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)H=46.5kJ/molrxn When 14.7 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 indicates whether the energy is absorbed or evolved. swer 6 more group attempts remaining
