September 8, Metals and Corrosion Experiment Introduction A metal is defined as substance containing high electrical conductance, which has luster and is malleable. Metals loose electrons forming positive ions known as cations. There are various properties of metals. These properties can either be chemical properties or physical properties. On the other hand, corrosion of metals is the process by which the surface of a metal or its related materials deteriorates as a result of the metal losing electrons and remaining with positively charged ions. Reaction of Iron III oxide with water in presence of air results in the formation of iron II oxide which is referred to as rust. This is an indication of corrosion in the given metal. This experiment’s main purpose is the determination of the properties of metals and to find out the corrosive effect on metals.
Metal Properties
The properties of the metals, iron, brass and copper, were compared. This involved comparing the conductivity of both iron and copper, Hardiness, and brittleness. The observations were made and recorded. In testing for conductivity, the metals were heated and time taken to heat up observed. In comparing for brittleness, the wires of the respective metals wire bent and the number of times the wire was bent before breaking observed.
Data and Observations
After heating copper and iron to test for conductivity, copper became hotter faster as compared to iron. When comparing the conductivity of copper and brass, copper become hotter faster than brass.
Comparison of the hardiness between copper and iron resulted in iron being harder than copper. On comparing the hardiness between copper and brass, it was found that brass is harder than copper. Also, it was found that alloys of these metals are harder as compared to the pure metals.
The number of times copper wire was bent before breaking was two. On the other hand, the number of times iron wire was bent before breaking was one.
After corrosion test was done on all the substances, i.e. copper, brass and iron, it was found that both copper and brass were corroded and copper was resistance to corrosion.
Copper has a higher conductivity as compared to iron and brass. This is due to the fact that copper contains a large number of de – localized electrons. These electrons move freely and as a result facilitate the conductivity process.
From the experiment, it’s clear that iron is harder than copper. This is due to the strong covalent bonds which exists between the iron molecules making it to be harder than copper. Comparing the two pure metals with its alloys resulted in the alloys being harder than the metals. On brittleness, iron was found to be more brittle than copper.
Iron and brass was found to be easily corroded as compared to the pure copper. This was due to the presence of iron III oxide which gets oxidized to iron II oxide, and this causes rust.
It can be concluded that copper has high conductivity as compared to iron, copper is more corrosion resistance than iron and iron is more brittle than copper. The alloys of the metals have enhanced properties as compared to the pure metals. Finally, Copper was found to be corrosive resistant as compared to iron and brass. Read More

...?General How is depreciation affecting the housing market? Depreciation is affecting the housing market considerably because now the housing market has come down and the people have started to fear for the property that they have within their folds. Depreciation affects the housing market by lowering down the price substantially which means that the prior market rates are not applicable anymore and the fluctuation has essentially brought about a change in the way people view the housing market in essence. This depreciation takes place over a period of time due to wear and tear, age as well as physical deterioration. Indeed depreciation is an expense and the housing market has become the target of this problem without any doubt... How is depreciation...

Akashi- Kaikyo bridge (Pearl bridge), Japan

...Akashi- Kaikyo bridge (Pearl bridge), Japan Seventeen long-span bridges, including ten suspension bridges, five cable-stayed bridges, one arch bridge, and one truss bridge, connect the main island of Honshu with the southern island of Shikoku in Japan. The Akashi Kaikyo bridge across the Akashi Strait, perhaps the longest suspension bridge in the world, is one of them. It forms a part of the 81-kilometre-long Kobe-Naruto highway and links Maiko, in Kobe, and Matsuho, on Awaji Island. The Akashi Kaikyo Bridge is known in Japan as the Pearl Bridge. Before the bridge became operational, the people had to mainly depend on ferry services to travel between the islands. The ferry travel was uncertain and rather dangerous as the area often...

...NATIONAL SECURITY STRATEGY of Affiliation NATIONAL SECURITY STRATEGY There is need to embed moral values and principles in in an overall national security strategy. America was found on a number of values and principles that are deeply enshrined in its constitution. Key amongst the values is the moral responsibility, first to her citizens, then to the rest of the world. In emancipation proclamation, Abraham Lincoln calls for equality of treatment of all men regardless of race, gender, religion, place of origin, or social status. Similarly, in pursuit of national interests, the American values advocate for justice and equality based on the internationally recognized laws. The same applies to President Eisenhower’s in his farewell address... SECURITY...

Position paper

... Colorado Fuel and Mine Company Colorado Fuel and Mining Company was seen as a political dictator in southern Colorado. This was so, because; it had a sort of mighty power in the whole state. During the strike most workers accused Colorado Fuel and Mining Company of ignoring the promise of an eight hour day. Further, they felt that they were forced to vote in accordance with the wishes of the mine superintendent and that they were beaten and discharged for voicing they complains (McGovern ,15). However, Colorado Fuel and Mining Company dismiss the accusation stating that things would get back to normal after the excitements the workers had. (,McGovern, 16). The company mine was sprinkled only when the dust became thick enough to prevent... Colorado...

...Corporate Governance Introduction Corporate governance is a practice that aspires to assign business resources in an approach that capitalizes on value for all stakeholders of the company. They are the shareholders, financier, investors, workers, clients, trader, contractors, environment and the society at large and they stand at the driving position to account by assessing their judgments on precision, inclusivity, justice and accountability (La Porta, et al., 2000). The World Bank classifies governance as the implementation of political power and the utilization of institutional properties to direct societys affairs and problems (Raut, nd).
