Be sure to answer all parts. Deterioration of buildings, bridges, and other structures through the rusting of iron costs millions of dollars every day. Although the actual process also requires water, a simplified equation (with rust shown as Fe₂O3) is: 4 Fe(s) + 3 O₂(g) → 2 Fe₂O3(s) ΔHxn=-1.65 × 10³ kJ (a) What is the AHrn when 0.250 kg of iron rusts? __x 10__kJ __x__ 10__g Fe₂O3 (b) How much rust forms when 8.60 × 10³ kJ of heat is released?
