Juliana Park Mayumi Tamada CHEM 111B LAB/ M-F 1-4PM 15 August 2012 Spectroscopy Lab Introduction In this lab, the molar absorptivity of the complex FeLn2+ will be determined by using the absorbance of the complex and its concentration. The absorbance will be found by using a spectrophotometer. For the next part of the lab, the formula of the complex will be determined by also using the volume of ligand and the absorbance again. Experimental There are two different parts to the experiement. In the first part, five 100 mL flasks of 5 mL ligand solution, 5 mL 2 M sodium acetate, 4 mL 3 M NH2OH, and 1-5 mL Fe2+ solution are diluted with water.
Introduction: Thyme contains a surprising amount of iron compounds. This experiment enables us to determine the amount of iron(II) present in dried thyme by means of a redox reaction. Method: 1. Weigh accurately about 1g of dried thyme and put into a 250cm3 beaker. Record the mass of thyme used.

The process of changing one element into another is called transmutation. The two main ways that a transuranic nucleus can be produced is by bombarding its nucleus with ions or neutrons. These ions or neutrons can be captured by the target nucleus and produce heavier nucleus. Transuranic element 1: U-238 is bombarded with neutrons it can be converted to U-239 which then undergoes beta decay to produce neptunium and plutonium. Pu-239 is changed to americium-241 by neutron
