Name Quiz 12 ENGSC 3313, Spring 2000 ~nswer any 4 Questions only, 1 point each 1 It is the reference by which everything else is compared. Cross country pipelines are more likely to corrode under riverbeds and under paved roads than elsewhere, if not properly protected. Reason why! 2 These would be oxygen deficient zone~, hence @Qili£ regions and anodes corrode. Oxygen partakes in cathodic reactions such as 02 + 2H20 + 4e- ~ 4(0H)" + - 02+4H +4e ~2H20 Thus high oxygen regions are cathodes 3 FIG. 14-2.6 Galvanic Microcells (AI-Si Alloy). Any two-phase alloy is more subject to corrosion than is a single-phase alloy. A two-phase alloy provides anodes and cathodes. (Courtesy of Aluminum Company of America.)

    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.
