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

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.

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

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.
