Copper Cycle Lab Chemistry 405 section 5 Kyle Reed September 28, 2006 Abstract: The purpose of this lab was to show that after putting copper through a series of chemical reactions, it is possible to re-obtain the copper at the end in a salt-like form. Introduction: The main goal of this lab was to put Copper through various forms of chemical reactions and observe what happens. We used the experiment to help us visually experience the law of conservation of mass. This is because we started with a specific amount of copper, put it through various tests in which it was no longer visible, then ended up with all of the copper in the end. The chemical reactions we put copper through were metathesis, decomposition, displacement, and oxidation-reduction. At the end of all the reactions we came back with a 112% yield which will be explained more in the results section. Discussion: The procedure gave us the results that we were looking for because even though copper wasn’t visible during the entire process, it was obviously there because when we added the sulfate and zinc then removed

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
