Favourable Reaction Conditions One can use Le Châtelier's principle to explain the most favourable reaction conditions for the production of nitrogen (II) oxide. By decreasing the pressure, temperature or by adding/removing different components of the reaction, one could manipulate the equilibrium creating the most favourable reaction conditions. By decreasing the pressure the equilibrium will shift by producing more molecules in order to increase the pressure of the reaction again. The equilibrium will move in such a way that the pressure increases again. Due to the fact that the ratio of the molecules is 9:10 in the reaction, by decreasing the pressure the position of equilibrium will move towards the right-hand side of the reaction.
At this point, the sponge contains residual magnesium and magnesium chloride. Thus, the sponge is crushed and treated with hydrochloric acid and water in order to eliminate excess magnesium and magnesium chloride. Another method for removing the residues is the high temperature vacuum distillation. Although the hunter process is similar to the Kroll process, the hunter process is more expensive and it is only used for the production of small amounts of high purity powder. The hunter process follows the same steps as the Kroll process except for the fact that sodium is added to the vessel and therefore, NaCl is the salt that is entrapped in the pores of the sponge formed.
Toluene and cyclohexane have a boiling point difference of 30 degrees Celsius. The norm for performing a fractional distillation over simple distillation is if the boiling point values are within 25 degrees Celsius from each other. In theory a fractional distillation will give more accurate results since they are relatively near each other. The actual reaction was fairly straight forward with the distillation of the mixture solution followed by a gas chromatography of the 16th and 31st mL for analysis allowing us to find the amount of cyclohexane versus toluene in those samples. The success of this experiment was dependent largely on how well the apparatus was setup to ensure proper distillation of the solution.
2.1 Gas Compressors Usually, the gas pressure is maintained at 1000 to 1500 psig, when gas is transported through pipelines, while the gas pressure increases up to 3000 to 5000 psig, if it is transported as CNG. When high pressure is required and gas flows at relatively higher rates, reciprocating compressors are the best choice to compress natural gas. Reciprocating compressors are also used to compress air. 2.1.1 Reciprocating Compressors The reciprocating gas compressors physically reduce the volume of gas present in a cylinder with the help of a piston. When the gas volume decreases, the pressure increases accordingly.
Hydrogen Peroxide at high concentrations can be lethal. Catalase is there to help with the processes of breaking it down to assure that this doesn’t happen. The purpose of this lab was to help us understand what happens when an enzyme works with a substrate to make the reaction faster. It was to help show us what the effects of pH and temperature on the enzyme’s reaction. My hypothesis for the experiment was that the optimum temperature for catalase to function is 98.6o F because this is the optimum temperature for the human body.
Diesel fuel has a higher density which makes the motor have better fuel economy. Compared to a gas motor, the diesel motors fuel economy will increase about 20 to 30%. A gas burning truck will get at best around 15 mpg versus the diesels 18 to 20mpg. Over all the diesel motor is the way to go for
Carbon dioxide is in its supercritical fluid state when both the temperature and pressure equal or exceed the critical point of 31°C and 73 atm. In its supercritical state, CO2 provides the ideal conditions for extracting compounds with a high degree of recovery in a short period of time. Near liquid densities increase the probability of interactions between the carbon dioxide and the substrate, similar to a liquid solvent. The gas-like diffusivities of supercritical fluids are typically one to two orders of magnitude greater than liquids, allowing for exceptional mass transfer properties. Moreover, near zero surface tension as well as low viscosities similar to gases, allow supercritical fluids to easily penetrate a microporous matrix material to extract desired compounds.
the second cause of global climate change is fluorocarbons. Fluorocarbons are man-made chemicals used in refrigerants, solvents, and anesthetics. These chemicals contribute to the greenhouse effect, warming the Earth. The amount of these gases in the atmosphere and their atmospheric concentration is lower than carbon dioxide but, they are a lot more potent. Even though the use of fluorocarbons has been phased out, they still exist inside of older equipment.
Last month the average gas price was $3.54 per gallon, today gas is averaging at $3.04. Prices have been lower these past couple weeks, but prices are still high especially with how bad our economy is right now. A great way to save money and to help our economy is to go green. One way to do that is to drive hybrid vehicles instead of fossil fueled vehicles. Not only will you be saving money on fuel but you will also be helping our planet.
Why or Why Not? Most definitely! No matter the price of the fuel, the fact that it will save the environment from harmful pollutants and gases is worth every penny in my book. * How many gallons of gas would you save annually if you bought one of these vehicles? If I were to buy one of these vehicles, I think it would be either the electric car or the natural gas powered car, but most likely the electric car.
