True/False

II. GENERAL INSTRUCTIONS Read and analyze carefully each problem. Show your complete solution. 1. Balance each redox reaction in basic medium. Don't forget to identify the oxidation half- reaction and reduction half-reaction. b. Te + NO Teo]¯ + N₂0₂ c. 105 + Re-Re0 + 10

Your friend Robin was absent the day balancing redox reactions was taught. She is trying to determine when you would use oxidation method vs. the half-reaction method. Explain when each method would be a good choice and why.

24. What will happen if a student measures the voltage of a voltaic cell where the student mixed the two half-cells together without separating them with a salt bridge?   The student will probably experience an electrical shock.   The reaction will happen much more rapidly so register a higher voltage.   No reaction will occur without a salt bridge.   No voltage will be recorded.
