In conclusion to the distillation lab‚ I think our data shows that our experiment went well. Our graph resembles the graph in the lab handout (graphs attached to lab notebook sheets). The fractional distillation shows the sharp slope between when the cyclohexane burns off and mostly only toluene remains. The microscale graph seems to be accurate because it shows the large jump where the cyclohexane is burned off. To view the apparatuses used in the experiment look at the attached pictures. To

Conclusion: As we have learned from all the information presented to us in the communication world‚ there are many choices out there to relay tidbits of talk‚ video‚ emails‚ text‚ global connection via MySpace or Facebook‚ and face to face communication via webcam; it all just depends on how you (as a user) chooses to use the outlet. All the communication we have investigated has to do with mostly snippets of information‚ like a text through Twitter‚ or a blurp on Facebook; these are not communication

Barry Allahyar Dr. Dodd CHEM 2122 2010-09-16 Experiment 19: Fischer Esterification‚ Conclusion The objective in this experiment was to efficiently perform an Fischer esterification of 1-butanol and acetic acid to form water and n-butyl acetate‚ and to confirm the esterification using IR spectroscopy analysis. It was found that 0.734 grams of n-butyl acetate was formed with a percent yield of 61%. The product was confirmed using IR spectroscopy and boiling point confirmation. The reaction mechanism

Conclusion Teen pregnancy is a pregnancy in female human-beings who are below the age of twenty years and being a teen parent it isn’t as great as it sounds. Teen pregnancy should be highly discouraged has it has effect on the teenage mother and the baby born. The teen mother may face complications such as premature labor‚ medical complication during the pregnancy period‚ at child birth or after child birth and are likely to drop out of school. One cause for an early pregnancy for a teenager

Lab Conclusion on Density In the lab of measuring density‚ precision and accuracy are very key components. Precision is the exactness of a measurement or good technique. Now accuracy is the value that we measured compared to the true value that the book has. Precision and accuracy are important because you need to have good technique and have your value close to the true value to minimize the error analysis. If you do these steps correctly you are a good chemist but if you do them poorly they

Caitlin 11/25/12 Freedom of Speech Silence What is democracy? Democracy is a form of government where the people rule‚ not a dictator‚ a king or aristocrats. Democracy means that people have a say in law and state. This is impossible to do without a voice. How are people supposed to run the government if they aren’t allowed to speak their mind? This is hypocrisy. That is like telling someone they can travel where ever

of territory. As Dahrendorf states; "We want to find out what it is in German society that may account for Germany ’s persistent failure to give a home to democracy in its liberal sense". But can we really analyze the problem in this way? It has not always been the same "persistent failure" hindering Germany from giving a home for democracy‚ but rather the problems faced by Germany throughout history. To truly understand the German situation and its multiple struggles for unification‚ it is important

Alum Lab Conclusion The purpose of this laboratory was to use two different techniques to attempt to identify the melting point and the mole ratio of hydrated water to anhydrous aluminum‚ potassium‚ and sulfate of AlKSO4. The hypotheses were: if the alum was put in a capillary tube the melting point of alum will be able to be determined; and the water of hydration in alum crystals will be possible to determine if the alum is heated with a Bunsen burner.

VI- CONCLUSION The eye is the organ of vision. It has a complex structure consisting of a transparent lens that focuses light on the retina. The retina is covered with two basic types of light-sensitive cells-rods and cones. The cone cells are sensitive to color and are located in the part of the retina called the fovea‚ where the light is focused by the lens. The rod cells are not sensitive to color‚ but have greater sensitivity to light than the cone cells. These cells are located around the
