**Question:**In which reaction does the oxidation number of oxygen increase?**Options:****A.** \( \text{MgO (s)} + \text{H}_2\text{O (l)} \rightarrow \text{Mg(OH)}_2 \text{ (s)} \)**B.** \( 2\text{SO}_2 \text{ (g)} + \text{O}_2 \text{ (g)} \rightarrow 2\text{SO}_3 \text{ (g)} \)**C.** \( 2\text{H}_2\text{O (l)} \rightarrow 2\text{H}_2 \text{ (g)} + \text{O}_2 \text{ (g)} \)**D.** \( \text{HCl (aq)} + \text{NaOH (aq)} \rightarrow \text{NaCl (aq)} + \text{H}_2\text{O (l)} \)**E.** \( \text{Ba(NO}_3\text{)}_2 \text{ (aq)} + \text{K}_2\text{SO}_4 \text{ (aq)} \rightarrow \text{BaSO}_4 \text{ (s)} + 2\text{KNO}_3 \text{ (aq)} \)**Explanation of Correct Option:**In this question, you need to determine which reaction involves an increase in the oxidation number of oxygen. Consider the following:- Option **A** involves the reaction of magnesium oxide with water, forming magnesium hydroxide. Here, the oxidation state of oxygen does not change. - Option **B** involves the reaction of sulfur dioxide with oxygen to form sulfur trioxide. The oxidation number of oxygen remains unchanged.- Option **C** involves the decomposition of water into hydrogen and oxygen gas. In this reaction, the oxygen molecules are formed from water, where each oxygen is initially assigned an oxidation state of -2. In \( \text{O}_2 \), the oxidation state of oxygen is 0, indicating an increase.- Option **D** describes a neutralization reaction between hydrochloric acid and sodium hydroxide, which does not change the oxidation state of oxygen.- Option **E** describes a double displacement reaction between barium nitrate and potassium sulfate, which involves no change in the oxidation states of any
