Problem 43E

Energy Changes in Nuclear Reactions (Section)

The thermite reaction, Fe2O3(s) + 2 Al(s) →2 Fe(s) + Al2O3(s), ΔH° = -851.5 kJ>mol, is one of the most exothermic reactions known. Because the heat released is sufficient to melt the iron product, the reaction is used to weld metal under the ocean. How much heat is released per mole of Fe2O3 produced? How does this amount of thermal energy compare with the energy released when 2 mol of protons and 2 mol of neutrons combine to form 1 mol of alpha particles?

Step-by-Step Solution:
Step 1 of 3

Nuclear Power: Module 2 Fukushima Nuclear power plant disaster  Earthquakes are common in Japan because they sit on the pacific rim of fire  Japan relies on nuclear power because they do not have as much access to fossil fuels and wants to be energy independent  Most located near cost, where they have access to cooling power  After earthquake many of the power plants automatically shut down, however some were damage from the earthquake on the west cost and suffered through the tsunami o Fukushima plant took direct hit - electrical power lost (lost safety features) o Seawalls weren't big enough o Not enough back up safety features  Safety cooling water should have been part of it 
