PRELIMINARY CHEMISTRY ASSESSMENT TASK 1. Identify the sources of pollution which accompany the combustion of organic compounds and explain how these can be avoided. Combustion refers to the burning of a substance in oxygen. It is a process in which a self-sustained chemical reaction occurs at temperatures above those of the surroundings. Combustion of organic compounds can result in detrimental impacts on the environment such as the generation of acids and production of carbon monoxide, particulates and soot.
C1.4.3 Hydrocarbon fuels Additional guidance: a) Most fuels, including coal, contain carbon and/or hydrogen and may also contain some sulfur. The gases released into the atmosphere when a fuel burns may include carbon dioxide, water (vapour), carbon monoxide, sulfur dioxide and oxides of nitrogen. Solid particles (particulates) may also be released. Candidates should be able to relate products of combustion to the elements present in compounds in the fuel and to the extent of combustion (whether complete or partial). No details of how the oxides of nitrogen are formed are required, other than the fact that they are formed at high temperatures.
Some of the dissolved carbon dioxide remains in the water, the warmer the water the less carbon dioxide remains in the water. Some carbon dioxide is used by algae and phytoplankton through the process of photosynthesis. In the natural carbon cycle, there are two main processes which occur: * Photosynthesis = plants use carbon dioxide and produce oxygen. * Metabolism = oxygen is used and carbon dioxide is a product Humans impact the carbon cycle during the combustion of any type of fossil fuel, which may include oil, coal, or natural gas. Fossil Fuels were formed very long ago from plant or animal remains that were buried, compressed, and transformed into oil, coal, or natural gas.
For example, in Kalkaska County the oil and gas industry is big and contractor jobs are tied to fracking. There are enough fossil fuels “locked” in bedrock shale formations under North American soil to make the United States energy independent, and a net exporter of oil and gas, in the near future. Natural gas releases fewer carbon emissions than coal as we use it for our vehicles and home. Although fracking can be pretty good there are some negative factors to it. A major negative is that companies aren’t obligated to disclose the chemicals they use for the process meaning if something goes wrong it will be hard to figure out the problem.
Nuclear waste must also be stored for a very long period adding to the cost. Nuclear has medium environmental impacts due to the energy required to mine transport and process nuclear fuels creating CO2 emissions, and nuclear waste can be hazardous and harmful to the environment if not properly stored, as it can be hazardous and prone to disasters it also has very low social acceptability. Coal is the most abundant, easily mined fossil fuel, it is also very cheap to set up coal fired power stations, this means it has very low economic costs. It produces large volumes of CO2 and other dirtier greenhouse gases and a pollutant meaning it has very high environmental impacts. It also has high social acceptability as it is cheap, not dangerous and not power plants are in industrial areas away from homes so it has limited NIMBY issues and noise, light and visual pollution.
The effects of their use on the environment can be far reaching and detrimental to health of humans, animals, and other organisms that inhabit the earth. Eventually, these fossil fuels will run out. Finding alternative ways to produce power is an endeavor that is
Coal, natural gas, and oil are burned for energy in many ways such as cars and power plants. Forest burning for deforestation also causes C02 emissions. C02 emissions are harmful to the planet and cause the planet to heat up. Global warming causes worse weather conditions in the world amongst other issues. With so many issues that can arise with a hotter Earth, I believe this to be a major issue that needs to be addressed.
It also releases large amounts of methane which is considered an earth warming gas. Just like methane , greenhouse gases are released. Greenhouse gases add to the greenhouse house affect which causes global warming. The gases help trap heat making temperatures. The raise of the temperature has been affecting humans and animals.
Solar energy is a non-pollutant, cost effective, maintenance free, life span of up to 40 years; however the upfront cost is enormous, and not everyone can afford the cost to put the stylish panels on their roof tops. Many jobs would be lost at the oil field however more jobs would be created by installing other methods of
Fifty billion dollars is a lot of money when it comes to our economy now days. ANWR has enough oil, in fact nine to sixteen billion gallons, producing 1.1 million barrels a day for the next 25 years (NPR). Producing that amount of oil, and keeping all the spending money in side of the united states, and receiving money from people who might purchase our oil, would lead the economy to take a step forward, instead of staying in the same spot. Drilling in America would also lower the oil prices, which seams obvious. If we drill here, as I have stated, we spend less money; by spending less money, we can keep more money here from taxes and shipping costs, lowering the prices at the pumps, because the oil companies will not be getting taxed as much, leaving them room to drop the prices.
