Homework Help: Chemistry

Posted by Kaylene on Sunday, February 21, 2010 at 11:31pm.

Deterioration of buildings, bridges, and other structures through the rusting of iron costs millions of dollars everyday. Although the actual process also requires water, a simplified equation (with rust shown as iron(III) oxide (Fe2O3) is:

4Fe(s)+3O2(g) --> 2Fe2O3(s)

delta(h reaction =-1.65 x 10^3

How much heat is evolved when 0.250 kg of iron rusts?

How much rust forms when 2.00 x 10^3 kJ of heat is released?

I have tried everything and aris is not accepting it! Please tell me what I'm doing wrong!
