  • Calorimetric Determination Of Enthalpy Of Sodium Sulfate

    The Calorimetric Determination of Enthalpy and Entropy Changes of the Thermal Decomposition of Sodium Sulphate Decahydrate Abstract Sodium sulphate decahydrate thermally decomposes to anhydrous sodium sulphate at 50⁰ C and cools to form anhydrous sodium sulphate. Using Hess's Law the enthalpy and entropy changes of this process can be determined in order to deduce the spontaneity of the reaction. The transition temperature was determined by melting the hydrated crystals at 50⁰ C and allowing…

  • Copper Created Lab Report

    Was More Copper Created? Harshal Patel* and Isaac Cenoz Chem 111-491 Introduction: Copper is one of the most important and diverse elements found in nature all over the world because it can be chemically reacted with many other elements and compounds. The purpose of this experiment was to identify the different reactions that occurred through the lab and the different types of reactions. Throughout the lab, copper was put through series of reactions to see the different combinations and how its…

  • Catalase Reaction Rate Lab Report

    Reaction Rate Introduction Catalase is a vital component in the human body. The most crucial of which would be Enzymes, these are protein catalysts. A catalyst speeds up a chemical reaction rate. Virtually all chemical reactions within the human body require a catalase enzyme to be completed in the proper amount of time. The decomposition of hydrogen peroxide to oxygen and water can be completed with the catalase enzyme (Thompson, 2005). In the experiment completed, this is shown through the…

  • Film: A Synthesis Essay

    One process to meet these criteria is chemical bath deposition .The chemical bath deposition technique involves the controlled precipitation from solution of a compound on a suitable substrate. The technique offers many advantages over the more established vapour phase synthetic routes to semiconductor materials, such as chemical vapour deposition (CVD), molecular beam epitaxy (MBE) and spray pyrolysis. Factors such as control of film…

  • Case Study Of Carbon Nanotubes

    CHAPTER – 1 1. INTRODUCTION Carbon nanotubes are allotropes of carbon with cylindrical nanostructure. Constructed with length-to - diameter ratio of up to 132,000,000 :1. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. Nanotubes are members of fullerene structural family. Nanotube’s walls are formed by one-atom thick sheet of carbon called Graphene. The combination of…

  • Adipic Acid Case Study

    sources. Fire involving large amounts of material should not be approached individual containers may rupture abruptly causing ‘fireball’ effect. Fire-fighters should wear self-contained breathing apparatus and full protective clothing when fighting chemical fires. Use water spray to cool nearby containers and structures exposed to fire. 5. Accident Release Measures In case of spill, do not blow material. Sweep or gather up material and place in proper container for disposal.…

  • Oligoetherol Synthesis

    New method of synthesis of oligoetherols with carbazole ring Renata Lubczak Abstract: The new method of synthesis of multifuntional oligoetherols with carbazole ring suitable for obtaining the polyurethane foams of enhanced thermal resistance was presented. At the first step of the synthesis the carbazole was reacted with excess glycidol to obtain the product of (n +1) functionality, where n is number of equivalents of glycidol reacted with carbazole. Carbazole reacts with glycidol without…
