The purpose of this lab was to use gas chromatography to determine the relative amounts of the three components of gas products from the dehydration reaction of 1- and 2-Butanol with sulfuric acid and the dehydrobromination reaction of 1- and 2-Bromobutane with potassium tert-butoxide. E1 reactions are two-step unimolecular reactions. The first step of an E1 reaction occurs when a leaving group‚ which consists of a weak base‚ leaves an organic compound‚ leaving an intermediate carbocation. In the

The Layers of Research Design Introduction: The purpose of doing research is mostly to answer a question or to solve a problem. The research work is started by identifying what type of data is needed and sources of obtaining this data. There are a number of data collection techniques such as questionnaires‚ interviews and personal observation. Besides all these sources secondary data can also be used. The final decision about overall research design is represented by selection of technique(s) used

Experiment 112-5 Thin Film Interference Introduction When two waves of equal intensity combine‚ the intensity of the resulting wave can be anywhere between zero and four times the intensity of the individual waves‚ depending upon the phase difference between them. When they are in phase (the maxima coincide with maxima and the minima coincide with minima)‚ maximum intensity results. When they are exactly out of phase (the maxima of one wave coincide with the minima of the other wave)‚ the

Layers of the Grand Canyon During the earliest periods of the Grand Canyon formation where we have Tapeats sand stone‚ bright angel shale and muav limestone it would appear that there was a relatively shallow‚ warm sea. This is indicated by the presence of Trilobite fossils found in this layer which thrived in that environment. Trilobites were early animals that had exoskeletons that are usually the only part of them that is preserved in the fossil record. They were marine bottom feeders who thrived

Ozone layer damage is one of them. The objective of this paper is to review the origin‚ causes‚ mechanisms and bio effects of ozone layer depletion as well as the protective measures of this vanishing layer.

three main layers also known as the Epidermis‚ Dermis‚ and the Hypodermis. The Epidermis is the outermost layer that shields the body and consists of four cells types and five distinct layers. The Dermis is right under the Epidermis which contains strong connective tissue. This layer also contains our hair follicles that help regulate our body temperatures‚ nerve endings which let’s us sense‚ and sweat glands which help the skin keep moist. Lastly‚ the Hypodermis also known as the “Fat layer”‚ it isn’t
