To set the ammonia fountain experiment up I made sure I had all the materials the lab required me to have which was: a Florence Flask, a 600 mL beaker, a Mohr pipet, distilled and tap water, a polyethylene wash bottle, a phenolphthalein indicator, concentrated ammonium hydroxide, sand, a heating mantle, a ring stand, clamps,…

Introduction The purpose of this lab is to create two material samples through the process of powder metallurgy. After these samples have been manufactured completely through this process then they are evaluated under a microscope. One sample was sintered, and the other one was in its original compacted state for a comparison of how sintering…

The study of the nature of light is an important research area in modern physics. Many, including the theoretical physicist Albert Einstein, have contributed to theories involving light. Of these, the wave-particle duality is arguably the most strange and noteworthy concept in the field. Throughout history, some physicists have argued that light behaves as a…

Photovoltaic cells are solid state devices that convert light directly into electricity. Photovoltaic literally means “light electricity.” These devices can be commonly found providing power for small scale devices such as calculators, watches, and small radios. However, they are not limited to small scale systems. They are also used to power satellites, communications equipment, houses…

Objective: Separate and purify acetanilide from a mixture by recrystallization. Compare the melting points of crude and recrystallized acetanilide. Introduction : The most common method of purifying solid organic compounds is by recrystallization. In this technique, an impure solid compound is dissolved in a solvent and then allowed to slowly crystallize out as the solution…

This Laboratory survey trades with the Analytic Procedure of the Measurement of Partition Coefficient. Partition Coefficient is a really of import standard for Organic substances. It finds usage in Pharmaceutical Industry, Pollution suspension systems, Agro Chemicals, and Chemical Industry. There are many methods available for finding the Partition Coefficient, particularly Instrument methods like, Chromatography, Electrophoresis…

 Describe what is necessary for a substance to be a conductor Of electricity. In order for a substance to be a good conductor of electricity, there must be charged particles in the substance, ions or electrons. These particles must be free to move within the substance. Form a hypothesis as to whether distilled water is…

During the first decade of the twentieth century the world-wide demand for ammonia for use in fertilisers (in the form of nitrates) and in the production of explosives for use in mining and warfare could only be satisfied on a large scale from deposits of guano in Chile (2). Though this deposit was of huge…

An SN1 reaction of tert-butyl chloride takes topographic point in two stairss. First. the Alkyl Halide will go forth the molecule. In this measure the bond is interrupting. which takes a longer sum of clip. so it will find the rate of the reaction. As a consequence. it forms a third carbocation. since this is…

Abstract In the experiment performed, the aim is to polymerize Styrene. This is achieved using emulsion polymerisation with the use of persulfate as an initiator. The experiment resulted in a 73.8% yield. Introduction Polymers are synthesized by solution or emulsion polymerization methods. Emulsion polymerization is the most common process used to manufacture polystyrene. Emulsion polymerization…
