A chemistry student is given the following thermochemical equations: Equation 1: H2 (g) + 1/2O2 (g) → H2O(l) ΔH1 = -285.8 kJ/mol Equation 2: C(s) + O2 (g) → CO2 (g) ΔH2 = -393.5 kJ/mol Equation 3: 2H2 (g) + O2 (g) → 2H2O(l) ΔH3 = -571.6 kJ/mol Using Hess's Law, calculate the enthalpy change for the following reaction: C(s) + 2H2 (g) → CH4 (g)
