Lab #2 Determination of Density Britney Williams Chemistry 121 Dr. Yu 1/29/13 Purpose: To determine the densities of aluminum and zinc cylinders Density is the relationship between the mass of an object and its volume. Sometimes density can be easy to sense. If two objects have exactly the same shape and size‚ the denser one may feel heavier. If their densities are close together‚ it can be hard to tell the difference. It gets really tough if you are dealing with materials that have very different

cathode or positive terminal (such as copper) and an anode or negative terminal (such as zinc). These are placed in an electrically conductive solution that allows ions to travel freely between the two metals. The solution is typically an acid. Car batteries use sulfuric acid‚ but potatoes contain phosphoric acid‚ which also works. The acid steadily eats away at the zinc‚ a chemical reaction that releases spare zinc electrons. These electrons then join with spare hydrogen ions in the acid to create hydrogen

that come about by using oxidation reduction and recording the observations‚ these tests will help determine the specific qualities each solution has. Hypothesis I theorize that nothing will happen with Magnesium because it is such a soft metal. Zinc should turn a greener color‚ because that’s what happens to a lot of statues and sculptures. I theorize that iron will tarnish badly because in air it can get tarnished so oxidation must do something as well. Materials 1 Paper towels 1 Well-Plate

Zinc (metal) and sulfur (non metal) were analyzed through various tests were conducted for both elements. For the conductivity test‚ it was discovered that zinc was a good conductor of electricity while sulfur was a poor conductor. For the lustre test‚ zinc possessed metallic lustre and sulfur had a dull appearance. For the malleability test‚ zinc was malleable/flexible and sulfur was brittle. For the melting point test‚ zinc had a higher melting point compared

Title: Calculating the Atomic Mass of “Pennium” Purpose: The purpose of this lab is to calculate the atomic mass of “pennium” 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

disease. This disease is a result of mutations of the SLC39A4 gene that codes for transport protein ZIP4 which is responsible for the uptake of zinc in the intestine cells of infants. This disease will often show up when the infants are weaned off their mother’s breast‚ it is believed that somehow breast milk inhibits this disease because it contains zinc‚ but once the infant is weaned and starts feeding on
