chemically active extraction then to identify the unknowns by analyzing the physical properties on IR and NMR spectrums. The neutral solid was purified through recrystallization and the melting point range was determined to be 47.5oC to 48.9oC. The basic liquid was purified with simple distillation and the boiling point of 135oC was concluded. Through the analysis of IR spectrum of each unknown the structures for each unknowns were devised. An important peak for the solid unknown D was 1655.71 cm-1 (Ketone)

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

Dylan McFarland 9/15/14 Honors Chemistry Richardson Lab: Measuring the Density of Pennies Pre-Lab Questions: 1. The equation that relates density‚ mass‚ and volume is: density = mass / volume. 2. All substances have unique densities‚ so if you are able to find the density of a substance‚ you can properly identify it. 3. We measure irregular-shaped objects with the use of water displacement because it would be nearly impossible to get the exact measurements

The Cheating Culture 5 Key Points In the 1990’s‚ the Sears Auto Repair chain instituted a production quota for it’s auto repair staff‚ so the mechanics started billing their customers for maintenance on their cars for unnecessary and costly maintenance.

A force can do one of four things to an object: 1. Make it speed up - accelerate. 2. Make it slow down - decelerate. 3. Change its direction. 4. Change its shape. If something is doing one of these four things there must be net force acting upon it. Newton’s First Law ’Every body continues in a state of rest or uniform motion unless acted upon by an external force.’ Something without net force acting on it will either stay still or move at a constant speed in a straight line until
