Flame Tests Atomic Emission and Electron Energy Levels AES‚ or atomic emission spectroscopy‚ is a method which chemically analyzes the particular wavelength of a sample element to identify and determine the abundance of this certain element. The wavelength of the atomic spectral line unveils the identity of the element while the emitted light intensity is proportional to the number of atoms in the element. The flame test is also a very effective way to identify an individual element. The color

Calculation Basis of Air Conditioning CO2 Emission 1 Burning 1 kg of standard coal produces about 2.93 kg of CO2 Type and producing area of the coal leads to the difference of heat value and carbon content. 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% =

Sample preparation using microwave digestion was used for mineralization of this plant. Atomic absorption spectrophotometry (AAS) and UV-Visible spectrophotometry were used to quantify metal levels and Phosphorus‚ respectively. Essential oil from aerial parts of P. undulata was obtained by hydrodistillation. The chemical constituents of essential

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

ACKNOWLEDGEMENTS It is usually said that no man is an island unto himself‚ and any man who so lives all by himself‚ without interacting with his fellow men is in the words of Aristotle‚ “either a beast or a god”. Mutual co-operation and interaction form the cardinal feature of human life. The task of writing this report has not‚ in the least‚ been an easy one‚ and it would be axiomatic to add that all the numerous tasks involved could not be have been accomplished successfully singly
