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 5.00 × 103 L of plant water that is 2.50 × 10−4M O2? Enter your answer in scientific notation. × 10 kJ heat released

In large buildings, hot water in a water tank is circulated through a loop so that the user doesn’t have to wait for all the water in long piping to drain before hot water starts coming out. A certain recirculating loop involves 300-foot-long, 1-inch--diameter PEX pipes with six 90° threaded smooth bends and two fully open gate valves. The PEX piping is considered to be smooth (roughness is 0). If the average flow velocity through the loop is 5 ft/s,...

The quantity of dissolved oxygen is a measure of water pollution in lakes, rivers, and streams. Water samples were taken at four different locations in a river in an effort to determine if water pollution varied from location to location. Location I was 500 meters above an industrial plant water discharge point and near the shore. Location II was 200 meters above the discharge point and in midstream. Location III was 50 meters downstream from the discharge point and near...

The Winkler method for dissolved oxygen in water is based on the rapid oxidation of solid Mn(OH)2 to Mn(OH)3 in alkaline medium. When acidified, the Mn (III) readily releases iodine from iodide. A 240.-mL water sample, in a stoppered vessel, was treated with 1.10 mL of a concentrated solution of NaI and NaOH and 1.10 mL of a manganese(II) solution. Oxidation of the Mn(OH)2 was complete in about 1 min. The precipitates were then dissolved by addition of 2.20 mL...
