PREPARATION OF TIN TETRAIODIDE 09/06/2012 Introduction The objective of this project was to prepare tin tetraiodide through the following reaction: Sn+2I2∆SnI4 and to measure the melting point of tin tetraiodide. Tin tetraiodide was recrystallized after the synthesis. The percent yield and the theoretical yield of tin tetraiodide were calculated. Recrystallization is to further improve the purity of tin tetraiodide. The solvent is carefully chosen to be toluene in order to maximize the recovery

instrument like mine would be the flute because it has two open ends like mine does. The physics behind a flute is that it can either be an open or closed end pipe and it depends on what kind of flute you get. With the harmonics the lower holes are in the flute to shorten the air column to raise the fundamental frequency of the open air column. To make an higher note you can force the air column to sound its second harmonic‚ up an octave from the fundamental.In a flute decreasing the slit-to-edge distance
