Here's how each conversion is carried out: a) Fe^2+_(aq) Fe^3+_(aq) This is an oxidation reaction. Step 1: Add an oxidizing agent such as acidified potassium permanganate (KMnO_4) or hydrogen peroxide (H_2O_2). Example reaction with hydrogen peroxide: 2Fe^2+(aq) + H_2O_2(aq) + 2H^+(aq) 2Fe^3+(aq) + 2H_2O(l) b) I^-_(aq) I_2(s) This is an oxidation reaction. Step 1: Add an oxidizing agent such as chlorine water (Cl_2(aq)) or hydrogen peroxide (H_2O_2). Example reaction with chlorine water: 2I^-(aq) + Cl_2(aq) I_2(s) + 2Cl^-(aq) c) C_2H_4 C_2H_6 This is a hydrogenation (addition) reaction. Step 1: React ethene (C_2H_4) with hydrogen gas (H_2). Step 2: Heat the mixture in the presence of a nickel catalyst (e.g., at 150-200°C). C_2H_4(g) + H_2(g) Ni catalyst, heat C_2H_6(g) d) C_2H_5OH C_2H_6 This conversion involves two steps: Step 1: Dehydration of ethanol to ethene. • Heat ethanol (C_2H_5OH) with concentrated sulfuric acid (H_2SO_4) at 170°C. C_2H_5OH(l) conc. H_2SO_4, 170^ C_2H_4(g) + H_2O(l) Step 2: Hydrogenation of ethene to ethane. • React the ethene (C_2H_4) produced with hydrogen gas (H_2). • Heat the mixture in the presence of a nickel catalyst (e.g., at 150-200°C). C_2H_4(g) + H_2(g) Ni catalyst, heat C_2H_6(g)
