Purpose: The purpose of this experiment is to apply Beer’s Law by analyzing samples provided by Q laboratory to determine their absorbance and prepare a Beer’s law plot. Molarity of these samples was also calculated to determine concentration and percent error rate. Students also analyzed the concentration of blue dye #1 to determine the concentration of blue dye #1 in a commercial blue dye drink. Procedure: To drop solutions into the test tubes and then determine the Beer’s Law relationship of

of reacting increases; resulting in a greater amount of NaCO3 reacted and greater generation of CO2. Percent by mass of NaCO3 that has reacted can be determined by using mass difference and dimensional analysis to relate the amount of CO2 produced to the amount NaCO3. Collective class data are exhibited in Table 1‚ and Figure 1 renders the class findings in a plot. As shown in Figure 1‚ the percent by mass of Sodium Bicarbonate in the Alka-Seltzer tablet primarily increased along with the volume

A Comparison of the Lincoln‚ Johnson‚ and Congressional Plans for Civil War Reconstruction After the Civil War‚ a great question arose. That question was what was to be done with the former Confederate States of Americas (CSA).

Chuck’s average tax rate is 19.83%. Average Tax Rate = [pic]=[pic] = 19.83% Chuck’s effective tax rate is 17.50 percent. Effective tax rate = [pic] = [pic] = 17.50% Chuck is currently in the 25 percent tax rate bracket. His marginal tax rate on increases in income up to $8‚600 and deductions from income up to $40‚500 is 25 percent. 35) [LO3] Using the facts in the previous problem‚ if Chuck earns an additional $40‚000 of taxable income‚ what is
