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

The 13C NMR spectrum was useful to help finding the structure of the unknown. It showed six different signals in the spectrum. Signal 1 had an observed peak value of 19.242 ppm‚ and its peak calculated value was 19.1 ppm. This signal was first to most upfield and shielded in the spectrum because of the high electron density of carbon. This signal was agreed to a literature value for a CH3 group between 5-30 ppm. Signal 2 was branched to signal 1‚ and had the same value‚ but it was agreed for the

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％=

3. Accounting Framework for Rights and Obligations of Emissions Reduction Programs The FASB’s Conceptual Framework provides guidance to standard setters for establishing authoritative guidance. 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.

State the principle of triple beam balance A beam balance measures mass as opposed to weight‚ so the mass you weigh will be the same on the moon as it is on earth. Gravity is taken out of the equation‚ unlike a spring balance that measures weight and would measure an article to be 1/6 of the weight on the moon as it would be on earth using the same spring balance that relied on gravity. The principle is that of moment‚ or turning force/torque)‚ calculated by force x distance. Fundamentally‚

With my research and my visit to the local Clean Air Car Check site‚ I have compiled information that will prove valuable. I will define emission pollution and the major contributors. I will answer the why we have to emission test. I will also take you through the testing process

Emission Control Techniques 1. INTRODUCTION The need to control the emissions from automobiles gave rise to the computerization of the automobile. Hydrocarbons‚ carbon monoxide and oxides of nitrogen are created during the combustion process and are emitted into the atmosphere from the tail pipe. There are also hydrocarbons emitted as a result of vaporization of gasoline and from the crankcase of the automobile. The clean air act of 1977 set limits as to the amount of each of these pollutants
