Question
**Classify each half-reaction as a reduction or an oxidation.** 1. Cr\(_2\)O\(_7^{2-}\) (aq) + 14 H\(^+\) (aq) + 6 e\(^-\) → 2 Cr\(^{3+}\) (aq) + 7 H\(_2\)O(l) 2. Fe\(^{3+}\) (aq) + 3 e\(^-\) → Fe(s) 3. Au(s) + 2 CN\(^-\) (aq) → Au(CN)\(_2^-\) (aq) + e\(^-\) 4. HgO(s) + H\(_2\)O(l) + 2 e\(^-\) → Hg(l) + 2 OH\(^-\) (aq) 5. 2 Cl\(^-\) (aq) → Cl\(_2\) (g) + 2 e\(^-\) **Answer Bank:** - oxidation - reduction **Diagram Description:** - Each half-reaction is paired with an empty box on the left side for indicating whether the reaction is an "oxidation" or "reduction." - The answer bank at the bottom contains the words "oxidation" and "reduction" to fill in the boxes appropriately.
