Beer’s Law And Calorimetry Beer’s Law And Calorimetry Adriane Bellard Ocean County College Beer’s Law is also referred to as the Beer- Lambert law or the Bouguer- Beer Law. The principle is based on an electromagnetic radiation that is passed through a sample‚ wavelength is detected by the sample. As a result strength of transmitted light is gradually reduced. The measurement of the reduced strength of radiation is supported by the spectrophotometer. Based on Beer’s Law the strength

This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating

The 1980s: A time of the Yuppies‚ Brat Packs‚ and Rock and Roll In the great words of Ferris Bueller‚ “Life moves pretty fast. You don’t stop and look around once in awhile‚ you could miss it” ; the infamous 80s went by fast‚ but with the invention of the internet in the 80s‚ we can reminisce and unveil the distinct fashion‚ arts and music of the decade. Fashion from the 1960s/70s evolved into the 1980s. America’s wealth prospered‚ a decade consisting of traditionalism‚ luxury‚ and consumerism

October 1‚ 2013 Chemical Reactions of Copper Objective The objective of this lab is to convert copper (Cu0) “in a series of reactions to various compound containing copper as the Cu2+ species” (CHM111 Laboratory Manual) in order to prove the Law of the Conservation of Mass. Introduction In this experiment‚ we took a look at how copper (Cu0) reacts with different substances to get an end result where it is transformed back to its original state. There were five different reactions that involved

THE S-CURVE Introduction The first time most project managers become aware of the existence of S Curves is when they are requested by the client or senior management to include one in their next progress report. The following explains what the mysterious S Curve is‚ why it is an important project management tool‚ and how to generate one. What is a S Curve? A S Curve is defined as "a display of cumulative costs‚ labour hours or other quantities plotted against time. The name derives from
