1 Cumulative Exam (Chemistry) Questions and Answers Already Passed In the context of a redox reaction, what does reduction mean? ✔✔The acquisition of electrons. The loss of electrons. The formation o f a new substance. The transfer of protons. How is the Au³⁺ ion characterized? ✔✔It acts as the oxidizing agent. It is the reducing agent. It is neutral. It is the substance being reduced. In a disproportionation reaction, what feature does the reacting substance possess? ✔✔It exhibits at least three distinct oxidation states. It maintains a single oxidation state. It remains unchanged. 2 It can only have two oxid ation states. Why is it necessary to determine oxidation states when using the half reaction method for balancing equations? ✔✔To pinpoint the half reactions within the equation. To calculate the total charge of the reaction. To id entify the overall reaction rate. To find the reactants and products. After determining the oxidation states of atoms, what is the next step in the half reaction method for balancing equations? ✔✔Identifying the half reactions. Balancing the overall equation. Calculating the total number of electrons transferred. Assigning oxidation numbers to each atom. What is a crucial step in the alternate method for balancing redox reactions? ✔✔Determining the half reactions of the chemical equations.
