Deterioration of buildings bridges as well as other, Ask an Expert

Academics

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?
