Question

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?
