INTRODUCTION: In atomic spectroscopy the samples are vaporized at 2000-8000k. The process of this involves two steps ‚ one is atomization of sample and the other is absorption of light radiation from light source. The atoms in the vapour are measured by absorption or emission at characteristic wave lengths. The main usage of this was to detect one element from another in the complex sample which has taken ie.‚ it has ability to perform multiple element analyses. Absorbance should obey Beer’s law

the nuclear model of atomic structure. He suggested that an atom consists of a central nucleus (where most of the mass of the atom is concentrated) having a positive charge‚ surrounded by moving electrons carrying negative charge. Geiger and Marsden carried out an experiment to verify his proposal. The Geiger/Marsden a Particle Scattering Experiment 1. The apparatus is illustrated in the diagram below. | 2.

novels from all eras of time. Frequently feelings dealing with deceit –lying or jealousy- creates anger in an individual leading into irrationality. However‚ can a simple trick or lie for the sake of entertainment or flattery allow deception to be justified? Robert Southey once said “All deception in the course of life is indeed nothing else but a lie reduced to practice‚ and falsehood passing from words into things.” (Southey 133) If we look through the famous works of today‚ we notice deception

He wanted to prove me that the government has something to do with the attack and also is manipulating the media with fake or inaccurate information so we can believe whatever the media says. When I first heard about the attack on the media I was so sure that the government did a good job but Manny showed me a video as evidence to reinforce his statement. Now I am standing in the middle of a circle of accurate and inaccurate information‚ but unfortunately I can’t decide who to trust. The media

Is there such a thing as justified killing? Many would argue that the killing of another individual is by far one of the worse crimes that can be committed. Though under certain circumstances such as capital punishment‚ or to kill in self-defense‚ justified killing is okay. These options are only acceptable if there is no viable alternative to doing so. Everyone has the right to live‚ and once someone decides to kill another individual then they should lose that right. They don’t deserve to have

expansionistic than it had been for the past few decades. There was apparently a hunger for foreign conquest. The conflict with Spain derived mainly from the American desire to help the beleaguered Cubans with their independence from Spain. Americans wanted the war‚ which could well have been avoided‚ but they had little understanding of what the reults of the war would be. I believe American entry into the Spanish-American war was not justified. In September‚ 1895‚ came the event which changed the course

Vietnam‚ although not technically considered a war was an extended conflict that still had to be justified to an American people. The Tonkin Gulf Resolution was the identification of this extended conflict and was declared by Congress in 1964 making this conflict official. This resolution was justified because it was declared by a competent authority and was seen as being the best thing for the American people at the

The goal of this experiment is to determine the enthalpy of combustion of naphthalene by means of a bomb calorimeter. First‚ the bomb calorimeter was standardized using benzoic acid and the average heat capacity of the bomb calorimeter was calculated to be 10.60.3205 kJ/K. From that‚ the These results show that heats of combustions of unknown substances can be determined via bomb calorimetry.
