point will evaporate and rise into a distillation apparatus. The newly formed gas will travel through the apparatus until it is cooled down, at which point the gas will not be able to maintain the energy needed for this specific phase, and will begin to condense back into a liquid. The same process will occur with the second liquid, the only difference being that it needed a higher temperature in order to transform into a gas. The two new liquids will each have a higher percentage of the unknown compound

the ideal gas law. By vaporizing a small sample of acetone and condensing it into liquid while measuring temperature, pressure, volume, and mass, the number of moles of the gas substance and its molar mass can be calculated. An accurate calculation of the moles of acetone gas was allowed due to the hole in the foil of the test tube, which ensured that excess oxygen was driven out of the test tube and only acetone gas was left. In order to accurately calculate the mass of the acetone gas, the test

CHEM 4230, Tuesday Section Lab Memo Date: September 12, 2015 To: Dr. Stefanie Whitson From: Kerri Keller Lab Partners: Siri Alay, Landon Carver Subject: GC-MS of a gas, gas simulant, and octane booster Summary: Gas Chromatography- Mass spectrometry (GC/MS) was used to identify the major components of gasoline, a gasoline simulant, and an octane booster. GC-MS is an analytical method that separates mixtures into individual components and uses mass spectrometry to identify each component by

Climate change is caused by greenhouse gases changing the atmospheres surface temperature. Greenhouse gases such as carbon dioxide are increasing the overall temperature of the atmosphere every day. But climate change causes more problems than just temperature's rising. Climate change also affects wind patterns, sea levels, precipitation patterns, and air pressure. Global warming contributes to climate change as seen in the recent hurricanes that have affected many places in the world today. Hurricanes

everyday activities like driving a car or things businesses do daily like burn fossil fuels or certain businesses like cutting down trees all add carbon. Cars emit around 24 pounds of carbon dioxide and other global-warming gases for every gallon of gas. Many car companies are finding ways to solve it by creating cars that run on electricity or energy. A big new brand, named Tesla, has started coming out with cars like that for expensive prices but significantly lowered them when they realized how

Retention time is the time required to elute a solute to a maximum from a column. It indicate how long it takes for a chemical compound to come out of the HPLC column. In HPLC chromatography, the polar solvent will be attracted to a polar solute that bound to the stationary phase. The polar solvent compete with stationary phase for the bound state. Therefore, the higher the polarity of the solute, the more easily it being affected by the solvent. This cause the solute not able to retain by the stationary

and negative effects have made by human-beings. One of the first subject people learned is that there are several causes of global warming. However, one of the most effective reason is Carbondioxide gas which most come from the combustion of fossil fuels and forests. Another obvious gas is chlorofluorocarbons which is called CFCs, are produced from fridges and air-conditioning machines. These greenhouse gases create greenhouse effect which is the process that raises the temperature of air

either flared on site. Flaring is the process where unwanted gasses are pumped up a stack and burned creating other, less harmful gas. Cold venting is the alternative to flaring: it is where the gas is vented to the atmosphere, depending on location and surroundings. In an area where houses are nearby methane is normally burned off in a flare to produce a less poisonous gas, rather than venting pure methane. When methane is released from the flow-back and flaring is not an option, it is vented into

3.6 Amoco Company Equation for SK Z-Factor Chart Amoco Company uses the Hall and Yarborough z-factor determination method And can be defined as follows: Ζ=[(0.06125P〖ρr〗^t)/Y]EXP[-1.2(1-t)^2 ] 2.3.7 Gopal Best-Fit Equation for SK Z-Factor Chart: Gopal’s correlation for z-factor estimation was developed by dividing the Standing-Katz chart into two parts by drawing a line isobarically for PR up to 5.4. For various Tr values, several z-factor values were tabulated isobarically for Pr up
