September 10th‚ 2013 EXPERIMENT 1 LEARNING BASIC OPERATIONS: THE EFFECT OF PH ON A FOOD PRESERVATIVE Purpose: The purpose of this experiment was to investigate a competitor’s claim that the food preservative‚ sodium benzoate (C6H5COONa)‚ made by Fresh Foods International (FFI)‚ changed into a new substance in stomach acid. Stomach acid has a pH between 1 and 3 due to the hydrochloric acid content. Based on the net equation given in the book as well as the solubility of the product our hypothesis

cocaine may make it easily identifiable among other substances. The chemical property of cocaine is that it is reactive to cobalt thiocyanate and as a result it produces a blue-colored product (Girard‚ 2007). There are some other substances that also produce the same colored residue with reaction to the chemicals used for substance identification. For example; in reaction to cobalt thiocyanate‚ a blue-colored product similar to that of cocaine is produced by lidocaine‚ benzocaine‚ and procaine. Therefore

issues associated with biological corrosion of different kinds of implants used as cardio stents‚ orthopedic and dental implants. As the materials used for these implants are manifold starting from metallic materials such as stainless steel (SS)‚ cobalt chromium‚ titanium and its alloys‚ bioceramics‚ composites and polymers are in constant contact with the aggressive body fluid‚ they often fail and finally fracture due to corrosion. The corrosion behavior of various implants and the role of the

Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

breathtaking ever seen. Every rock protruding out made the water grasp for something in the distance as it fell out of the sky. The splashes emerging out of the water was steam coming off the ground on a cold day. The clouds covered the clean cobalt color soaking the sky. The clouds were small puffs of cotton floating in the sky. They floated in the sky‚ making the picture that much better than it was before. The air was vacant of birds as the noise ear-shattering. Every glimpse of the sky

It’s here in a student’s journal‚ a blue confession in smudged‚ erasable ink: “I can’t stop hoping I’ll wake up‚ suddenly beautiful‚” and isn’t it strange how we want it‚ despite all we know? To be at last the girl in the photography‚ cobalt-eyed‚ hair puddling like cognac‚ or the one stretched at the ocean’s edge‚ curved and light-drenched‚ more like a beach than the beach. I confess I have longed to stalk runways‚ leggy‚ otherworldly as a mantis‚ to balance a head like a Fabergé

During the 1970s‚ an increased demand for copper and cobalt attracted Japanese investments in the mineral rich southeastern region of Katanga Province. Over a 10-year period‚ more than 1‚000 Japanese miners relocated to the region‚ confined to a strictly male-only camp. Arriving without family or spouses‚ the men often sought social interaction outside the confounds of their camps. In search of intimacy with the opposite sex‚ sometimes resulting in cohabitation‚ the men openly engaged in interracial
