Homework Help: Chemistry

Posted by Tabetha on Tuesday, May 19, 2009 at 7:04pm.

how many moles of O2 would be needed to produce 1120.5 kJ of heat from the reaction:

3Fe + 2O2 yields Fe3O4+ 1120.5 kJ I got 627771.33 which I thought seemed a bit too high. My proportion was 1120.5=2 O2/1120.5.

Thanks again.
