### Oxidation-Reduction Reaction Identification**Question 4: Which of the following equations represents an oxidation-reduction reaction?****Options:**a. \( \text{Ca(OH)}_2 \, (s) + \text{H}_2\text{SO}_4 \, (aq) \rightarrow 2\text{H}_2\text{O} \, (l) + \text{CaSO}_4 \, (s) \)b. \( \text{CaO} \, (s) + \text{H}_2\text{O} \, (l) \rightarrow \text{Ca(OH)}_2 \, (s) \)c. \( \text{Zn} \, (s) + \text{Cu(NO}_3)_2 \, (aq) \rightarrow \text{Zn(NO}_3)_2 \, (aq) + \text{Cu} \, (s) \)d. \( \text{AgNO}_3 \, (aq) + \text{NaCl} \, (aq) \rightarrow \text{AgCl} \, (s) + \text{NaNO}_3 \, (aq) \)**Explanation:**An oxidation-reduction (redox) reaction involves the transfer of electrons between two species. It consists of two half-reactions: oxidation (loss of electrons) and reduction (gain of electrons).**Detailed Analysis of Options:**- **Option a:** \( \text{Ca(OH)}_2 \, (s) + \text{H}_2\text{SO}_4 \, (aq) \rightarrow 2\text{H}_2\text{O} \, (l) + \text{CaSO}_4 \, (s) \) - This is an acid-base neutralization reaction and does not involve electron transfer.- **Option b:** \( \text{CaO} \, (s) + \text{H}_2\text{O} \, (l) \rightarrow \text{Ca(OH)}_2 \, (s) \) - This is a combination reaction, where compounds are combined without electron transfer.- **Option c:** \( \text{Zn} \, (s) + \text{Cu(NO}_3)_2 \, (aq
