When H2S(g) reacts with H20() to form H2(g) and SO2(g), 295 kJ of energy are absorbed for each mole of H2S(g) that reacts. Write a balanced thermochemical equation for the reaction with an energy term in kJ as part of the equation. Note that the answer box for the energy term is case sensitive Use the SMALLEST INTEGER coefficients possible and put the energy term in the last box on the appropriate side of the equation. If a box is...
QUESTION 7 H2 and F2 react according to the following equation, forming HF. H2 + F2 --> 2HF (AH = -271 kJ/mol rxn) If H2(g) and F2(g) were reacted in a calorimeter, the reaction that occurred would be: O exothermic, and the water temperature in the calorimeter temperature would rise. O endothermic, and the water temperature in the calorimeter temperature would rise. endothermic, and the water temperature in the calorimeter temperature would fall. exothermic, and the water temperature in the...
