(b) Heat is generated by the core of a nuclear reactor, this heat is removed by pumping cooling water through the core at a rate of 45 x 106 kg/h to generate steam. Cooling water, initially at 30 °C is continuously pumped through the reactor so that the outlet temperature is 748 °C and the core temperature remains constant. Calculate the rate of heat generated by the core of a nuclear reactor (in joules per second). (The specific heat capacity of ice 2100 Jkg 'K1; water = 4190 Jkg K; steam 2010 Jkg K. The latent heat of fusion of water is 334 kJ kg: latent heat of vaporisation of water 2264 kJ kg)
Last year a 20 GJ/hr boiler consumed 10,000 GJ of natural gas at $10/GJ. The boiler operates at 9% O2 and 350oC stack temperature rise (STR). What is the savings for correcting that to 4% O2?
Sucrose, C12 Hzm011, is common table sugar. The enthalpy change at 25°C and 1 atm for the complete burning of 3 mol of sucrose in oxygen to give CO:(9) and H3O(1) is - 1.692 x 10' kJ.

If the battery is defined as the system,what is the sign on w in part (b)?▲ Figure 5.10 Internal energy is a statefunction, but heat and work are not. (a) Abattery shorted out by a wire loses energy tothe surroundings only as heat; no work isperformed. (b) A battery discharged througha motor loses energy as work (to make thefan turn) and also loses some energy as heat.The value of ΔE is the same for bothprocesses even though the values of q and win (a) are different from those in (b).
A chemical manufacturer produces ethylene oxide by burning ethylene gas with air in the presence of catalyst. If the conditions are carefully controlled, a substantial fraction of ethylene remains unconverted and some is completely oxidized to form carbon dioxide and water. Formation of carbon monoxide is negligible. After the gases leaving the absorber is as follows: 9.6%CO2, 3.0%O2 and 6.4% ethylene. Of the ethylene entering the reactor, what percentage is converted to ethylene oxide?
Esc ||| = OTHERMOCHEMISTRY A student runs two experiments with a constant-volume "bomb" calorimeter containing 1200. g of water (see sketch at right). Calculating heat of reaction from bomb calorimetry data First, a 5.000 g tablet of benzoic acid (C6H,CO₂H) is put into the "bomb" and burned completely in an excess of oxygen. (Benzoic acid is known to have a heat of combustion of 26.454 kJ/g.) The temperature of the water is observed to rise from 16.00 °C to 38.96 °C over a time of 9.2 minutes. 2 4. Next, 5.730 g of acetaldehyde (C₂H₂O) are put into the "bomb" and similarly completely burned in an excess of oxygen.
