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.
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.
Carcinogens are a class of substances that are directly responsible for damaging DNA, promoting or aiding cancer. Tobacco, asbestos, arsenic, radiation such as gamma and x-rays, the sun, and
It is very corrosive and causes severe burns. It is very harmful by skin contact or by inhalation of dust. This cocktail together is used for getting into the ground and then it contributes to global climate change creating air pollution. They argue that fracking harms the environment and can hurt other living species such as bird, and fish. All of this is true; however, natural gas is a cleaner burning fuel and it has other advantages.
Chemicals play an important role each day in our individual lives. Chemicals are used to make products that clean our homes, feed our families, drive our cars, and even heal our pain. The chemicals used to produce these essential needs can be found in the earth which is considered natural, and others are made by man (EPA, 2011). Although chemicals make life simple and efficient they can cause harmful effects to people, animals, and the environment if proper precautions are not taken while disposing of the product. When chemicals pose a threat in any way they are classified as hazardous.
During the process of fighting fires there is alot to be aware of such as thick smoke. Smoke entering your lungs can be a huge risk when it comes to your cardiovascular health. However each firefighter is given a face mask to help you to breathe and protect your lungs from the smoke. How protective are these masks? Alot of the masks contain center ventilation orifice allowing easy air exchange and helps prevent buildup of CO2(the thick smoke created by fire).
There is the possible pollution of air as well. Contamination could make anyone who depends on a healthy ecosystem to earn a living could become ill or potentially have their livelihood destroyed. This shows that hydraulic fracturing could be very dangerous. However, although there are negative effects to hydraulic fracturing, there are also positive ways to look at these technological breakthroughs. Hydraulic fracturing can and has helped many communities receive economic gains, thanks to the increase in gas and oil production.
Large amounts of methane and other poisonous gases released into the air from the gas wells contribute to heavy air pollution and global warming. Fracking has been linked to movement of radioactive materials and heavy metals from the underground layers of the earth to the surface through flow-back
Sulfuric Acid is a strong acid that exists as a colorless oily corrosive liquid and is made by reacting sulfur trioxide with water. This is most commonly found in batteries, manufacture of fertilizers, explosives, detergents, dyes and other different chemicals. Sulfuric Acid is very dangerous to humans as it can cause respiratory tracts of humans and other animals while doing some major damage to plants that helps provide oxygen for us. Ground-level ozone is a secondary air pollutant formed when sunlight triggers reactions between nitrogen oxides and volatile hydrocarbons. If a human inhales ground-level ozone it can cause chest pain, throat irritation, and congestion.
