HFOV and Gas Mixtures RES 262 Julia Fussell Sarah Bandy HFOV and Gas Mixtures The type of ventilation I will be discussing is High Frequency Oscillating ventilation. I chose this type of ventilation because of how different it is compared to traditional ventilation. “HFOV uses a constant distending pressure where an oscillatory flow along with clearly defined inspiratory and expiratory phases are generated in the lung”( adhb.govt.). Because the pressure is constant, it is easy to…

The melting point is the temperature at which a solid precipitate changes into its liquid form upon heating. It also helps when determine which isomers predominate. The experimental melting point of the E-stilbene was 242 degrees Celsius. The actual melting point of the E-stilbene was 241 degrees Celsius. This verifies that the predominating isomer is meso indicating that the cyclic intermediate remained. Therefore, almost no error occurred within the reaction since the two melting points are…

My Element is the Most Important Element (Argon) •Atomic mass 39.948 •Atomic Number -18 •Gas at 298 K •Density-0.0017837 grams per cubic centimeter •Third Noble gas •Chemical Symbol-Ar •It is also obtained from the air as a byproduct of the production of oxygen and nitrogen •It is the third most atmospheric gas •Argon is colorless and odorless •Argon is non reactive and has no effect on living organisms •Makes up 1% of the air around •Argon is found in the earth’s crust…

The temperature at which enzyme activity is most effective is approximately at 40℃. This result was expected as this trial temperature was closest to internal body temperature, 38℃, and as catalase is present in all body organs (T. Fouad, Antioxidants). Temperature affects chemical reactions by increasing the kinetic motion of molecules and changing the rate of collisions between them. In lower temperatures, kinetic motion is decreased and there are not enough collisions between the molecules…

Introduction A blender generally consists of a plastic or glass pitcher that locks into a large base. Some of blenders are made of stainless steel. The lid of the pitcher has a seal that prevents the food or liquid from splashing out while the blender is in motion. The motor has varying speeds that turn either two or four sharp, stainless steel blades. The blades slice, crush and blend the contents of the pitcher..Blender is a must have kitchen equipment for nearly all families today, especially…

Although they may be oddly shaped, volumetric and Erlenmeyer flasks are closed-end air columns, and they abide by the conventional rules of resonance. When a rubber stopper is inserted into a flask some air is forced out of the flask, and the stopper seals the flask so the air cannot get back in. This creates an area of low pressure within the flask. When the stopper is quickly pulled out of the flask, the air rushes back into the flask because the pressure of the atmosphere is higher than the…

Purpose The purpose of this experiment was to collect three different fractions of a mixture of hexane and toluene at differing temperatures. From there, the fractions would be measured via gas chromatography to discover the percent composition of hexane and toluene in each fraction with the ultimate goal of having one fraction with mostly hexane, one with mostly toluene, and one with an even mixture of the two. Along with this, there is also the goal of redistilling one of the fractions in…

sources at solid because it took time to sublime that solid and turn it into gaseous state for diffusion sources. The best efficient way is to use a gaseous diffusions sources. We got 2 candidates PH3 and POCl3. PH3 has a little quirk that escaping gas cannot be extinguished and exposure to fire may cause containers to rupture. This is a high temperature furnace which we will have a fire hazard so it would not wise to use PH¬3 in this. The best candidate will be POCl3 although it is an…

In this figure (10°C trial), the two test tubes are clearly labeled with 1 and 7, test tube 1 contains the 1 cm³ liver and test tube 7 contains the 5 mL of hydrogen peroxide. these two test tubes are in a 250 mL beaker containing approximately 125 mL of tap water and ice. The thermometer was placed in test tube 7, which contains the hydrogen peroxide to measure the temperature of the solutions. The hydrogen peroxide was poured into the test tube containing to the liver and was observed.…

technique of recrystallization. This technique involves several steps, selecting an ideal solvent, dissolving the compound in a minimum amount of boiling hot solvent, filtering insoluble impurities while the solution is hot; crystallizing the purified compound, and isolate the pure compound by vacuum filtration . The unknown used in the experiment was #4, which were white crystals. In order to determine the ideal solvent we prepared two test tubes. Test tube #1 containing 0.106g of unknown…
