Emission Spectroscopy The purpose of this lab was to see that when elements are heated‚ they may enter and excited state. We proved this by doing a flame test. During Part A‚ we used a spectroscope where all of the colors are arranged for you; whereas in Part B‚ we could see and make the colors ourselves and get a more accurate reading of the flames. We had specific elements we were told to put on the wire loop‚ and when we did that we saw different color flames come out of the Bunsen burner. That

Emission Spectra & Flame Tests Intro The emission spectrum is used in modern chemistry to help further studies of wavelengths and the spectrum. When a metal in a compound reacts in a flame and produces a color‚ it helps to show the strongest color in the emission spectrum. The purpose of performing these operations on the flame was to see how different metals would react. Using a spectroscope‚ it is possible to observe the line emission spectrum produced by sunlight‚ artificial light‚ and

to calculate wavelengths of line emission spectra while also using this data to determine the unknown mixture of the flame emission procedure of the experiment. The original hypothesis was that the spectroscope would show multiple different line emission spectra in which the ΔE would be negative there was an emission of light as the electron’s decreased in electron transitions. This hypothesis was proven correct‚ as well as‚ the unknown mixture is predicted to contain iron III‚ copper II and potassium

Journey to the unkown The purpose of Chris McCandless’s journey was for him to find himself through the simplicity of nature. Growing up‚ his parents were controlling and when he graduated from college he set out on his journey. Chris took his car and went north. In the book Into the Wild‚ Jon Krakauer explains his thoughts and reasons behind Chris’s choice to go into the wild. “McCandless went into the wilderness not primarily to ponder nature or the world at large but‚ rather‚ to explore the inner

Characterizing the Most Extreme Emission Line Galaxies Spring 2014 UROP Proposal Ian Jaeger Background During the first 379‚000 years (redshift z = 1089) after the Big Bang‚ the matter of the universe consisted primarily of free protons‚ electrons and photons. After the matter had cooled and spread out‚ these particles combined to form hydrogen and allowed the photons to freely travel without interacting with free electrons‚ forming what we know of today as the Cosmic Microwave Background (CMB).

Short Film: Love directed and written by Martin Jose Ponferrada Summary: Two Ends of a Spectrum The film takes place in two timelines and involves two couples from different continents. The Australian couple‚ Walt and Ruth‚ lives in the present and are bickering on account of the husband’s obsession to catch flies that to his wife’s dismay‚ resulted to the neglect of his household chores. The Filipino couple lives in the memory of the husband‚ Jessie. He remembers his wife‚ Appollonia‚ as an

We apply the Conceptual Framework to the components of cap-and-trade programs in section 3.1. Section 3.2 describes the resulting accounting treatment‚ including income statement effects‚ of cap-and-trade program rights and obligations that is implied by the Conceptual Framework. 3.1.

In China‚ usually the carbon content of coal is from 45% to 85%. In China‚ it is provided that the heat value of standard coal is 7‚000 Kcal/kg‚ carbon content is about 80%‚ CO2 emission of the 1 kg standard coal should be: molecular weight of CO2/ atomic weight for the element of C * 80% = 44 ÷ 12 × 80％=
