Hgo → Hg + O2D. 2H90(s) → 2Hg + O2 (g)_11. Which of the following matches the given description?1mol of CSH12(1) reacts with 8mol of Oz(a) to produce 5mol of CO2(a), 6mol of H20(1)and releasing 3.523kJ is referred to as one mole of reaction.A. CSH12 + O2→ CO2+ H20 AH = 3,523kJB. CSH12 (1)+802 (g) →5CO2(g). 6H20(1) AH = 3,523KJC. CSH12 + O2» CO2. H20AH = 182kJAH = 182kJAH = - 3,523KJD. CSH12 (1)+802(g) →5CO2(g) +6H20(1) AH = -3,523kJ_12. Which of the following substances has the greatest entropy per mole?A. O2(g)B. N2(g)C. CO(g)D. CAH10(g)
