What is Acid Rain? First identified in 1872 in Sweden and studied in the U.S. beginning in the 1950s‚ acid rain is precipitation in the form of rain‚ snow‚ hail‚ dew‚ or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground. Sulfur dioxide (SO2) and nitrogen oxides (NO‚ NO2) are bi-products from burning fuels in electric utilities and from other industrial and natural sources. These chemicals react with water‚ oxygen‚ carbon dioxide‚ and sunlight in the atmosphere

and frequent innovations. As a matter o fact‚ after launching the 3G innovation‚ groups as Orange launched the EDGE revolution. Indeed‚ the 3G is characterized by a technology’s standard of mobile phone that is accessible to consumers since 2002. Thus‚ the EDGE revolution permits to complete the 3G innovation in 2005. The debit can reach 384 Kbit/s: this innovation has a real impact on the strategy of Orange and other companies who want to use new technologies to obtain new market shares. b) Social

Chapter 4: Nucleic Acids and the RNA World 1. 4.1 – What is a Nucleic Acid? * Nucleic acids are made up of monomers called nucleotides * Three components of a nucleotide: 1. Phosphate group—attached to the 5’ carbon 2. Sugar – carbonyl group and several hydroxyl groups 3. Nitrogenous base * The prime (‘) symbols indicate the carbon being is part of the sugar—not attached to the nitrogenous base. * Four different nucleotides‚ each of which contains a different nitrogenous

Abstract The objective of this experiment was to observe multi-step purification of benzoic acid after performing the extraction from a mixture containing benzoic acid‚ cellulose‚ and methyl orange. Recrystallization was done to remove impurities from the sample. The amount of BA recovered during recrystallization is much less than the extracted amount of BA. The difference between the pure and impure samples was observed by comparison of melting points. It was found that impure samples will have

Acid Rain Acid rain occurs when Sulphur Dioxide (SO2) is released into the atmosphere by electricity generation‚ motor vehicles‚ factories and by wildfires and volcanoes. Once released‚ the sulphur dioxide reacts with water to produce sulphuric acid. This has a pH of approximately 2-3 pH. This has a dramatic effect on water dwelling wildlife. Most water dwelling creatures can’t withstand water more acidic than pH 5. This causes the mass loss of life of animals such as trout‚ perch‚ frogs and mayflies

review only the topics that will be on the exam. Second‚ review these exam topics with the test in mind. What this means is that you must do content review in conjunction with working real exam questions. If you just do content review alone‚ then you’ll end up forgetting most of what you went over. However‚ if you work MCAT problems while doing content review‚ you’ll retain most of what you learned. Incidentally‚ the stuff that you retain will be the stuff that will be tested on the MCAT.
