The Absorption Spectrum of Cobalt(II) Chloride Thang Dinh Lab partner: Alex Yang CHM 151 – 102 11/17/2014 Introduction: Many compounds absorb a certain spectrum of visible light. Since Beer’s Law describe the relationship between molar absorptivity and concentration‚ one could use his equation A = kc to find the unknown concentration by the known absorptivity. The graph of absorption spectrum is represented by a linear regression. From the graph‚ one could deduct that as the concentration decreases

What is the definition of autism spectrum disorder? Autism spectrum disorder is a general term for the complex neurological diseases that affect brain development. The common characteristics of the disease are difficulties in social interactions‚ speech communication and repetitive sounds and movements. In May of 2013‚ the DSM-5 diagnostic manual placed all autism disorders under one umbrella known as ASD or autism spectrum disorders. This merged all of the sub-types like Asperger syndrome‚ autistic

BIOSC 0050 Oct. 9‚ 2012 Dead or Alive? (Week 2) Post-Lab Assignment Results: The results of the Feulgen’s Schiff’s Stain test are that samples ALV-188-23 and ALV-843-20 turned magenta and samples ALV-882-21 and ALV-694-02 did not turn magenta. The result of the tetrazolium test is that all four of the samples did not turn pink. We were not able to conduct the detailed analysis of cultured plates with growth‚ so not results are available for this test. Discussion: For the Feulgen’s/Schiff’s

RESULTS AND DISCUSSION In the Iron (II) - Silver Ions System the reaction had a balance chemical equation of Fe2+ + Ag+ Fe3+ + Ag(S). The process if centrifugation is used in this part of the experiment to be able to separate the supernatant and the precipitate. And the supernatant will be used to test for the presence of Fe2+‚ Ag+ and Fe3+ in the solution. Results showed that there is a positive presence for FE 2+‚ Fe3+ and Ag+ because of the visible change of color of Prussian blue precipitate

The results for nitrate were inconclusive‚ there are traces of nitrate in wells 15‚ 20‚ 23‚ and 21 but we couldn’t find the source. We believe that number 15 is the source but there is very little amount of pollutants in the water to make the solution turn black. Wells 15‚ 20‚ 23‚ and 21 when tested for nitrates‚ the iodine changed to a yellowish blackish color. The hypothesis was not supported‚ well number 26 did not test positive for any of the pollutants. The first well tested was well number
