Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to

Addicted To Oil The United States uses nearly a quarter of the world’s oil. This would not be a problem if the U.S. had a large oil reserve but it only has 3% of the world’s reserves for 4% of the population (Pickens). This huge dependence on oil is costing us economically and also threatens our dreams. The United States needs to become more energy independent by using sources other than oil. Many alternative sources are available but renewable sources provide the brightest future.

includes crude oil and refined petroleum products‚ that we consumed during 2009. Just over half of these imports came from the Western Hemisphere. Our dependence on foreign petroleum is expected to decline in the next two decades. In 2009‚ the United States produced 11% of the world’s petroleum and consumed 22%. The United States consumed 18.8 million barrels per day of petroleum products during 2009‚ making us the world’s largest petroleum consumer. The United States was third in crude oil production

advancements in all aspects of life whether it be scientifically or creational (creatively). Technology is part of every person’s life and without it we wouldn’t be able to move forward. So why do we want to move back? Although many of us are for technology and the new scientific and social developments that come with it but there are others that are not so fond of it and complain that technology is taking over our lives and some people argue that technology may be the cause of our lack of social skill

Gas Laws Name Institution The 3 Gas Laws Introduction The three gas laws include: Gay-Lussac’s law‚ Boyle’s law and Charles’ law. When combined with Avogadro’s law the three laws can be generalized by the ideal gas law. Gases possess observable properties which include‚ mass‚ pressure (P)‚ thermodynamic temperature (T) and volume (V). These properties are related to each other and the state of a gas is determined by their values. The three laws are derived from these properties. Discussion
