**Week 6 Assignment: Electrochemistry** **Problem 20.20 - Enhanced - with Feedback** **Part A** Indicate whether the following balanced equations involve oxidation-reduction. Check all that apply. 1. \(\text{2Fe}_3\text{O}_4(s) \rightarrow 6\text{FeO}(s) + \text{O}_2(g)\) 2. \(\text{2AgNO}_3(aq) + \text{CoCl}_2(aq) \rightarrow 2\text{AgCl}(s) + \text{Co(NO}_3\text{)}_2(aq)\) 3. \(\text{2H}_2\text{SO}_4(aq) + 2\text{NaBr}(s) \rightarrow \text{Br}_2(l) + \text{SO}_2(g) + \text{Na}_2\text{SO}_4(aq) + 2\text{H}_2\text{O}(l)\) **Submit** | **Previous Answers** | **Request Answer** **Feedback:** - **Incorrect; Try Again; 4 attempts remaining** One of the options you have identified does not exhibit oxidation and reduction because there is no change to the oxidation number of any of the atoms present among the reactants. With this in mind, reevaluate all the reactions and determine which exhibit both oxidation and reduction. **Part B** Complete previous part(s) **Part C** Complete previous part(s) **Provide Feedback**
