Colors of Metals Abstract The experiment about flame color of metals demonstrates how electrons jump into their excitedstate from their ground state as it came in contact with heat. As it return to its lower energy state‚it emits the absorbed energy in the form of light. A platinum or nichrome wire was dipped into aconcentrated HCL and was heated to clean it. The wire was dipped into different salt solutionsand heated in order to determine the metallic ion’s color and wavelength. Metal ions emitting

carry out the ideal form of civilization. In this paper‚ I argue Plato’s Allegory of the Cave justifies the need for a royal lie found in the Myth of the Metals‚ for the royal lie serves as an instrument towards achieving the ultimate polis. I examine this claim by describing and analyzing both the Allegory of the Cave and the Myth of the Metals‚ as well as depicting the philosopher’s challenges and the royals lie’s instrumental purpose. Plato’s Allegory of the Cave starts in a world where men are

I interviewed Ms.Pohan my english teacher‚ because she was fascinated by war movies and how different wars are depicted and was always fascinated by war movies. She said that her favorite movie based on the Vietnam war was Full Metal Jacket which she watched three times‚ once in highschool‚ once in college‚ and once in her twenties. She described the movie as unsettling with brutal honesty‚ saying that the movie does not tell you how to feel about what you are watching‚ creating

Ironically it was Cimino who reminded Stone of nothing he experienced in Vietnam‚ and talked him into resurrecting “Platoon”. Stone portrays the war as more of a conflict between American soldiers internally rather than a conflict with the Vietcong. Platoon tells the story of Vietnam from the point of view of a naïve young soldier. The first thing he sees when arriving is rows of bodies being readied to be ship back to the United States. He finds out that other soldiers don’t associate with the

the Reactivity of Metals Aim: To prove the arrangements of the metals (Na‚ Ca‚ Mg‚ Al‚ Zn‚ Fe‚ Sn‚ Pb‚ Cu) according to the reactivity series. Background Information: By using various experiment‚ the reactivity of the metals can be deduced by the observation of the reaction. Hypothesis: Metals with low ionisation energy will lose their their electron more easily providing a more vicious and obvious result‚ as compared to the metals with higher ionisation energy‚ as the metals with lower ionisation

’’? Describe what metal speciation is. How do the master variables of the environment relate to speciation? Why is speciation important in contaminant transport and in biological contexts? If you had to pick a third “master” variable‚ what would it be? Why is chemistry vital to understanding biological systems? Species refers to the form that a metal takes in the environment. This form can be a cation (ex: Fe2+) or anion form (ex: N3-)‚ or just a bonded form (ex: Fe2O3). Metal speciation‚ then‚ refers
