    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 (23.5 C) and the temperature

    Beer’s Law Lab Report Abstract: The Beer’s law lab was conducted to determine the optimal wavelength of Co(NO3)2·6H2O with the use of spectrometry. The results determined that the optimal wavelength to study the absorbance of this salt was 500nm. It also demonstrated how transmittance of light and absorbance of light are inversely proportional because absorbance is calculated by multiplying transmittance by a negative log. Introduction: When one is studying chemicals‚ there are many important
