Aim: This is the reason for doing the experiment. It may contain a research question‚ but it must state what it is that we are investigating or what we hope to find out. Hypothesis: This is the basis behind your plan which leads you to believe that the experiment can be successfully carried out. It may also contain a prediction of the final answer (supported by a reason) Method: This is what was actually done or is going to be done. It may need a diagram‚ in which case it should be drawn

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

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

test subject. Every test subject that underwent the exercise‚ had an increase in both blood pressure and heart rate. Some of the test subjects were more athletic and didn’t have as big of a difference as some of the more unathletic subjects. In conclusion‚ a person’s heart rate will increase some amount after going through rigorous physical

Imagine if you became a volunteer in a research study? Where you don’t have rights to ask questions of procedures being done to you or maybe choose without the option to refuse. One of the worst medical experiences in history was the Tuskegee experiment. In Macon County‚ Alabama the Public Health Services along with the Tuskegee Institute started a study in 1932 and continued for about 40 years. It was a research study that involved 600 men which 399 had syphilis and 201 didn’t. The purpose for this

LTSpice‚ there were differences on the peak-to-peak voltages. As the voltage peak to peak is increased‚ the clipped voltages were also in a higher position in the graph. The simulation and oscilloscope readings matched the expected result. Conclusion In conclusion‚ diodes are of important use with different electronic circuits. There are also different types of circuits where diodes are used. Diodes are useful in different electronic circuits. A type of circuit where at least two diodes are involved

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

Silver Mirror Experiment Background: This experiment was first conducted by Bernhard Tollens‚ it is used to determine whether a carbonyl containing compound is an aldehyde or a ketone. An aldehyde is a compound containing a formyl group (CHO).The experiment involves diamminesilver complex and a chemical reagent (also known as “Tollens’ reagent”) which in this case is glucose. In a successful experiment a reflective silver metal should precipitate‚ with characteristics identical to that of a mirror’
