Questions come from the Bluebook question bank. Made by Iskaa303 (Iskander Madikhan).
Microbial fuel cells (MFCs) capitalize on the ability of some species of bacteria to oxidize organic matter and transfer electrons extracellularly. The bacteria form a dense biofilm on the surface of an electron-collecting anode, but moving the electrons from the bacterial cytoplasm to an external electrode requires that the electrons pass through a series of inefficient oxidation-reduction (redox) reactions. Accordingly, MFC power output rarely exceeds a density of 0.30 milliwatts per square centimeter (mW/cm2mW slash cm squared). In an experiment, researchers added silver nanoparticles to carbon paper covering the anode in an MFC. The resulting power density was 0.66 mW/cm2mW slash cm squared. Since metals such as silver exhibit high electrical conductivity, the researchers hypothesized that ______blank
