Deterioration of buildings, bridges, and other structuresthrough the rusting of iron costs millions of dollars every day.Although the actual process also requires water, a simplifiedequation (with rust shown as Fe2O3) is 4Fe(s)+3O₂(g)→2Fe₂O₃(s) ΔHᵣₓₙ =-1.65X10^3kJ (a) How much heat is evolved when 0.250 kg of iron rusts?(b) How much rust forms when 4.85103kJ of heat is released?
