What is the standard enthalpy change for the reaction CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l)?

• A. ΔH⁰ = [Hm(CH₄) + 2Hm(O₂)] – [Hm(CO₂) + 2Hm(H₂O)]
• B. ΔH⁰ = [Hm(CO₂) × 2Hm(H₂O)] – [Hm(CH₄) × 2Hm(O₂)]
• C. ΔH⁰ = [Hm(CO₂) + Hm(H₂O)] – [Hm(CH₄) + Hm(O₂)]
• D. ΔH⁰ = [Hm(CO₂) + 2Hm(H₂O)] – [Hm(CH₄) + 2Hm(O₂)]
