Be sure to answer all parts. Electric generating plants transport large amounts of hot water through metal pipes, and oxygen dissolved in the water can cause a major corrosion problem. Hydrazine (N2H4) added to the water avoids the problem by reacting with the oxygen:N2H4(aq) + O2(g) → N2(g) + 2 H2O(l)About 4 × 107 kg of hydrazine is produced every year by reacting ammonia with sodium hypochlorite in the Raschig process:2 NH3(aq) + NaOCl(aq) → N2H4(aq) + NaCl(aq) + H2O(l) ΔH o = −151 kJ(a) If ΔH o f of NaOCl(aq) = −346 kJ/mol, find ΔH o f of N2H4(aq). kJ(b) What is the heat released when aqueous N2H4 is added to 4.00 × 103 L of plant water that is 2.50 × 10−4M O2? Enter your answer in scientific notation. × 10 kJ heat released.
