"Atomic Weight of Magnesium"

Download file to see previous pages The ChemLab was used to simulate the reaction involving Magnesium and Hydrochloric acid, which produced hydrogen gas, magnesium and chloride ions. By measuring the amount of gas produced, the molecular weight of Magnesium was calculated.
Using ChemLab, 30 ml 2M HCl was added to 300 ml H2O. 10 mg Magnesium was then added to the solution. After measuring the amount of Hydrogen produced, the molecular weight (grams per mole) of Magnesium was calculated.
The calculation of the molecular weight using the weight of magnesium and the amount of hydrogen gas released was facilitated by the used of the balanced equation describing the reaction between magnesium and HCl:
This means that a mole of magnesium needs two moles of HCl to produce a mole of hydrogen gas, a mole of magnesium ion, and a mole of chloride ion. This direct relation is applicable only when the parameter compared is the ...Download file to see next pagesRead More

Methods Used For Magnesium
...Methods Used For Magnesium 1.0 Analytical Chemistry of MagnesiumMagnesium was discovered by a farmer at Epsom in England in 1618, the substance was then called Epsom salt due to its bitter taste and healing power. It was later recognised to be hydrated magnesium sulphate MgSO4. In 1808, Sir Humphry Davy produced magnesium in metal from by electrolysis of magnesia and mercury oxide. In 1831, Antoine Bussy produced magnesium in coherent form and suggested the name magnum, which later turned into magnesium (Avadesin& Baker, 1999). Magnesium is an alkaline earth metal, belongs to second group of s-block...

...on the periodic table. The atomic number for the element is 12 and the average atomic mass of its isotopes is 24.3050. It is a group IIA element (Group 2) also referred to as the alkali earth metals. The most common naturally occurring isotopes, or those that are stable under standard conditions are the three stable isotopes, 24Mg, 25Mg, and 26Mg, although nineteen radioisotopes that range from 19Mg to 40Mg have been isolated; however, these unstable isotopes commonly decay to atoms of sodium or aluminum depending on their weight and composition [2]. Of the stable isotopes 24Mg is the most abundant, accounting for approximately 79% of Earth’s magnesium...

A type of alloys called Wrought Mg alloys have the potential to serve these needs better then the die cast Mg alloys. 1 more benefit of using alloys is “The use of Wrought Mg parts in vehicles will cause weight saving up to an average of 30% compared to Aluminum and 70% compared to steel. Magnesium alloys are in demand now days for the properties like low density, high melting and boiling point, high specific strength, good electromagnetic shielding characteristics, excellent castability and machinability.

Hiroshima: Why America Dropped the Atomic Bomb by Ronald Takaki (pp. New York: Little, Brown and Company, 1995.) In this book Ronald Takaki, a renowned historian, surveys the reasons behind America’s decision to bomb Japan; Was Hiroshima bombed to hasten the end of war or indicate the initiation of the Cold War? Takaki explores the motivation behind the bombings in the context of race and the moral dimension of the act and extracts evidence from top-secret military reports, letters and diaries.

...?(Word count 022 – excluding bibliography) Atomic Bombing Introduction Atomic bombing in Hiroshima and Nagasaki during World War II is a controversial issue. There are some critics who are not in favor of and even condemn such act. For them, it was not the appropriate move to end the war between the United States and Japan in 1945. There were at most 200,000 number of Japanese civilians who were reported to die from that nuclear bombing in two particular places in Japan, Hiroshima and Nagasaki on August 6 and 9, respectively. According to these critics, the death of civilians in the Second World War could remarkably point out the inhumane approach involved with that bombing together with other...

This short editorial focused in the social responsibility that the scientists developing weapons of mass destruction have. Mentioned in the article is that fact that the decision to use a major weapon, such as the Atomic Bomb, have largely been left up to the government, specifically the legislative body. As a result of the attacks on Hiroshima and Nagasaki, however, the public is increasingly becoming involved in the debate. This editorial makes it a point to mention that, if a third world war is to be avoided, then the public must become even more involved. The author... of this...

...and technology. The world wars made it clear to man that science was something that could be used for causing unimaginable misery on mankind. The atomic bombs that were dropped in Hiroshima and Nagasaki proved to even those who were not directly affected by the destruction the power of such bombs. There was thus, a fear of atomic power as something that could trigger off apocalypse or the end of mankind as a species. This fear was then expressed through movies such as The Day the Earth Caught Fire and The Day the Earth Stood Still. These movies were made in the wake of the world wars and the effect of these wars and the incredible human loss that they caused can be seen in them. The Day the Earth Caught...

Atomic Spectra
...Part I: (20 pts Typed Introduction Section Print one hard copy to bring to lab and submit to turnitin.com. Part II: (15 pts Worksheet General a. (2 pts.) Why do elements and ions exhibit line emission spectra? (not continuous spectra) when an element or its compound is volatilized on a flame the electrons in the atom are excited, and jumps to the higher energy orbits. Here these electrons are unstable and try to return to their initial position. As the electron return back to its lower orbit the photon of specific wavelength is emitted, and the wavelength depends on the difference in energy between the two states. Now the spectrum of these wavelengths (radiations) when observe against the dark back ground gives us the...

Magnesium is a greyish-white metal that burns with a blinding glare. The atomic number of Magnesium. In the 18th century, the French chemist Antoine Lavoisier was busy performing very many combustion experiments. After some time, Lavoisier realized that even though the reaction characteristics of the materials varied the total mass of the products was similar to the total mass of the reactants. Lavoisier summarized his observations in the law of conservation mass, which states...
