Nitrous oxide - Laughing gas uses in modern society

Laughing gas, nitrous oxide used to be routinely given as a dental anaesthetic. This is no longer the case. Why not? What else is nitrous oxide used for?



Whippets

Whippets
In this research paper I will attempt to explain what whippets are. I will try to give the necessary information to show the benefits and possible side effects. I will discuss a brief history of the gas and how young adults obtain the chemicals to make ?whippets?.
Whippets are charge dispensers that deliver nitrous oxide as (en.wikipedia.org) describes. Nitrous oxide is a colorless, non-flammable gas. It has a slightly sweet taste and odor. It is non-toxic and non-irritating and when inhaled in small quantities can produce mild hysteria and giggling or laughter. That is why it is also referred as the "laughing gas". When inhaled in pure form it will cause death by asphyxiation because at atmospheric temperatures and pressure, the oxygen in nitrous oxide is not available to the body.



Energy - What You Need To Know About Bio Fuels

Agro fuel commonly as bio fuel is derived from a biomass. It can be a solid, liquid or gas fuel. Bio fuel is now a common means of decreasing the greenhouse gas emissions and is now used as fossil fuel alternative. It is eyed to replace fossil fuels in the near future. However, it was researched that though bio fuel reduces the greenhouse effect, the release of Nitrous Oxide from commonly used bio fuel contributes much to global warming.



Global Warming and Greenhouse Gas Emissions

Global Warming and Greenhouse Gas Emissions
Since the nineties, our gas emissions have increased so much, the atmosphere suffers the consequences. In my opinion it is do to the slothful citizens of our country. We have so many different benefits in the United States that we tend to become a glutton to items we do not need such as televisions in every room, also, significantly, more than one car. Oftentimes it leads to driving to the mailbox right in front of the house. Therefore, Carbon Dioxide, water vapor, and Ozone, and smaller greenhouse gases such as Methane, Nitrous Oxide, and chlorofluorocarbons are released when they could?ve been prevented. These gases collect a thick layer in the atmosphere. Out of the sunlight received on Earth, some of it escapes through space. With too much of the greenhouse gases in the atmosphere, some of the supposedly escaping heat is kept in Earth. Consequently, the heat causes very dire problems on our planet. ?Global warming can lead to floods/droughts, increasing ocean temperatures: rising sea levels, polar caps melt (coastal cities?), and crop/forest damage due to changes in precipitation? (notes 02/21). In order to avoid such horrible outcomes, gas emissions had to be improved; an agreement was made. In December 1997, one hundred and forty one countries met in Kyoto, Japan to negotiate the Kyoto Protocol.



Environmental Impact of Fossil Fuels

Environmental Impact of Fossil Fuels
Fossil fuels cause pollution, smog, and the greenhouse effect. Fossil fuels really do negatively impact our environment, especially when it comes to global warming, Although there is controversy over whether or not fossil fuels are causing the planet to warm, or whether it is warming naturally, there is significant research that supports the former hypothesis. When fossil fuels are burned, they emit different levels of carbon dioxide. The burning of fossil fuels has increased the amount of carbon dioxide in the atmosphere by a staggering twenty- five percent. It has also been implied that fossil fuels are associated with increased levels of nitrous oxide and methane, although they are not the main sources of these gasses. Carbon dioxide is a gas that traps heat in our atmosphere, and helps keep the planet at livable temperature. However, climatologists are now predicting that if the levels of carbon dioxide continue to increase, the temperature will rise and a number of different impacts can or will occur (Union). Among the many possible impacts of global warming, are more extreme weather events, rising sea levels, and the melting of glaciers. However, while researching, I stumbled upon a site that showed possible impacts, and where they would be most likely to occur. The key to the map had two different categories, ?Harbingers?, and ?Fingerprints?. Harbingers are ?events that foreshadow the types of impacts likely to become more frequent and widespread with continued warming? (Global Warming). Fingerprints are ?direct manifestations of a widespread and long-term trend toward warmer global temperatures? (Global Warming)



