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

Experimental Research of Wear On Filled PTFE Alloy Bearings ABSTRACT: Because of the lower coefficient of friction and good strength to weight ratio features polymer based composites are frequently used. In this work‚ experimental investigations were conducted on wear behavior of PTFE composite radial bearings filled with 15% glass fiber (GF15)‚ 40 % bronze (B40) and 35% carbon (C35) where bearing loads‚ sliding distances and wear were taken into account. For the fact that pivot pins have their

Percent Copper and Zinc in Pennies From Density Purpose: Practicing determine the density of the solution. Developing the method for determine the percent of density for the solution. Examining the linear relationship by learning to use the best-fit straight line. Using the linear relationship to determine the percent of density by the solution. Be familiar with recording data and observations. Methods & Material: Methods: Weight the mass for the different percent of zinc and copper mixtures

penny‚ copper‚ and zinc was needed in order to determine the percent composition of copper and zinc. The mass of penny was taken on the scale in the beginning of the procedure before anything was done to the penny‚ and it was 2.51 grams. After the reaction with the hydrochloric acid and drying the copper‚ the mass is 0.35 grams. To get the mass of zinc‚ the mass of the penny was subtracted by the mass of copper. The mass of zinc is 2.16 grams. The penny is 14% copper and 86% zinc by dividing the metal’s

when you put zinc in copper II sulfate? • What will happen when you put copper in copper II sulfate? Predictions: • We can predict that zinc will react with the aqueous solution of copper II sulfate and we will notice a reaction. We can also predict that the copper will not react with the solution of copper II sulfate and no reaction will be noticed. Hypothesis: • It is hypothesized the zinc metal will have a precipitation reaction with the solution of copper II sulfate‚ because zinc is more reactive
