Question
The following thermochemical equation is for the reaction of carbon dioxide(g) with hydrogen (g) to form acetylene(g) (C₂H₂) and water(g). 2CO₂(g) + 5H₂(g)→→→→→→ C₂H₂(g) + 4H₂O(g) ΔΗ = 46.5 kJ When 10.9 grams of carbon dioxide (g) react with excess hydrogen (g), 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.
