Constant Density: Displacement of Zinc and Tin Introduction: Density is the concentration of molecules within an object on relation to its size. The formula for measuring density is mass/volume. In the experiment preformed for this lab report‚ calculating the density of a regular object (a wooden block) and two other irregular objects (zinc and tin) were found by a process known as water displacement. The purpose of this experiment was to prove that the density of an object remains the same

liver transplant during their life. Most patients get chelation therapy to remove different amounts of copper. To remove copper penicillamine‚ zinc salts and/or trientine are used. Galzin is used to get rid of some physical symptoms of the Wilson’s disease. It is necessary to take 50MG of Galzine three times a day for it to work properly. Sometimes Zinc Acetate is given to block the absorption of extra copper. It is also necessary for a person with Wilson’s disease to have a different diet.

Keith Joung‚2‚3‚4 and Toni Cathomen1 Abstract Zinc-finger nucleases (ZFNs) are a powerful tool that can be used to edit the human genome ad libitum. The technology has experienced remarkable development in the last few years with regard to both the target site specificity and the engineering platforms used to generate zinc-finger proteins. As a result‚ two

Summary This experiment will measure the rate of oxidation of iodide ions by persulphate ions to derive the rate law for the reaction. Starch will be added to the reaction to facilitate the measure of time during the reaction. The reactant solutions will contain (NH4)2SO4 and KI‚ represented as: (NH4)2S2O8 + 2KI -> I2 + (NH4)2SO4 + K2SO4 This can be simplified to: S2O82- + 2I- -> I2 + 2SO42- These equations can only be carried out and be visible after the iodine has completely

Copper and Zinc Composition Percentages in Pennies Introduction. The United States Mint sends copper and zinc to a fabricator‚ which creates coin-sized discs called planchets. The planchets undergo the coining press at the Mint where they are stamped as genuine United States legal tender coins. The purpose of this experiment is to determine the accuracy of the copper and zinc composition percentages in a random sampling of pennies. The penny was dissolved to make aqueous copper ions and four copper
