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 Fe202) is: 4 Fe(s) + 3 02(g)→ 2 Fe,O3(s) AHxn =-1.65 x 103 kJ %3D (a) What is the AHxn when 0.250 kg of iron rusts? x 10 kJ (b) How much rust forms when 7.00 x 10' kJ of heat is released? x 10 g Fe,03

In the 1980s, there was an international agreement to de-stroy all stockpiles of mustard gas, ClCH₂CH₂SCH₂CH₂Cl.When this substance contacts the moisture in eyes, nasal pas-sages, and skin, the -OH groups of water replace the Cl atoms and create high local concentrations of hydrochloric acid, which cause severe blistering and tissue destruction. Write a balanced equation for this reaction, and calculate ΔH°ᵣₓₙ.
