Practical 3 Absorption Spectra and the Beer-Lambert Law INTRODUCTION Electromagnetic radiation can be described in terms of frequency (V) and wavelength (λ). Absorbance is the capacity of a substance to absorb radiation and transmittance (the fraction radiation at a specified wavelength that passes through a sample) is physical properties that all molecules have. The purpose of experiment one was to find the maximum absorbance (λmax) occurred for both bromophenol blue and methyl orange by

His dream was to create such a race that people from all over the world would come to see it. The three largest racing series in Nascar are the Sprint Cup Series‚ the Nationwide Series‚ and the Camping World Truck Series. These series use three types of tracks throughout the United States: speedways

Help Beer Profits 1. “The oligopolistic nature of the market worked‚” commented one manager. What does this statement mean? This statement mean that since the sellers are so few‚ what one Beer seller does in the market can impact the its competitors and the industry. This means that since the industry is dominated by a few firms‚ then the firms that are competing in the market have to take into account competitors’ moves about pricing‚ advertising and output. 2.

De Beers Case Study This case study of De Beers outlines the company’s evolution from its formation in the mid-1800s to year 2000. In these 200 years span of time‚ De Beers was the leader in the mining of diamonds and their leadership contributed to what the industry is today. As the leader in the industry‚ De Beers had large stakes in mining fields in South Africa. Their dominance in the country also meant being socially responsible. At the onset‚ this was difficult to validate because
