Flame Lab Objective: How an electron absorbs energy and re-emits it as light and why different elements have different spectra. Also to learn how to use flame tests to determine the identity of unknown mixtures. Hypothesis: We know that certain compounds will burn certain flame colors because they emit different wave lengths. Introduction: Neils Bohr made the “Bohr’s Model” in 1922‚ he found that electron travel in specified fields – which‚ when excited‚ will jump to different rings

Abstract The purpose of this lab was to test if ethanol affects the reaction involving hydrogen peroxide and catalase. Tests were performed by putting chicken liver‚ ethanol solution (diluted ethanol solution for other trials) and hydrogen peroxide in a test tube with a side arm‚ and having a rubber tube lead the oxygen gas into a gas collection tube. Results from the tests showed a negative correlation‚ this means that the more diluted the solution of 95% ethanol was‚ the less oxygen gas collected

of peroxidase activity. During the lab‚ the lab group tested 7 test tubes‚ including 1 blank‚ with different amounts of pH 5 buffer‚ H2O2‚ Peroxidase‚ and Guaiacol. After the certain amount of mL per substance was mixed‚ the absorbance readings for the effect of peroxidase concentration were taken from the spectrophotometer. The results for the effect

Williams‚ Brandon Physics‚ Period 1 23 May‚ 2014 Resonance Lab Purpose: To determine the speed of sound using the resonance method‚ temperature method and percent error. Hypothesis: If the temperature of the room’s 20 degrees C‚ then using the temperature method‚ the speed of sound is 344m/s. Vs – Vo + 0.6m/s T / C = 332 m/s + .6 m/s (20 C) / C = 344 m/s Conclusion: Using the resonance method the speed was 330 m/s. using the average temperature
