  • Atomic Bombs In H. G. Wells's Novel, The World Set Free

    Within the first few decades of the 20th century, the science of physics was completely reformed with new understandings of the nature of atoms. In 1898 France, Paris, Pierre and his wife Marie Curie discovered a new substance within an ore of Uranium that they named radium that emitted large amounts of (as we now call) radioactivity. Ernest Rutherford and Frederick Soddy Identified that atoms can break down and turn into different elements. For example if a block of uranium were left alone for…

  • Hydrochloric Acid

    the chemical reactions that each compound undertook. The four following acids and bases were used to predict when a set amount of reactant would reach equilibrium: Hydrochloric Acid (HCl), H2SO4 (Sulfuric Acid), NaOH (Sodium Hydroxide), and Ba(OH)2 (Barium hydroxide). An unbalanced equation of each reaction was given so the balanced equation was then able to be calculated. These are as follows including the theoretical ratio between the acid and base: HCl + NaOH → H2O + NaCl 1:1 H2SO4…

  • CAT Scan Vs MRI Essay

    system, and rarely the skeletal system. These types of tissues are considered a thicker tissue and harder structures which only CAT scans can produce an accurate image compared to MRI. The practice includes a person drinking concoctions of iodine, barium, or receiving intravenous contrast dyes, then lying inside of a CAT machine and waiting for the scanner to process the cross sectioned images taken through x-ray bursts. Each of the concoctions or dyes stand out in because of the use of…

  • Inflammatory Bowel Disease Analysis

    What Is Inflammatory Bowel Disease? Inflammatory Bowel Disease is a term used to describe disorders in which the intestines become red and swollen, or inflamed. The two major types of Inflammatory Bowel Disease are Crohn’s Disease and Ulcerative Colitis. They are very similar, but the main difference in the two are the parts of the digestive tract each type affects. Crohn’s Disease is often found in the ileum of the small intestine, but can occur anywhere in the digestive tract (from the…

  • Adakite Research Paper

    Introduction Adakites are volcanic rocks that are diagnostic of high temperature, high pressure conditions, (Stevenson, 2005). Their composition ranges from felsic to intermediate, and are characterized by assemblages of plagioclase, and often amphibole, and are identified by their unique geochemical signatures. Adakite is named Adak Island, Alaska, where it was first documented,(Defant and Drummond, 1990). They are often formed through the partial melting of a young subducting slab of…

    levels. Some substances that are detected in water could cause taste, color, or odor problems, but should not be a cause for health concerns since Maximum Contaminant Level (MCL) are met. These substances include lead, copper, fluoride, nitrogen, and barium. Coliform bacteria naturally present in the environment, are used as indicators of microbial contamination of drinking water. These bacterium are easily detected; although, coliform bacterium are not disease producers, they are often found in…

  • Emperical Formula Lab Report

    Introduction The purpose of this lab is to find the emperical formula of a compound made of magnesium and oxygen. We took a strip of magnesium and combusted it to figure out how much of the strip was magnesium by weighing the remaining ashes. The weight that wasn’t transferred to ashes was burnt off in the smoke as oxygen. To find the emperical formula, you had to take the average mass of both magnesium and oxygen and divide by the average mass to get the amount of mols in the compound.…

  • Environmental Effects Of Fracking

    The waste produced is treated in municipal sewage plants rather than in toxic waste facilities. Because of this improper handling of materials rivers and tributaries sometimes become contaminated with barium, strontium, and bromides. Other approaches used to contain the contaminated water are to simply pump it into oil wells or other locations that have been previously used for fracking. This is more of a temporary storage solution that is rather short-sighted…
