A fuel cell is аn electrоchemicаl device, much like а battery. Hоwever, a battery is self cоntained. In other words, it contains all the reactants needed to produce electricity. In contrast, a fuel cell requires a constant supply of one or more reactants. A methanol fuel cell uses methanol as the main fuel source, and oxygen flows in from the outside air. While some race cars used to burn methanol in an internal combustion engine, a fuel cell converts the stored energy in the methanol into an electrical current instead of a flame. CH3OH(l) + O2(g) → CO2(g) + H2O(l) Identify the oxidation number of the following elements: The carbon in CH3OH The oxygen in CH3OH The oxygen in O2 The carbon in CO2 The oxygen in CO2 The oxygen in H2O Based on your answers in part A, identify which substance in the reaction is oxidized and which is reduced. Balance this equation using whole numbers. Then identify the coefficients in front of each substance in the reaction. CH3OH = O2 = CO2 = H2O = Show your work. Note: Your answer(s) must be provided in this text box. If you are unable to show your work adequately using the Rich Text Editor, complete your work on scratch paper. Upload a photo of your work in the "Comments" of this exam immediately after you have completed and submitted the exam. You can access the "Comments" through the grade book. Answers on scratch paper alone will not be scored.
