Barium Swallow A Barium swallow is a radiography contrast technique performed to visualize the esophageal portion of the Upper Gastrointestinal tract. Contrast Medium is taken orally and the lumen of the Esophagus is fluoroscopically visualized. Standard X-ray films are normally taken prior to administration of the contrast medium and these are useful in detecting perforation‚ presence of radiopaque foreign substances and gastric wall thickening. Oral contrast mediums‚ such as barium sulfate highlight

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

Determination of Water in a Hydrate DESIGN – Aspect 1: Defining the problem & selecting variables Research Question: What percentage of Copper Sulfate Hydrate is water? Background Information: There are many ionic compounds that contain one or more waters of hydration in their formulae. They exists either in anhydrous or hydrated form. Most anhydrous compounds have a strong tendency to absorb water from the humidity in the atmosphere and shifts into a hydrated form. Because of

A) January 18‚ 2011B) Empirical Formula C) The purpose is to determine the empirical formula of a metallic oxide. D) Pre Lab Questions: After heating the metal‚ the crucible and contents should mass less than it did before it was heated. This is because heating the crucible may rid of other residue that was left in it; bringing it a to a constant mass. A yellow flame will deposit soot on the crucible. This would be a problem because the soot left on the crucible would vary from our constant

Barium Research Paper Mr.Martin Block 1 May 18th‚ 2012 Abstract Barium was discovered in 1779 by Carl Scheele‚ but was isolated for the first time in 1808 by an English chemist by the name of Sir Humphry Davy. Barium is commonly found as BaSO4. Things that glow in the dark are made from Barium. Barium has many uses and plays a big role in our environment today. Barium can be found almost anywhere in the environment because it is produced there naturally and sometimes affects the environment
