Lab: Comparison of Three Isomers of Butanol Pre-lab: 1. Write the general reaction of an alcohol and HCl. 2. What would the solubility be of an alcohol in water. 3. What would the solubility be of an alkyl halide in water? 4. What is the purpose of KMnO4 in the reactions? Safety: Concentrated hydrochloric acid is corrosive and the vapour is very irritating to the respiratory system. Avoid contact with skin‚ eyes‚ clothing‚ and the lab bench. Wear eye protection and a lab apron.

Chromatography serves mainly as a tool for the examination and separation of mixtures of chemical substances. Chromatography is using a flow of solvent or gas to cause the components of a mixture to migrate differently from a narrow starting point in a specific medium‚ in the case of this experiment‚ filter paper. It is used for the purification and isolation of various substances. There are two phases in chromatography: 1. Stationary Phase – a solid that does not move. In this experiment was the

My Thought’s on the separation of Religion and Government. I believe these United States‚ to be a country founded on religious beliefs. At the end of the Constitution‚ before the founding fathers signatures‚ it says “Done in Convention by the Unanimous Consent of the States present the Seventeenth Day of September in the Year of our Lord one thousand seven hundred and Eighty seven and of the Independence of the United States of America the Twelfth. In Witness whereof We have hereunto subscribed

The First Amendment to the United States Constitution enjoins the government from interfering with any religion or church‚ but does not legislate against a religion or church interfering with the government. The first amendment to the constitution states that “…no religious test shall ever be required as a qualification to any office or public trust under the United States.” One of the reasons people migrated to the New World in the first place was for religious freedom‚ and when our constitution

hardened cement itself‚ the r eason of not using neat cement past on these test is in th e following two points: 1. Difficulties in molding (Getting good specimens). 2. Large variability of test results. It is important that the resul tant mixture (Cement + sand + water) has the same properties as concrete. So the standard sand was chosen and the following properties were determined to it: 1. Consist of pure siliceous material. 2. The particles are nearly spherical shaped. 3. The size

workers. The division or separation of works has both positive and negative effects on the construction industry. The quality of work is maximized by applying specialized workers to specific jobs and job completion time can be decreased significantly. The work completed by specialized workers has a lower rate of failure and reprocessing. The level of supervision required for specialized workers is quite low as compared to general workers. One of the negative effects of work separation on construction industry

Experiment #4A- A Separation and purification Scheme Amena Alkeswani‚ PHCC Dhanlal Murally‚ PHCC September 27‚ 2012 Abstract: There are millions of different organic compounds. Most of them are found in mixtures and in order to achieve a pure form they need to be separated‚ isolated‚ and purified. However‚ there are endless numbers of possible mixtures‚ which make it impossible to have a pre-designed procedure for every mixture. So chemists often have to make their own procedures. The purpose

Hanna Mae Laluces‚ Ina Bianca Lanuza Department of Chemistry‚ College of Science *Corresponding author; e-mail: knight_BeNcH66@yahoo.com Abstract Chromatography is a powerful technique for separating and/or identifying the components in a mixture. There are different types of chromatography and each has its own strengths and weaknesses. In this experiment‚ pigments of the chili pepper were extracted with the use of hexane‚ hexane-DCM‚ DCM‚ and DCM with methanol; then‚ the extract was introduced

The proof of the complete separation between the monster-entity and the human-entity is indicated by the fact that Jasper does not remember killing Edwin but the monster does. By creating the monster and attributing him Jasper’s vices Dickens plays with erroneous beliefs of the time

New World either ended up in the North or the South. As the people began to thrive there; differences‚ especially in the economy‚ began to become more prominent between two. They type of land the English landed on was the driving factor in the separations of the economy between the North and the South. The climate in the North was very different from the climate in the South. In the North you had four distinct seasons‚ which limited farming abilities. Which meant that you couldn’t base the economy
