Synthesis of Tetraphenylcylopentadienone Post-Lab Report Purpose- This experiment illustrates the use of adol condensation for the synthesis of a five-membered carbocylic ring. It is also a good demonstration of the impact extended conjugation has on the absorption of visible light. The reactants are bright yellow in color while the products are a very deep purple color appearing almost black. Introduction- The synthesis of Tetraphanylcyclopentadienone was a further example of the adol

Joshua Berkebile 8-26-10 1st period Density Lab The purpose of this lab was to find the mass‚ the length‚ the width and the height of 4 different cubes so we could calculate the volume and density of them. We also had to find the density of irregular shapes by dropping them into a graduated cylinder than subtracting the starting water volume by the ending water volume. Density is how much mass is in a certain volume of matter. Volume is the amount of room that an object

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

Collecting Photosynthetic Rates in Spinach (Spinacia oleracea) Introduction: The purpose of this study was to see which light color would cause the spinach sample to photosynthesize the most within the given time. In order to understand photosynthesis‚ we need to know that chloroplasts absorb light energy from the sun‚ the plant then takes that energy along with water and carbon dioxide and changes it to sugar and oxygen. This happens in order for the plants to grow. But‚ light energy comes in a

Separation of the Components of a Mixture General Chemistry 1 (Chem 101)‚ ISP SCUHS Report 2 January 26‚ 2014 Abstract The analyses of mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques‚ we examined our solutions such as SiO2 (sand)‚ NH4Cl (ammonium chloride)‚ and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions‚ we made calculations

purpose of antimicrobial drugs is either to inhibit virus replication‚ without harming host tissues or to interrupt the cell processes or structures of bacteria‚ fungi‚ and protozoa. This lab has brought great interest to me because this is the way physicians’ control/treat infectious disease within our bodies. In this lab‚ chemotherapeutic agents were evaluated by the disk-diffusion method. Chemotherapeutic agents are placed on the surface of a Petri plate containing Mueller-Hinton agar‚ which allows
