HUU 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 (N2H) added to the water avoids the problem by reacting with the oxygen: N2H4(aq) + 026) ► N2()+2 H20(1) About 4 x 10 kg of hydrazine is produced every year by reaquing ammonia with sodium hypochlorite in the Raschig process: 2 NH3(aq) + NaOCl(aq) → N2H4(aq) + NaCl(aq)...
