Barium

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…

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…

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…

such as: blood protein levels, sedimentation rate, mineral levels, red blood cells, white blood cells, and stool samples to rule out blood and infectious microbes. Imaging studies and endoscopies are also used to diagnose CD. These images may include barium x-rays and other types of x-rays. CT scans, colonoscopies, sigmoidoscopies, and capsule endoscopies are other forms of…

Introduction Gastric volvulus is a rare but potentially life threatening condition that is defined by the pathological rotation of the stomach. There are many factors that contribute to the pathophysiology of this condition, for example laxity of the gastric ligaments. Gastric volvulus can be categorized according to the axis of the rotation and may result in an organoaxial, mesenteroaxial, or combined volvulus of the stomach1. This condition can be primary or secondary, with secondary being…

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…

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…

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.…

times of war. Atomic bombs have been used in wars such as Hiroshima, Nagasaki, and some of the Pacific War, and World War II. The bombs have resulted in thousands of tragic fatalities. When the atom is split, it is not destroyed, but it is split into barium and a krypton nucleus. An atom can never be completely…

partake in other "geoengineering" activities. (Meghan, 2014). • Chemtrails are not just produced by aircraft, but also by antique cars that exceed 200 mph (Prothero, 2014). Some claim that chemtrails are purposely releasing toxins, such as aluminum or barium. Although this is true, tests indicate that these are particularly normal for aircraft carrier condensation. In order for chemtrails produced by aircraft to become significant, it would take a plane to run “2,700 times as many 747s as have…
