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 Fe,03) is: 4 Fe(s) +3 O2(g) 2 Fe,O3(s) AHn =-1.65 x 10° kJ (a) What is the AHn when 0.250 kg of iron rusts? x 10 kJ (b) How much rust forms when 7.70 x 10° kJ of heat is released? 1x10 g Fe,O3