Solutions to Global Warming

Solutions to Global Warming
There are many solutions to reduce the amount of green house gases in the atmosphere, which causes Global Warming. A main culprit for global warming is the use of CFC?s (chlorofluorocarbons). If the use of CFC?s was reduced, the number of greenhouse gases will be reduced by a great deal (however there are many other thing that cause dramatic amounts of greenhouse gases including carbon dioxide and nitrous oxide). The items that contain CFC?s are regular house hold items, but they can have a devastating effect on the amount of greenhouse gases in the atmosphere. They are found in aerosols, plastic foam and fridges. However now that the scientists have a greater knowledge on the effect of CFC?s the government had banned the selling of objects with CFC?s in; and also great care is needed when disposing of older items containing CFC?s e.g. fridges. CFC?s are 40 times more effective as a greenhouse gas then carbon dioxide. So reducing the amount of CFC?s used will have a good effect on the atmosphere by causing less damage. This is something that all the governments across the world need to take into consideration before it is to late



Drug Influence on the Romantic Poets essay

Drug Influence on the Romantic Poets essay
Drug Influence on the Romantic Poets essay
The impact for the first generation after the Industrial revolution was depressing, terrifying and intoxicating to a scarcely bearable degree. The Industrial Revolution meant for the very first time a great mass of people no longer suffered through a life of brute labor just to avoid starving, to a life of consistent natural disasters and diseases. In this important time for England the new way of poetry took a place, the poetry that latter will find the name as Romantic Poetry. Great poets such as Wordsworth, Coleridge, Lord Byron, and Percy Shelley made huge impact on modern literature and have established outstanding legacy of English poems. However, not many of their readers notice the fact that number of Romantic poets where addicted to drugs such as opium and were finding their inspirations in opium houses.



Acidic Environment

Acidic Environment
Oxides of non-metals which act as acids Non-metals burn in air or oxygen to produce acidic oxides. The addition of water to soluble oxides produces acidic solutions. Oxides of non-metals which act as acids include:
Carbon reacts with oxygen when burnt to form carbon dioxide which
is acidic in nature. When dissolved in water, it becomes H2CO3
(carbonic acid).
CO2 (g) + H2O (l) â??H2CO3 (aq)
Sulfur burns in oxygen to give sulfur dioxide or sulfur trioxide
which is acidic in nature. When dissolved in water, it forms
sulfurous acid H2SO3 and sulfuric acid H2SO4 respectively.



Decomposition of Copper Carbonate

Decomposition of Copper Carbonate
Introduction Copper has two oxides, Cu2O and CuO. Copper carbonate, CuCO3, decomposes on heating to form one of these oxides and an equation can be written for each possible reaction. Equation 1: 2CuCO3 (s) à Cu2O (s) + 2CO2 (g) + ½O2 (g) Equation 2: CuCO3 (s) à CuO (s) + CO2 (g) Aim === The aim of this experiment is to prove which of these two equations is correct by measuring the volume of gas given off by the decomposition of CuCO3. Background Theory -??????? Cu2O is known as cuprous oxide. It is a red crystalline material, which can be produced by electrolytic or furnace methods. CuO is cupric oxide. This, a black powder, can be prepared by the ignition of suitable salts such as the carbonate, the hydroxide, or the nitrate of copper, or by heating of cuprous oxide*. The planning of this experiment requires previous knowledge about the mole.



The Effects of Global Warming

The Effects of Global Warming
Global warming is one of the problems and one of the human causes in the world that people are facing to protect their children, homes and the world. Many countries which have large number of factories have decided to stop global warming by stopping gasses, Co2 and other poisonous gases such as greenhouse gas. Global warming is defined as the gradual rise in the temperature of the bottom layer near to the Earth?s surface from the atmosphere surrounding the earth and it also defined as the change in temperature, wind condition and sea rate due to pollution in the world.
Increasing greenhouse and methane gas is causing this rise of temperature. Moreover, methane is resulted from microbial interaction in rice fields and ruminant livestock and burning of biomass (trees, plants and animal waste), also produces water swamps muddy. In addition, there is methane gas called oxide nitrous also consist of microbial interactions occurring in water and soil and the Group of chlorofluorocarbon gases which cause erosion of the ozone layer, and finally ozone gas, which consists in the lower atmosphere. Moreover, increasing pollution rate and gasses could change the thermal energy from the environment.
The aim of this project is to explain global? warming effects and also to explain how could the global warming be decreased by using other sources for energy, for example solar energy and wind power instead of oil and coal that effect rising temperature and pollution in the world. The last part is to compare and contrast between solar energy and wind power.
