Given the following data: Fe2O3(s) + 3CO(g) → 2Fe(s) + 3CO2(g) ΔΗ -23 kJ 3FE2O3(s) + CO(g) → 2FE3O4(s) + CO2(g) AH=-39 kJ FezO4(s) + CO(g) → 3F€O(s) + CO2(g) AH = 18 kJ calculate AH value for the reaction FeO(s) + CO(g) → Fe(s) + CO2(g) ΔΗ kJ

Use the enthalpy for the combustion of propane (C3H8) to compare the energy from this common fuel to the ammonium nitrate. Calculate the mass in grams of propane that would be needed to release the same amount of energy solved for ammonium nitrate (10620877061.4693 kJ). The Enthalpy of combustion, ΔH = −2220.0 kJ/mol) please help me understand how to solve this quesiton. The answer is 0 g but i dont understand how or why.

Given these reactions, where X represents a generic metal or metalloid 1) H, (g) + 0,(g) H,O(g) ΔΗ = -241.8 kJ 2) X(s) + 2 Cl, (g) → XCl,(s) ΔΗ = +288.1 kJ 3) H,(g) + ¿Cl,(g) → HCI(g) ΔΗ -92.3 kJ 4) X(s) + O,(g) → XO,(s) AH4 = -529.5 kJ 5) Н, О(g) — н,О() H,O(1) AH5 = -44.0 kJ what is the enthalpy, AH, for this reaction? XCI, (8) + 2 H,О0() — ХО,(s)+4 HC(g) 141.62 ΔΗ kJ %3D Incorrect

Given these reactions, 1 X(s) + 0,(g) → XO(s) + CO,(g) XO(s) AH = -653.9 kJ/mol XCO,(s) AH = +444.5 kJ/mol what is AH for this reaction? 1 X(s) +0,(g) + CO,(g) XCO,(s) 2 -825.4 AH = kJ/mol Incorrect
