Use the References to access important values if needed for this question. The following thermochemical equation is for the reaction of carbon dioxide(g) with hydrogen (g) to form carbon monoxide(g) and water(g). CO₂(g) + H₂(g)→→→ CO(g) + H₂O(g) AH = 41.2 kJ When 10.2 grams of carbon dioxide(g) react with excess hydrogen (g), Submit Answer 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. kJ of energy are Retry Entire Group 9 more group attempts remaining
