Determining the unknown concentration of HCl via heat of neutralization of a reaction involving strong electrolytes and weak electrolytes. Myeongwon Lee 20522885 Partner: Frank Wong TA: Afsoon CHEM 120L – Earth Science & Chem 149 Section: 004 Tuesday‚ November 26th‚ 2013 Introduction All chemical changes are accompanied by change in energy and this energy is in form of heat. The energy change of a reaction that happens at constant pressure is defined as heat of reaction or enthalpy change and the

Stuart Mill‚ author of the chapter “Of the Liberty of Thought and Discussion” in the philosophical work On Liberty‚ outlines four main arguments of why society is impacted by the silencing of others’ opinions. Wayne Fuller‚ author of the chapter “Diffusion of Knowledge” in the work The American Mail: Englarger of the Common Life‚” presents ideas that Mill would be able to apply his ideas to. Mill’s first argument is that suppressed opinion has the possibility of being true‚ which is why no idea can

F1-F4: Emulsion Solvent Diffusion Method (ESD) The microparticles of formulations from F1-F4 which are prepared by ESD method were irregularly spherical in shape. The percentage yield increased with increase in polymer concentration from 88.3 to 93.6%. Stirring speed does not show any valid effect in the percentage of yield. Particle size increased with increase in the polymer concentration due to the viscosity character of the polymer which comes in contact with the drug to form microparticles

they depicted true thoughts of Jewish captives during this time period. Though most of the novel described life in concentration camps‚ three lines truly portray the feelings‚ emotions and mindset Jews had under the Nazi regime. "Never shall I forget those moments that murdered my God and my soul and turned my dreams to ashes..." (Wiesel 34). This line shows the impact concentration camps had on Wiesel’s life‚ soul‚ and belief. As a child‚ Wiesel became Godless for he saw no God of his would allow

War World 2‚ Concentration Camps During War World 2‚ Hitler authorized the SS‚ after December 1934‚ to be “the only agency authorized to establish and manage factories‚” called concentration camps‚ like Ravensbruck (ushmm.org). These camps were built throughout Germany and the system expanded as the Nazis took over. The system of the camps grew more deadly and affected many camps‚ like Ravensbruck. Ravensbruck was a camp mainly for women‚ and was deadly. In the end of the war‚ Ravensbruck was

The effect of environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH on microbial growth and survival Abstract: Microbial growth can be affected by different environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH. Six experiments were carried out in this report testing for microbial growth against different environmental factors. Good aseptic techniques were used to prevent contamination‚ resulting in a uniform set of results

Concentration Camps During the Holocaust Bergen-Belsen Concentration Camp was located in north central Germany near Hanover. The camp is named after the nearby villages of Bergen and Belsen. It was created in 1939 during World War II. In 1940‚ a prisoner of war camp was constructed. At the camp‚ the conditions were harsh and extreme; abuse‚ disease‚ and starvation was very common throughout. One woman‚ Alice Lok Cahana‚ who was deported from Auschwitz to Bergen-Belsen in 1944‚ described the camp

Abstract: The purpose of this experiment was to determine the concentration of an unknown amount of copper sulfate using the spectronic 20. Four solutions of different concentrations of H₂O and CuSO₄ were put into the spectronic 20 to observe their absorption of light. Then‚ a graph was created to plot down the measurements. Using the calibration curve of the graph‚ the concentration of the unknown substance was found out to be .12M. Background/Introduction: Beer’s law (which states that

We had started our experiment by learning about the change in the earth and what it does to the concentration in the oceans water. When global changes occur‚ they don’t only change that one thing it changes many things. Such as concentration in the water. For example‚ when heavy machinery or facilities burn fossil fuels‚ which releases more carbon dioxide in the air‚ the ocean sucks it up and the acidity in the water completely changes even if it goes up by .1 or .2 percent it’s still a lot and will
