Introduction The production of acetone and butanol by means of solvent-producing strains of Clostridium spp. was one of the first large-scale industrial fermentation processes to be developed‚and during the first part of this century it ranked second in importance only to ethanol fermentation. The reason for the almost total demise of this fermentation in the early 1960s was the inability of the fermentation process to compete economically with the chemical synthesis of solvents. However‚ interest

The Increasing Enthalpy of Combustion Rates for Pentanol Isomers EEI Report Draft - JEREMY SAJU 11B Fuels are the main energy source of the modern world. The topic of this extended experimental investigation is to explore combustion rates of alcohols‚ specifically pentanol and it’s relationship with varying structural isomers. A fuel is defined as a material that stores potential energy that‚ when released‚ can be used as heat energy (Chemguide‚ 2003). The balanced combustion equation for pentanol

CheckPoint: Comparison of Three Sculptures Brianna Setzer Art/101 June 20‚ 2014 Kristy Yau CheckPoint: Comparison of Three Sculptures Learning that there were actually different versions of David came as a surprise to me. I am not a fan of art and never expected to be interested in learning about sculpture. The three artists featured in this checkpoint all have a different styles for this same sculpture. I will cover each in an order that seems more logical because in a sense‚ I believe that

bring new of his brothers. While at the front of battle he heard the giant Goliath’s defiance instill fear in the men of Israel. David unexpectedly offered to fight Goliath and actually killed him using only his sling shot and a pouch full of stones. Three artists depicted this biblical story in the Renaissance and those artists were Michael Angelo‚ Donatello‚ and Bernini. Donatello’s depiction of David best illustrates the story of David. Michael Angelo’s David was reminiscent of Greek classical sculpture

People from all different backgrounds and people who are fighting for different causes feel comfortable enough gathering here to have their beliefs heard. Recently‚ three suffragists – Miss Jeannie Rodgers‚ Mrs. Maud Preston‚ and Miss Alice Hallam – presented some of their ideas as well as some goals of the suffrage faction at Polly’s. While I may not agree with the suffragists on some of their beliefs‚ it cannot be

use of tert-butanol was needed to perform phase changes. Tert-butanol is colorless oily with sharp odors‚ mixes with water‚ and has a freezing point of 78 degrees Farenheit (PubChem‚ 2016). This substance allows for proper testing due to its freezing point being at room temperature. Tert-butanol can easily show how the process of phase changes can happen without having to take the time to freeze a different substance. It is also necessary to note the molecular formula. Tert-butanol is C4H10O‚ which

The U.S. Supreme Court is seen as the one of the highest courts‚ due to it having its own original jurisdiction in limited categories. This Court is extremely importation and it plays a huge role in society. The Supreme Court is able to have authority over any federal or state case and helps to find out whether the case is violating

Discussion: For this experiment our primary goal was to observe and note the reaction of butanols with hydrobromic acid. Before the lab began we discussed and proposed mechanisms. (see “Mechanisms”) To begin this experiment we calculated how much of each material we were going to be using‚ and the numbers we chose to use differed from our reference text slightly. We used 6.5 mL of our assigned butanol and only 4 mL of sulfuric acid. Going back to our reaction mechanisms‚ we were looking at SN1
