3. If the following redox reactions are found to occur spontaneously, identify the more active metal (might be fictional) in each reaction.

Identifying oxidising and reducing agents

3Zn + 2NO,+ 8H*→2NO + 3Zn2++ 4H,0 In the above reaction, the oxidation state of nitrogen changes from | to How many electrons are transferred in the reaction?

(A) if both sentences are true,(B) if both sentences are false,(C) if the first sentence is true but the second is false, and(D) if the first sentence is false but the second is true. 1. An acidic and a basic solution may be used to balance the redox reaction when the oxidation number method is employed.  The final step in balancing redox reactions using the oxidation number method is to balance by inspection. 2. In the oxidation number method of balancing redox reactions, there is a need to add water and hydroxide ions on both sides of the chemical reaction. The oxidation state of oxygen is always (-2) except for peroxides.  3. In the half-reaction method of balancing redox reactions, the reaction is divided into three half-reactions. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is an oxidizing agent. 4. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is a reducing agent.  In a redox reaction, the oxidation…
