In this experiment‚ we used simple distillation and extraction to do synthesis of 1-bromobutane. The experiment was carried out by mixing 13.3 g of sodium bromide‚ 15 mL of water and 10 mL of n-butyl alcohol in a 100 mL round bottom flask. We cooled the mixture and added 11.5 mL of concentrated sulfuric acid. Then the mixture was heated at reflux with a short condenser for 45 minutes and then we drained out the condenser. We removed the condenser and distillation head was set up to set up the condenser

Chapter 1 Exercise What is free software? List three characteristics of free software. Free software is code that is available for free to everyone‚ but it is also free in the sense that it can be used and altered freely to the user’s desires. It is free to be studied‚ redistributed‚ and modified. Why is Linux popular? Why is it popular in academia?Due to the operating system’s distribution among universities‚ students were able to become used to it’s sophisticated developing environment which

Unknown Lab Report Dr. Nathan Cahoone Microbiology 204 December 9‚ 2010 Introduction There are many reasons for knowing the identity of microorganisms. The study and test was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of an unknown bacterium which I was using unknown #25. Results Unknown #25 had the following morphology on a streak plate: medium sized butyrous cream colored colony. Gram-staining was utilized

Part 1 dilutions participated as a trail run to gather around the “full enzyme” that was used for the other parts of the experiment. Part 2 readings were in the time span of 10 minutes and the final results show a spontaneous increase in the first minutes of the absorbance readings. They then showed a steady reading towards the end of timing. The amount of enzyme is decreasing as the dilution occurred. The activity it catalyzes measures the amount of enzyme present in the reaction (Introduction to
