Organic chemistry is the study of essentially all substances containing carbon. Organic compounds that contain only carbon and hydrogen are called hydrocarbons. The simplest hydrocarbons are the alkanes which contain only single covalent bonds. Methane is the simplest alkane. It is also the major component of natural gas. Methane contains only 1 carbon in the molecular formula and the structural formula. There is ethane which is 2 carbons‚ propane that is 3‚ butane which is 4‚ pentane which is 5

Technetium-99 Technetium-99 (Tc-99m) is used tens of millions of times annually. Approximately 85% of diagnostic procedures in nuclear medicine use this radioisotope. Making it the most common radioisotope used in diagnosis. Technetium-99 is used as a radioactive tracer and is detected in the body by gamma cameras. Technetium-99 is produced by bombarding Molybdenum with neutrons‚ producing Molybdenum-99. This then goes through a Beta decay with a half-life of 66 hours and produces Technetium. Technetium-99

harmful it should be stored away from human populated areas. If nuclear waste is harmful it should not be stored by humans‚ but in less to non-populated areas. “Spent nuclear fuel remains highly dangerous for prolonged periods. It has long lived radioactive materials in it that can contaminate the environment and harm public health” (USA Today). Thousands of Americans are exposed to nuclear waste sites across the country. And if we do not take action to find somewhere else to store this waste. Many

Nuclear Waste by Richard A. Muller Nuclear waste is a radioactive waste that is dangerous‚ and a fair percentage of people would agree on this topic. However‚ is it really dangerous or is it just harmful to an extent? In society‚ many debates are held over trying to prove to the world that this substance is harmful. In the essay‚ “Nuclear Waste‚” Muller states clearly that he sides with the anti-nuke of the debate and how he pinpoints the facts of nuclear waste with great persuasion. Yet‚ it is

1. Environmental impacts of nuclear waste. Nuclear waste or radioactive waste is the residue of nuclear reactors‚ nuclear researches‚ nuclear projects and nuclear bomb reaction. Nuclear wastes‚ also known as spent fuel‚ are dangerously radioactive and could exist for thousands of years. The release of nuclear waste from its reactor could easily cause a lot of diseases like acute radiation sickness. The injection of nuclear waste to underground water causes water pollution and could contribute

remained the same since they were formed. However‚ some nuclei are unstable and spontaneously release energy in the form of a Helium nucleus (α Alpha)‚an electron (β Beta) and γ Gamma rays. These nuclei are known as radioactive and it’s not possible to predict when a particular radioactive nucleus will emit this energy but a large number of materials are said to have a ‘half life’. The half life is the time it takes for half the nuclei to emit their radiation. 1. Describe and compare the nature
