say that I learned a lot from a chemistry class‚ and it will benefit me later in life. In this class‚ we learned a lot of tricks‚ but three of them were more interesting and important to me‚ dry ice and hot water‚ revealing fingerprints‚ and shiny pennies. The dry-ice demonstration was the best one that I’ve experimented‚ and I think it’s a great reaction to be used in multiple situations. First of all‚ dry ice is frozen carbon dioxide.(Pangler) Instead of melting‚ dry ice turns directly into carbon

How does acid clean copper- “The oxygen in the air and the copper in the pennies form an oxide that coats the pennies and makes them look dirty. The acids break the copper oxide free from the penny. As we have seen experimentally‚ acid alone does not clean as well as acid and salt.” Can acid kill you?-”The actual causes of death however are not always from the

My four liquids will be vinegar‚ beach‚ lemon water and salt water. To get started‚ the metal contents should be established. Today’s pennies are mostly made of zinc with a thin layer of copper overcoating. A nail is a form of carbon steel or black iron. Paper clips are made from a low grade

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

After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating was used in a particular penny. Not knowing the about information‚ my original hypothesis was that the penny would contain

above‚ the mass of 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

DETERMINATION OF % COMPOSITION OF PENNIES USING REDOX AND DOUBLE DISPLACEMENT (PRECIPITATION) REACTIONS Pre- Lab 8 Objective: The purpose of this experiment is to determine the percent composition of pennies using oxidation-reduction and double displacement reactions as well as titration techniques. We will take a post 1982 penny and place in a strong acid dissolving the zinc core and leaving behind the copper coating. We will figure out the percent composition from the mass of copper and zinc using titration
