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) (a) What is the AHrxn when 0.250 kg of iron rusts? x 10 kJ x 10 (b) How much rust forms when 5.80 x 103 kJ of heat is released? AHxn-1.65 × 10³ kJ g Fe₂O3
