Jordan Toschak Kevin Hannon and Megan Blanford Physical Properties of Clusters of Galaxies Monday (4/15/2013) Procedure For this experiment‚ a photograph of the Virgo Cluster of Galaxies will be needed to observe. The photograph will be sectioned into specific areas with coordinates like a map. Locate the area and identify the galaxies. Classify the galaxies as elliptical‚ spiral‚ or irregular. An elliptical galaxy will appear solid with not real defined “arms” or spirals coming from the

Introduction The purpose of this lab was to explore the properties of an unknown compound. An unknown was given and a cation flame test and anion test was performed to determine the identity of the compound. Once the identity was determined‚ the properties were explored. Experimental To determine the cation of the compound‚ a cation flame test was performed. A bunsen burner was lit until a medium blue flame was burning. The given unknown was scooped onto a nichrome wire loop. The wire was held
