Joseph Vasquez Design: The manipulated variable is the number of drops of catalase (1,2,3) we are exposing to the hydrogen peroxide (H2O2) which is at a concentration of 3%. The control for the experiment is the hydrogen peroxide (H2O2) being exposed to zero drops of catalase. Three constant factors of this experiment are 3 ml of hydrogen peroxide (H2O2) for each test tube,the same catalase, and 180 seconds of data collecting for each test. Data: Overall rate of pressure of oxygen (kPa) for every drop of catalase added to hydrogen peroxide (H2O2) Drops of catalase overall rate of pressure of oxygen (kPa) 0 0.002917 1 0.00825 2 0.022667 3 0.017278

"Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

    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.
