Please help me with my he. I can't seem to solve this problem. I hope you can help me This is a guide to answer the activity. HESS LAW (Law of Heat Summation) “The enthalpy change of the overall process is the sum of the enthalpy changes of the individual component steps.” - It is the standard enthalpy of Reaction, ΔHᵒ. - It can be illustrated in the following example Consider the following reactions: (a) Fe(s) + O2(g) à FeO(s)ΔHᵒ = -272 kJ (b) 2 Fe(s) + O2 (g) à Fe2O3(s)ΔHᵒ = -82.5 kJ 1. Make sure to write the balance equation. 2. The final equation requires 2 moles of FeO which means we will multiply equation (a) and its enthalpy change by 2. 3. Reverse equation (a), which means, the product goes to the reactant side, (2) (FeO(s) à Fe(s) + O2(g))ΔHᵒ = (-272 kJ)(2) = 544 kJ 2 FeO(s) à 2 Fe(s) + O2(g))ΔHᵒ = -825.5 kJ 4. Combine the final equation (a) and the initial equation (b). And then cancel the same components with same number of particles. In this…
