To determine which of the given reactions is a redox reaction, we need to analyze the oxidation states of the elements involved in each reaction and check for changes. A redox reaction involves both oxidation (increase in oxidation state) and reduction (decrease in oxidation state). ### Step-by-Step Solution: 1. **Identify the Reactions**: We have four reactions to analyze. Let's denote them as Reaction 1, Reaction 2, Reaction 3, and Reaction 4. 2. **Analyze Reaction 1**: ...
