PurposeIn this experiment‚ sodium hypochlorite (NaOCl) in acetic acid mixture was used to oxidize emdo-borneol (an alcohol) to camphor (a ketone). The product would then be purified by sublimation and then be analyzed by Infrared spectroscopy and melting point test. Procedure and ObservationsPlease refer to the lab manual and the carbon copy attached. Data and CalculationsWeight of endo-borneol = 0.2013gNo of moles of endo-borneol = 0.2013g/154.25g mol-1 = 1. 305mmolSince one mole of endo-borneol

this goal by creating five reactions containing Sodium Sulfate that would confirm our compound and show its chemical properties. In each reaction‚ we replaced the presence of Sodium Sulfate with our unknown. Our first reaction was the reaction from the sulfate anion test between Sodium Sulfate and Barium Chloride. If the compound was in fact Sodium Sulfate it would produce a white precipitate and it did. The second reaction was first between Sodium Sulfate and Hydrochloric Acid‚ and then Silver Nitrate

Theory: A low-pass filter is an electronic filter that passes low-frequency signals and attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. It implemented using a resistor and a capacitor. The actual amount of attenuation for each frequency varies from filter to filter. A low-pass filter is the opposite of a high-pass filter. The below circuit diagram illustrates a simple ’RC’ low-pass filter. The range of frequencies passed by a low pass filter

Low-Cost Carrier A low-cost carrier or low-cost airline (also known as a no-frills‚ discount or budget carrier or airline or cheap flight) is an airline that generally has lower fares and fewer comforts. To make up for revenue lost in decreased ticket prices‚ the airline may charge for extras like food‚ priority boarding‚ seat allocating‚ and baggage etc. The term originated within the airline industry referring to airlines with a lower operating cost structure than their competitors. While the

airlines. The emergence and rapid growth of “low-cost” airlines is due in large part to their ability to deliver air transportation services at substantially lower costs and at higher levels of productivity than the traditional “legacy” airlines. In response‚ legacy airlines have had to find ways to reduce operating costs and improve the efficiency of how they utilize both their aircraft and employees. The selected reports make reference to the low-cost airlines or LCC. The first relates to the

Low Fat Diet vs. Low Carb Diet Low Fat Diet Fat is the number one enemy of a lot of people‚ particularly the medical people and people going into diet and are health conscious. It gets a lot of the attention for many good reasons. Cholesterol levels in the blood could increase because of it and ultimately a person’s risk for heart disease would also heighten. Also‚ some fatty foods‚ or basically the delicious foods such as bacon‚ sausage‚ and potato chips often have fewer vitamins and minerals

that were added from the burette is 0.00327 moles (1 tablet of Gaviscon). However‚ for Quick-eze‚ the number of moles is 0.00216 moles (1 tablet). This means the average volume of the NaOH have affected the number of moles as the concentration of the sodium hydroxide is 0.1M. This means that if less NaOH was required to neutralise the acid‚ the number of moles of HCl neutralized by the ant-acid would be greater. For example; by using mole ratio‚ the number of moles of HCl reacted with the NaOH is 0.00216

The purpose of this study was to observe the effect of different concentrations of sodium chloride have on the germination of lettuce seeds‚ Lactuca sativa. A study done by Katembe et al.‚ (1998) stated that an increase in salt solution in the environment of the seed will slow down water imbibition‚ therefore‚ preventing germination and
