2.1 Classes of Hydrocarbons: Aliphatic | Aromatic (aka Arenes) | Alkanes, Alkenes, Alkynes | Benzene is an example | Alkanes: All bonds are single bonds Alkenes: Contain at least one C-C double bond Alkynes: Contain at least one C-C triple bond 2.3 Bonding in H2: The Valence Bond Theory Sigma Bond: orbitals overlap along a line connecting the atoms 2.4 Bonding in H2: The Molecular Orbital Model Bonding Orbital and antibonding orbital produced 2.5: Introduction to Alkanes: Methane, Ethane and Propane Alkanes: CnH2n+2 2.6 sp3 Hybridization and Bonding in Methane Sp3 Hybridization 2.7 Bonding in Ethane CH3= Methyl Bonds with sigma bond 2.8 Isomeric Alkanes: The Butanes n-butane: four carbons are joined
This process is fractional distillation. c) Some properties of hydrocarbons depend on the size of their molecules. These properties influence how hydrocarbons are used as fuels. boiling points viscosity flammability. C1.4.3 Hydrocarbon fuels Additional guidance: a) Most fuels, including coal, contain carbon and/or hydrogen and may also contain some sulfur.
From the first automobile to the first cell phone, technology is a never ending mechanical and scientific evolution that is designed to benefit us and make life easier. Every day we rely on technology to help us achieve our goals quickly and efficiently while using the least amount of energy we possibly can. There is an extremely large dependence on these technologies and their functionality. This dependence and reliance on the constantly growing technological advancements around us is argued by some as harmful and dangerous, ultimately becoming damaging. In The Illustrated Man by Ray Bradbury, the idea of technology and its harmful long term effects is brought up on many occasions.
It shows that the oil and gas industry has had several breakthroughs with technology, including hydraulic fracturing. These breakthroughs have found ways to make hydro fracking more environmentally friendly and cost efficient. With any technological developments, there are consequences. For example, there is the possibility of polluting the water supply with chemicals. There is the possible pollution of air as well.
SO2, sulfur dioxide effects our trees and water systems and is the prominent cause of acid rain. Mercury- when Mercury enters our water systems it becomes harmful to our ecology (fish, plants, animals etc) and effects anyone who consumes part of the food chain. Nitrogen
Because they are hazardous. As in documentary they showed in an ad that fracking is safe. But what they mean by safe? If water, air and noise pollution are created by fracking then how it is safe! Fracking also created huge natural losses such as it crates pollution, destruction of forests to create its pipe lines.
“While [hydraulic fracturing] can help provide energy for America's future, it also poses a new dangerous threat to wildlife and the environment. Toxic chemicals are used during fracking that can infiltrate and contaminate habitat, waterways, and even the drinking water that people and wildlife depend on” (1996-2013). Evidently, “some opponents of oil and natural gas production claim that fracking has serious environmental consequences. The truth is, while all development has challenges, hydraulic fracturing technology has a strong environmental track record and is employed under close supervision by state, local and federal regulators. Studies by the Environmental Protection Agency (EPA) and the Ground Water Protection Council (GWPC) have confirmed no direct link between hydraulic fracturing operations and groundwater contamination.
Conversely, Chemical plants can contaminate the pure water or create harmful diseases to humans and the Earth. The West Virginia chemical spill demonstrates the dangers chemical plants pose to our environment, and it is important to understand the devastating
This concept is best exemplified by the causes and effects of Henry Ford’s Model T. Undoubtedly, The Model T was a great advancement in Technology, but it also marked a major turning point in the advancement of the middle class in the United States. The Model T improved the lives of rural families, urban middle class families and industrial worker and also created a more defined
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.
