I need the precise energy release for a hydrocarbon combustion reaction. This is strictly a chemical-reaction analysis—no nuclear or electrochemical aspects are involved. Once I give you the molecular formula (e.g., CH₄, C₈H₁₈, or any other hydrocarbon), you will determine ΔH (kJ mol⁻¹) for the complete combustion in oxygen, referencing standard thermodynamic data at 25 °C. Please include: • the balanced equation, • the step-by-step enthalpy calculation (Hess’s Law, bond enthalpies, or tabulated ΔHf° values), • the final energy figure clearly stated per mole and, when requested, per kilogram, • citations for every data source you use (CRC Handbook, NIST webbook, etc.). A brief note on your calculation method or any software you plan to employ (Excel, Python, MATLAB) will help me reproduce the result later.
