QUESTION 30 YOU MUST SUBMIT WORK FOR THIS PROBLEM INTO A SEPARATE ASSIGNMENT. Consider the following reaction: Fe20(s) + CO(s) 2Fe(s) + CO2(g) AH°rxn = -24.8 kJ Molar masses (g/mole): Fe20(s) = 159.7; Fe(s) = 55.85; CO(g) = 28.01; CO2(g) = 44.01 %3D How much heat (in kļ) is absorbed in a reaction in which 123.4 grams of Fe(s) is reacted under these o The heat released in the reaction is kJ (pay attention to the significant figures)
