    Organic Chemistry: CHP 225 Thomas Hsieh Experiment 2: Boiling Points o Date experiment was performed: September 16‚ 2011 o Objective: To determine the boiling point of organic compounds such as tert-butyl alcohol‚ sec-butyl alcohol‚ n-butyl alcohol‚ and an unknown. o Principle: Boiling point is the temperature at which gas and liquid phases coexist in equilibrium. At this temperature‚ the vaporization rate and the condensation rate are equal. The liquid and vapor reach a state of dynamic

    Crater Design Experiment Aim: To see how the height in which the ball is dropped from affects the depth of the crater. Hypothesis: I predict that as the height in which the ball is dropped from increases‚ so does the depth of the crater (the data will be directly proportional). The scientific knowledge which supports this is that the golf ball has a gravitational potential energy which increases as the ball is dropped from higher heights. When the height increases the ball gains more gravitational

    1. Dancing Raisins Here’s another quick and easy science experiment. All you need is a glass of clear soda‚ such as ginger ale or club soda‚ and several small raisins. Fill a glass with soda. Leave about ½ inch (12.5 mm) of space at the top. Drop the raisins in. Those tiny bubbles attaching themselves to the raisins are carbon dioxide (CO2) bubbles. The irregular surface of the raisins enables a lot of CO2 to accumulate. When enough gas bubbles attach to the raisins‚ they act like tiny balloons

    gradient with the help of energy input and specific transport proteins (Campbell and Reece‚ 2002). For the analysis of cell membrane permeability and the mechanism of controlling water‚ human red blood cell is a convenient specimen through hemolysis experiments ^^^^^. The human RBC osmotic content is about 0.9% NaCl. In hypotonic solutions‚ the cells swell because of water influx and eventually they hemolyze where cell contents including hemoglobin are released into the medium. This can be indicated by

    Bending Moment EXPERIMENT 2B: SHEAR FORCE AND BENDING MOMENT 1. ABSTRACT Performance-based design approach‚ demands a thorough understanding of axial forces. Bending characterizes the behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element. By this experiment we can verify the limit load for the beam of rectangular cross-section under pure bending. Moments at the specific points are calculated by the method of statics

    the electrons as a back donation to the pi orbital in DMSO. In the first experiment‚ I had to synthesized CuCl2~2DMSO to determine which DMSO atom; Sulfur or Oxygen‚ combined to Copper (II) Chloride. I was able to determine it base on finding the melting point and observing the Infrared Spectroscopy. Since copper is a hard metal‚ it will most likely bond to an oxygen atom because they are both hard. In the second experiment‚ I also synthesized RuCl2~4DMSO to determine which DMSO atom; Sulfur or Oxygen

    Risk Taking Experiment A. There are many risks in life one must take. I had several options to explore for this experiment such as going on a drop roller coaster‚ sky diving‚ and killing insects. I thought that sky diving would be fun‚ but I am not old enough to do because the minimum age requirement was eighteen years old. I also explored the idea of killing insects especially spiders which I hate the most‚ but I thought going on a drop roller coaster would be more interesting. B. I chose the
