PLEASE HELP!!
From the following data, C (graphite) + O₂(g) → CO₂ (8) H₂(g) + O₂(g) → H₂0 (1) 2C₂H6(g) + 70₂(g) → 4CO₂(g) + 6H₂O (1) Calculate the enthalpy change for the reaction below: 2C (graphite) + 3H₂(g) → C₂H6 (8) Be sure your answer has the correct number of significant digits. kJ X 3 ΔΗ° ΔΗ° ΔΗ° -393.5 = -285.8 rxn =-3120.8 rxn rxn kJ mol kJ mol = kJ mol
