Element Origin and Use
Everything we know about life comprises of basic chemical elements – from the chairs we seat on and the beads we sleep on, to the clothes we wear and the medicines we take, and more. While some chemical elements are rare, others occur in abundance. For this discussion, I will concern myself with Aluminum, one of the elements listed in the Periodic Table of Elements. Assigned atomic number 13, aluminum is denoted using symbol Al and is identified as a poor metal in elements.wlonk.com. According to Krebs (2006), it is not possible to naturally find aluminum in its pure form. This is more so the case given that in its pure metallic form, it is very reactive – most particularly with oxygen.
Aluminum, as the Royal Society of Chemistry - RSC (2017) points out, was discovered in 1825 by a chemist of Danish extract known as Hans Oersted. However, as the society further observes, it was known that aluminum oxide, as early as the 1700s, contained a metal. All endeavors to extract this metal, however, failed until Hans developed a never tried before method to extract the metal (albeit an impure form). The method involved heating aluminum chloride with potassium (RSI, 2017). The extraction...
These include the excavation of bauxite ore, recovering alumina from the ore via a refinery process, and producing aluminum by smelting alumina.
Amongst all the chemical elements found in the periodic table, Aluminum remains one of the most widely used – as an alloy or in its pure form. It also retains its utility in a number of other compounds. As a matter of fact, aluminum only comes second to iron in terms of widespread usage. Being a rather versatile metal, Krebs (2006) points out that aluminum is mostly used in construction. Due to it being lightweight, despite being rather strong, aluminum is used in aircraft construction. Steel, being too heavy would be an unlikely raw material to be extensively used in aircraft manufacture. It is for this same strong/lightweight combination that aluminum is used in motor vehicle design and manufacture. In an attempt to save on battery poser, electric motor vehicle manufacture companies could also favor aluminum…

Monopolies and Trusts: Appropriate Areas for Government Intervention? Capitalism is the economic system that has dominated the United States virtually since the day of its independence. A social and economic system based on the recognition of individual rights; capitalism demands that owners' rights to control, enjoy, and dispose of their own property must be respected. In a capitalist system, the purpose of government is to protect individual economic rights, and to make
On December 14, 2004, Germany was told it must "introduce a system that allows drinks makers, including beer and soft drinks producers, to do business fairly across Europe. Germany must giver drinks makers a longer period to prepare their businesses for complying with the new system, and to make sure consumers can recover their deposits in a far wider variety of drop-off points (unknown)."

Causes of Chronic Bronchitis in Workers This review shows the literature and research available in the issue of respiratory diseases and the various occupations. The review shows that there is a pressing need to evaluate and conduct research in the known areas like coal, cement, and pesticides, but alarmingly agriculture and other industries have also to be included. It is not only the factories that are hazardous. There are arguments to show
Three test launches in September failed miserably, but by October, the crew believed they were ready to test (Green and Lomask, 41). However, on October 4, 1957, the Soviet Union shocked the United States and the world by successfully launching Sputnik 1, into orbit around the Earth, becoming the first nation to launch an artificial satellite into orbit, and pushing them to the front of the now active Space Race
U.S. INVADED IRAQ IN 2003 Why U.S. Invade Iraq 2003 invasion of Iraq has a number of forceful effects that relate to the influence of the 9/11 occurrence in the country. The then U.S. president who happened to have been President Bush pushed for the U.S. invasion of Iraq amidst the actions that Saddam had done to the U.S. In most avenues of performance, it is clear that the U.S. attack
