    Percent Composition of a Penny Background Information: Post-1983 pennies have a copper jacket and a zinc core. We hope to determine the percent composition of these two metals. This will be done by reacting the zinc with hydrochloric acid to form zinc ions in a single replacement reaction. The acid reacts with the zinc but not copper. The reaction of zinc metal with the hydrochloric acid (HCl) produces zinc chloride and hydrogen gas. Safety: Wear your safety goggles and apron If you spill Hydrochloric

    In the Penny Cleaning Lab‚ my hypothesis‚ which stated that the lemon juice would be the best at cleaning the penny since it is an acid and acids are particularly good at cleaning metallic substances‚ was indeed valid. First‚ we started out with 1mL solutions of all the substances in the test tray. We dipped the pH paper in each solution for about a second and recorded the pH level for each substance. Before starting‚ we noticed that all the pennies were in some shade of brown‚ which I predicted

    using pennies made before 1982 and pennies made 1982 or after. Hypothesis: The atomic mass of the pennium will be the average of the average masses of a pre-1982 penny and a post 1982 penny. Procedure: 1. Obtain a bag of pennies 2. Determine the total number of pennies in the bag. Record the value. 3. Sort the pennies by date into 2 piles. One pile should consist of pennies older than 1982‚ the other pile should include pennies that are 1982 or newer. 4. Count the number of pennies in each

    explore the cycle of copper through many chemical reactions. What we are going to do is take a piece of copper metal put it through a series of reactions that change it¡¦s state of matter and chemical formula‚ but in the end‚ we will return it to it¡¦s normal solid state. Determine the percentage yield (quantitative). Define what happen at level of electron for oxidation/reduction‚ double replacement‚ neutralization and decomposition. There are five reactions that the copper will go through. 1
