Goals The goal of the lab was to investigate the properties and structure of an unidentified compound that was discovered in a local landfill. The group was called in to help determine the chemical and physical properties of the compound so we can let the people of the town know so it can be taken care of properly with or without further precautions to be taken. Another goal of this project was to devise the synthesis of the unknown compound. Experimental Design In order to determine the…

The purpose of this experiment was to determine the identity of nine solutions using the results of reacting pairs of solutions in an organized systematic manner. Known solutions were used on the first day. The second day, the solutions were placed in code-labeled bottles. The reactions from the previous day were then used to help identify which solutions were which, by closely monitoring which unknown solutions mixed with other unknowns and how they reacted, such as: color changes,…

The paper I chose for the Case of the Term assignment is “A case of tolterodine poisoning”. Tolterodine (Detrol, Detrusitol) (CAS #124937-51-5) is an antimuscarinic drug that belongs to the class of drugs known as antispasmodics. Tolterodine is prescribed to treat urinary incontinence or overactive bladder by relaxing the muscles in the bladder. Tolterodine is marketed and manufactured by Pfizer. Antimuscarinic drugs inhibit the action of acetylcholine at muscarinic receptors. Tolterodine acts…

Water is one of Earth’s most precious resource. All living things need water. In this report we will be discussing which water is safe for drinking, how the quality of water is tested, where it is stored and collected, how it is purified and using an alternative supply to tap water. Safe water is water that will not harm you if you come in contact with it. This type of water is free from harmful micro-organisms and substances. This water would also have had to be tested and met certain…

it happened at the Alfred P. Murrah Federal Building. In this attack there was a total of 168 deaths, 19 were children that were in the day-care center that the building had, and more than 500 people were injured. The bomb was made with ammonium nitrate and fuel oil. This was the worst terrorist attack on U.S. soil until September 11, 2001. When the bombing happened it affected other buildings around. The explosion destroyed more than 300 other buildings around the immediate area. The event…

CHANGES IN CHEMICAL REACTIONS INTRODUCTION This practical experiment is based is based on the theory of Law of Conservation of Mass stated by Antoine Lavoisier. Antoine Lavoisier was a French nobleman who had a major influence on the history of chemistry and biology. Today he is considered to be the “father of modern chemistry.” In all his experiment he supported the Law of Conservation of Mass. Antoine stated this in his theory, “The law of conservation of mass states that mass can neither be…

Several accusations were made that manufacturers were incorrectly labeling the iron content on their products. The purpose of this experiment was to analyze the amount of iron in approximately one serving of Total Whole Grain cereal and in one iron tablet and determine if these accusations were true. The values collected would then be compared to the actual values for these products. Total cereal contains 100% of the recommended daily allowance for iron, and the iron tablet contains 361% of the…

Stormwater runoff brings many problems besides polluting the Bay. It causes a chain reaction of negative events such as killing the native life in the watershed, causing diseases in humans, polluting the air, and loss to the economy. It’s more than simply making the water look repulsive. Stormwater runoff hurts the Bay, and there are simple everyday actions citizens can do to benefit to the Bay. The government can only do so much to protect the Bay. Citizens can build ourselves, volunteer, and…

Specific Purpose To inform individuals about the importance of climate change, how it affects each and everyone of us. Introduction Humans have made extreme modifications to the earth 's environment in little more than a century, making climate change a serious issue ( Taylor 1999) The source for the expansion of climate change is from human activity. It has been proven that there is a correlation between human activity and climate change. As the human population increases the demand for…

ethanol for 30 min followed by 30% ethanol for 30 min. The gels were then sensitized for 1 min in 2% solution of sodium sulfite (Na2SO3) followed by rinsing three times with Mili-Q for 20 sec and were stained for 20 min in staining solution [1M Silver nitrate (AgNO3) and formaldehyde (HCHO)]. After staining, gels were rinsed thrice for 20 sec in distilled water and developed for 5–10 min in a developer [sodium carbonate (Na2CO3) and formaldehyde (HCHO)] and observed for the appearance of intense…
