Deterioration of buildings, bridges as well as other structures through the rusting of iron costs millions of dollars every day. Although the actual process as well requires water, a simplified equation with rust shown as Fe2O3 is given below. 4Fe(s)+3O2(g)-->2Fe2O3(s) Delta Hrxn= -1.65x103KJ
(b) Explain how much rust forms when 3.83 x 10^3 kJ of heat is released?
