The following thermochemical equation is for the reaction of hydrogen sulfide(g) with water(1) to form hydrogen(g) and sulfur dioxide(g). H2S(g) + 2H20(g)- →3H2(g) + SO2(g) AH = 207 kJ When 11.6 grams of hydrogen sulfide(g) react with excess water(1), kJ of energy are Hint: An amount of energy is expressed as a positive number. The sign of AH in the thermochemical equation indicates whether the energy is absorbed or evolved.
