  • Barium

    503 Words  | 2 Pages

    Barium is a soft, heavy, silver-colored metal element. This element does not have very many uses outside of the laboratory, but it combines easily with other chemicals to form compounds used for important industrial uses. For example, Barium carbonate is used in the manufacture of ceramics and special glass, and also to purify certain chemical solutions. It is also an ingredient in clay slurries, also known as water muds, used in drilling oil wells. Barium titanate is used in sonar detectors and

  • Barium Sulfate and the Gastrointestinal Tract

    2028 Words  | 5 Pages

    years barium sulfate has proven to be a successful contrast agent for examination of the gastrointestinal tract. Though the road to discovery was long and relentless at times, when it finally found its niche in medicine it was only to the advantage of the physicians and patients today. There are many new diagnostic tools in radiology today that have led to the questioning of barium studies’ place in medicine and whether it will remain there long. And to what cost it will take to keep barium around

    as we know it. Without them, many things that we both love and need would be gone. These remarkably diverse yet very similar elements that make up the alkaline earth metals family are: Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra). Although this family is often overshadowed by the infamous alkali metals, you will soon learn how spectacular and brilliant these metals really are and their value to human life. The alkaline earth metals are an interesting

    earlier studies had not picked up. While passing current through the cathode ray, other rays were being given off that passed through all everyday matter such as wood, aluminium and paper. Roentgen further observed a surface he had coated with barium Platinocyanide that was placed outside of the cathode discharge tube would still emit light, despite the fact that it was concealed from the light of the discharge. The conclusions that Roentgen came to were that a new type of radiation had passed

    IBS seek help from a gastroenterologist. A gastroenterologist is a doctor who specializes in the digestive system. Tests to diagnose IBS might include lab analyses of feces and barium X-rays of the lower digestive tract. For a barium X-ray, a patient drinks a special kind of liquid drink that contains barium. With the barium, the doctor can see how the liquid flows through the digestive system. A doctor may also perform a sigmoidoscopy. This is an instrument on a long thin tube that is inserted through

    Biology: Separation of Proteins Lab Report 1: Separation of Proteins Abstract/Summary: “Proteins account for more than 50% of the dry weight of most cells, and they are instrumental in almost everything organisms do” (Campbell, 1999). The significance of proteins to the continuation of our biological systems is undeniable, and a study of how to quantify proteins seems an appropriate introduction to our studies of biology. In order to study proteins we must first know how to separate then quantify

  • Analysis Of Barium Hexaferrites

    generally represented as (MeO.6Fe2O3), where Me is divalent metal such as Sr, Ba, and Pb or a mixture of these [12]. Barium hexaferrites (BaFe12O19) with a magnetoplumbite structure are well known as hard magnetic materials which are based on iron oxides. Hexagonal ferrites are referred to as hard because the direction of magnetization cannot be changed easily to another axis [].Barium ferrite possesses relatively high Curie temperature, coercive force and magnetic anisotropy field, as well as its excellent

  • Analysis Of Hydrate

    1055 Words  | 3 Pages

    Introduction Hydrates are compounds that form crystals that have water molecules in their structure. Barium chloride dihydrate, or BaCl2●2H2O is an example of this, with five water molecules for every one molecule of barium chloride. The water is called the water of hydration, and the dot between the barium chloride and the water molecules means that the two types of molecules are bonded together. The water of hydration is heated out of the hydrate when the temperature reaches above 100℃, since

  • The Digestive System and Achalasia

    561 Words  | 2 Pages

    Achalasia has the potential to cost the healthcare system a lot of money. There is no cure for Achalasia, therefore this is something that needs to be treated, sometimes as often as every 3 months (Dugdale, George & Zieve, 2010). When my mother has the surgery to stretch her esophageal sphincter, the average cost of her surgery ranges from $1,900 to $3,000, depending on anesthetics and whether or not they need to suck out food that is stuck in the esophagus. Insurance pays the majority of the cost

  • Barium-137m Half Life

    606 Words  | 2 Pages

    Introduction The purpose of the experiment was to conclude the half-life of Barium-137m. Half-lives are the time required for half of the remaining radioisotope to decompose into another element or becoming stable by releasing gamma-rays. Half-lives happen when an element is excited or in a meta-state (gamma), has too many neutrons (beta negative) or protons (beta positive), or has too many nucleons (alpha). To determine the half-life, arrange the formula of the number of half-lives that have elapsed

    this is done, predictions can be made. The table above, describes the solubility rules, these are used to decide whether a compound will be soluble, and then consequently to this reveal a precipitate. Barium sulfate for example is insoluble and if it was to be mixed with an aqueous compound, barium sulfate would be the precipitate. This is an example of how a prediction can be made, without physically viewing the experiment or given the results. It is also a way of identifying what the precipitate

The unknown sulfate solution was pipetted into a smaller beaker, acidified, heated, decanted through filtration, dried, cooled and weighed. What was found at the end of the result was Barium Sulfate precipitate which weighed 0.1783 grams. The concentration of the unknown sulfate solution was found to be 2.9385 g/L and its molarity was 0.0306M. Objective: To determine the amount of sulfate in an unknown concentrated solution by the Gravimetric

    that was emitted by the flame. In parts A and B, the results were the presence of the lead cation and the barium cation. Lead was identified in part a during step six when the solution turned cloudy and very yellow, indicating the presence of a lead precipitate. During part B, step 13, the solution turned foggy and yellow then settled into a white precipitate, indicating the presence of barium. These results were reasonable. The unknown solution was number 4. During part C, the BaCl2 solution emitted

    expand past the cardiac confines and can possibly mimic cardiomegaly (Kahn, 2008). A hiatal hernia is usually detected using three methods, an upper endoscopy also called esophagogastroduodenoscopy or EGD, a plain chest radiograph, and and upper GI barium series (Kahn, 2008). When using an upper endoscopy to diagnose hiatal hernia, the doctor will insert a small, lighted, flexible tube called an endoscope into the patient's mouth. The endoscope will allow the examination of the stomach, esophagus
