, hence propagating a one-world-citizenship which has one economy, one culture and one social order. Ecumenically globalization's definition would be complete with the above classifications. But there are many inroads in the understanding of the term. This is the process with which the poor countries can think of modernization and global competition, enhanced living standards, and work opportunities; on the other hand this very same process is the one which can destroy economies by sudden influx of foreign capital, can destroy marginalized workers livelihood and destabilize national banks. Hence, globalization literally is like a coin - with two very separate sides. When we think of globalization impact on gender, we need to understand first of all what is defined by 'gender'. What is gender Gender is basically the terms that is most commonly used for 'women'. It is mostly used as social term than biological one. Gender as a term is closed to the definition of anything that refers to women in a social connotation. Now let us think about globalization vis--vis gender. How has globalization impacted gender Is globalization gendered Should it be, in the first place Should it not be This essay is trying to look into a few aspects of globalization which impact women and thereby deduce whether globalization is gendered or not. Gender inequality in particular can create very confusing effects which however are able to highlight the fact the there is a strong connection between poverty and gender. UNDP (1999) has statistics with which you cannot argue. Inspite of the common belief, poverty has actually grown by leaps and bound in the last 10-20 years;
