WRITTEN PROBLEMUplоаd yоur wоrk to the аssignment on Cаnvas after you finish the exam AND type out your answer here. The answer typed here must match what is written on your uploaded work, or you will be given no credit for this question.Use Hess's law and the reactions below to calculate ΔH for the target reaction C(s) + 2 H₂(g) → CH₄(g).Reaction 1: C(s) + O₂(g) → CO₂(g), ΔH = −393.5 kJReaction 2: H₂(g) + ½ O₂(g) → H₂O(l), ΔH = −285.8 kJReaction 3: CH₄(g) + 2 O₂(g) → CO₂(g) + 2 H₂O(l), ΔH = −890.3 kJ.(a) Show how you reverse and/or multiply each reaction so they add to the target. Don't type out the answer to this question, only include it with your written work.(b) Calculate ΔH for the target reaction. Include the sign and units.
