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) ΔrH° = −151 kJ
(a) If ΔfH° of NaOCl(aq) = −346 kJ/mol, find ΔfH° of N2H4(aq) given that
ΔfH° [NH3(aq)] = −80.83 kJ/mol,
ΔfH° [NaOCl(aq)] = −346 kJ/mol,
ΔfH° [Na+(aq)] = −239.66 kJ/mol,
ΔfH° [Cl−(aq)] = −167.46 kJ/mol and
ΔfH° [H2O(l)]= −285.840 kJ/mol.
What is the heat released when aqueous N2H4 is added to 7.00 × 103 L of plant water that is 2.50 ×10−4 mol/L O2? Enter your answer in scientific notation.
