Select all of the following that are true in regards to redox reactions. Question 6 options: Oxidation occurs at the cathode of a galvanic cell. An oxidizing agent is needed to convert CO into CO2. If a species is oxidized, it is formally losing electrons. Electron flow is always from the anode to the cathode in an electrochemical cell. If there are no changes in the oxidation state of the reactants or products of a particular reaction, that reaction is...
