Organic Chemistry I Simple and Fractional Distillation The Simple and Fractional distillation experiment was divided into two parts. We split up the procedure in this experiment. My group did the simple distillation and we received the Fractional distillation from another group in class. In this experiment‚ we examined the effectiveness of fractional and simple distillation to determine which is more successful at extracting a pure sample. This experiment was very successful. We are able to

Investigation on the effects of Temperature‚ pH levels‚ and Enzyme Concentration on the reaction rate of the Decomposition of Hydrogen Peroxide by Catalase The purpose of this investigation is to figure out how temperature‚ pH‚ and enzyme concentration affect the reaction rate of an enzyme. It’s important to understand how certain factors affect enzymes because of their crucial role in the metabolic processes of life. Enzymes lower the activation energy necessary for a chemical reaction to

textbook in 1789 on chemistry in it he introduced the Law of Conservation. He founded the 3 types of matter (solid‚ liquid‚ and gas). Along with this he also established the metric system. Lavoisier also made a lot of enemies because he had disproved various old theories. In experiment 2.1 we wanted to know if the mass of salt will

Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an

Lab Report Introduction This lab has the following two concepts: synthesis of acetylsalicylic acid and analysis of acetylsalicylic acid. Synthesis is a purposeful execution of chemical reactions to obtain a product. This concept is used in the first part of the lab; when we have to produce crystals of aspirin. Analysis is the separation‚ identification‚ and quantification of the chemical components of natural and artificial materials. This concept is used throughout the lab when we are analyzing

8. Terfenedine is an amino diol that is the active ingredient in the antihistamine Seldane. Mass spectral analysis of terfenedine shows a molecular ion at m/z = 471 and a peak at m/z = 472 which is 35.5% the height of the molecular ion. Terfenedine is known to contain C‚ H‚ O and N. (a) Suggest five molecular formulas for terfenedine. (b) Terfenedine has an even number of carbons and contains nine double bonds and four rings. Based on this additional information‚ what is the formula for terfenedine
