The Activation Energy for the Molecule of HALS Reaction using GAUSSIAN 09 via the WebMO Interface - 4.0 Discussion : 4.1 Hypothesis The hypothesis of the reaction, there was similarity by comparing the compound in case nitrogen was neutral and protonated. Table (1) illustrated that there was clearly different in the energy between two cases of that compound by 119 kJ/mole with basis set 6-311+G(d,p) and 128 kJ/mole with basis set 6-31 G(d) and similarly in level of theory(B3LYP). Therefore, the protonated nitrogen of the HALS molecule had higher energy than the neutral nitrogen through the potential energy of the reaction....   [tags: Energy] 877 words

Temperature's Affect on Chemical Reactions - There are many factors that affect the products of chemical reactions. All reactions are affected in a different way when exposed to these agents. Temperature is just one of many factors that can change things about reactions. When exposed to temperature change, the activation energy of a reaction can be met much more quickly (or slowly) than it would have been. As the temperature goes up, the rate of reaction increases. Temperature is a very flexible contributor to the rate of reactions and chemical reactions in general....   [tags: activation energy, physical chemistry] 1235 words

The History of Explosives - As everyone knows, explosives explode; they require activation energy which sets off the explosion. However, many do not know that explosives are categorized into propellants and high explosives. Propellants burn in a rapid but constant fashion and the projectile is under a steady high pressure, while high explosives change in an irregular pattern and produces a shock that is violent and disruptive (Crystal 428). Ever since the first use of gunpowder, explosives have changed from being simple mixtures of elements that could be ignited into something that had become highly destructive, dangerous, and complex....   [tags: Explode, Activation Energy, Explosions]

Theoretically, the more bonds to break, the more energy released. (biofuel.org.uk, 2010) Combustion ensues when a fuel is reacted with air. Complete combustion occurs when all of the bonds in a molecule are broken, releasing the maximum amount of energy. Complete combustion is referred to as the excess. However, in reality this rarely occurs.

Solar Energy: A recyclable means to an end - Gas like water is a natural reserve and the general public often forgets that just because we see it and use it everyday does not mean that it is forever abundant. “Natural gas has limited reserves and is subject to erratic price fluctuations. (Indeed, natural-gas prices have tripled since 1998) (Wright-p.385). If we are not careful and responsible, these resources can be depleted completely and we can destroy the earth at the same time. There is however a natural resource that is forever unlimited and that can supply us with almost the majority of our energy needs: The Sun....   [tags: Energy]

Nuclear Energy: Are the Benefits Worth the Risk? - Nuclear energy has, for some time, been a controversial issue. With incidents like that of Chernobyl, Three Mile Island, and the more recent complications caused by the earthquake and tsunami Fukushima reactors in Japan, concern about the safety of nuclear energy has become a major issue. A lot of this concern probably exists because of a lack of information and education about both radiation and its effects. It is my belief that nuclear power is no less safe than any other form of energy generation, and can produce significant amounts of power....   [tags: Energy ]

Environmentally Friendly Energy Future in Australia - Introduction The development of industrialisation and advanced technology has played an important role in increasing energy consumption in the world. This increasing use of energy pattern has also brought a number of both environmental and human health problems such as greenhouse emissions. Despite this fact, most of the world’s energy is produced using fossil fuels such as coal, oil, and gas. For example, in 2008, Australian energy production was 302.13 million tonnes of equivalent oils (Mtoe) while the consumption of energy was 240.40 terawatt hours (TWh) and these amounts of energy consumption and production caused 397.54 million tonnes of carbon dioxide (Mt CO2) emissions to the world’s...   [tags: Energy ]

Fossil Fuels and Alternative Energy Sources - Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas. They all take millions of years to form, so they are considered to be “non-renewable”- eventually, the fossil fuels will all be used up. One dangerous biological effect of using fossil fuels is ocean acidification. Extracting and transporting fossil fuels can also be very dangerous....   [tags: Energy] 2001 words

Hawaii’s Renewable Energy Future - “By 2020, Hawaii is aiming to generate 20 percent of its energy from non-fossil fuels” (Brown et al. 2008, 11). According to the National Renewable Energy Laboratory (Arent et al. 2009, 1-2), petroleum accounts for 90% of Hawaii’s energy consumption and 75% of their electricity. Since Hawaii has no pipelines or oil fields, they are forced to import petroleum to accommodate their energy needs (Arent et al. 2009, 1). Hawaii is disconnected from the rest of the United States, which means that Hawaii has to take care of its own energy needs (Croucher 2010, 79).How can alternative energy sources reduce the need to import of petroleum....   [tags: Energy ]

Energy Production Debate - In the future un-renewable resources, like fossil fuels, will be non-existent. “Fossil fuels currently account for 83% of the U.S. energy supply” (LePoire, 2011). The U.S. is fighting a battle to reduce the amount of fossil fuels it uses, which is currently at a staggeringly large level. As well as not being a renewable resource, fossil fuels are a heavy contributor to CO2 emissions and the effect they have on global climate change (Pollin, Wicks-Lim & Garrett-Peltier, 2009).When fossil fuels do deplete completely, there has to be something to take the place of that energy production....   [tags: Energy ]
