Expiremental Variables - We will be able to identify the mass of a penny and how it can test the strength of a pasta noodle as a result of the downward pull of gravity on the penny. Test Variable: The type of noodle is what I’d be changing throughout the process Outcome Variable: I would be observing how many pennies each noodle could hold counting every

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

Hypothesis: I think that the surface tension of soapy water will be less than that of freshwater because H 2 0 has strong polar bonds‚ and when water is mixed with soap the polar bonds which help to bind the water together are weakened‚ thus lessening the surfacetension. Materials: pipette‚ liquid soap‚ water‚ beakers‚ penny‚ graduated cylinder
