Calculate the ΔH for the following reaction: 3 Fe + 4 H2O → Fe3O4 + 4 H2
Given the following information:
FeO + H2 → Fe + H2O ΔH = +25 kJ
3 FeO + ½ O2 → Fe3O4 ΔH = -318 kJ
H2 + ½ O2 → H2O ΔH = -242 kJ

Nitrogen dioxide reacts with water to form nitric acid and nitrogen monoxide according to the equation: 3no2(g)+h2o(l)→2hno3(l)+no(g) part a suppose that 4.2 mol no2 and 0.50 mol h2o combine and react completely. which reactant is in excess? express your answer as a chemical formula. nothing
