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

Boyle’s Law Experiment Aim To show that Pressure is proportional to the inverse to volume Method A gas syringe was attached to a pressure sensor. The pressure sensor was calibrated‚ assuming the atmospheric pressure at the time of the experiment was 100kPa. Differing volumes of gas were created in the gas syringe and they were recorded as were the corresponding values of pressure at that particular volume. The volume was varied between 20cm3 and 75cm3. Results A set of readings was obtained

researchers will be conducting the studies with respect to the subject’s natural rights as a human being. History shows us that medical studies have not always been conducted this way. The Jewish Chronic Disease Hospital‚ The Tuskegee Syphilis experiments‚ and the Hepatitis studies at the Willowbrook State School‚ are a few examples of highly unethical research studies that have previously been conducted. Willowbrook State School may be one of the hardest to consider ethically‚ because it involved

In the first experiment‚ the bacteria R. fascians and R. corynebacterioides grew equally well in all conditions of light‚ except ultraviolet light. We tested this by comparing the petri dishes to the petri dishes that grew without light. Here‚ the exposure time was constant for all the lights and no light‚ which is 48 hours. The light sources were different. However‚ none of the lights had an effect on the bacteria‚ for the bacteria just continued to grow normally. The only exception was that UV

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

the potential energy is constant along the chain and sharply rises to infinity at the ends. Therefore‚ we can replace the electron system by free electrons moving in a one dimensional box of length . Objective: The purpose of this experiment is to obtain the visible spectra of several cyanine dyes and then interpret them to a simple model of the electronic structure of the π system: the Particle in a Box. Theoretical Model “Particle in a Box” In the Particle in a Box model

EXPERIMENT 5 TRANSVERSE STANDING WAVES A string attached to a turning fork is set vibrating at the same frequency as the tuning fork. The length and tension in the string are adjusted until standing waves are observed on the string. By knowing the tension in the string and the wavelength of the standing waves‚ the frequency of oscillation of the string and thus‚ the tuning fork is found. This value is then compared to a strobelight determination of the frequency. THEORY
