NEET Chemistry Hess's Law MCQ Question

Using Hess's Law, calculate the standard enthalpy change for the reaction: C(graphite, s) + 2H2(g) → CH4(g), given the following reactions: 1) C(graphite, s) + O2(g) → CO2(g); ∆rH⁰ = -393.5 kJ mol⁻¹, 2) H2(g) + 1/2 O2(g) → H2O(l); ∆rH⁰ = -285.8 kJ mol⁻¹, 3) CH4(g) + 2O2(g) → CO2(g) + 2H2O(l); ∆rH⁰ = -890.3 kJ mol⁻¹.
