Experimental Thin Layer Chromatography The amino acid standards used in this experiment were Alanine‚ Glycine‚ Serine‚ and Histidine. These standards and the unknown were separated by performing a method of chromatography. Thin layer chromatography (TLC) was performed by using a mobile phase and a stationary phase. The mobile phase was a nonpolar solvent composed of ethanol

When people think of air pollution and ozone depletion they almost always and only think of exhaust from cars and factory smoke stacks but that is another reason this article stood out which is the fact it states in that “The electricity sector is responsible for more than a third of greenhouse

warming. Carbon dioxide‚ during the burning process‚ creates a layer in the atmosphere which stops the heat from escaping into the space. When the heat can’t escape it comes back to the earth and causes warming that leads to melting of ice caps and as result of it the sea level may raise and some part of the land such as Japan or California can be flooded. Another problem that we have to face with is the size of ozone layer. The ozone layer that protects the Earth’s surface from harmful ultraviolet

audience that the "ozone hole" is not caused by man and therefore requires no policy against CFC’s. Central idea: The ozone layer/"hole" is caused by fluct. in the environment and CFC’s are little if any of the cause of ozone depletion. CFC’s are very heavy‚ they stay close to the ground and do not affect the stratosphere. Volcano’s put out approx 10X more times chlorine than man produces. Ozone Center of WA states: "The 1991 volcanic eruption of Mount Pinatubo led to temporary severe ozone depletion but

Introduction: When air gets polluted with dust‚ smoke‚ motor vehicles‚ mills and factories etc. is called air pollution. We know that air is an important element of our environment. But it is a matter of great regret that it is being polluted day by day in different reasons. Causes of Air pollution: There are different kinds of reasons of air pollution. The causes of air pollution are described below. 1. Using poison in agriculture: In agricultural sectors‚ farmers often use insecticides

ENVS0110 This week’s readings had the common theme of global climate change. All of these sources encompassed different aspects of climate change. John Houghton’s “The Greenhouse Effect” was more factual and scientific. S. Goerge Philander’s “The Ozone Hole‚ A Cautionary Tale” was informational too‚ however‚ the piece also discussed global reactions to the rapid climate change. Thomas R. Karl and Kevin E. TrenBerth’s “Modern Global Climate Change”‚ focused on the intensity of anthropogenic influences

Warming happens naturally however because of the human race we have increased how fast it’s happening. There have been many meetings with other nations to control the amount of carbon-dioxide released. Along with the release of CFC’s that hurt our ozone. The Ozone deflects 99% of the UV rays which cause a variety of disease. We all know that it is bad but because most people don’t know what to do to help their environment. Well it’s the simple things like recycling and reducing your carbon-foot print.
