When 1.540 g of liquid hexane (c6h14) undergoes combustion in a bomb calorimeter, the temperature rises from 25.29 ∘c to 38.17 ∘c. find δerxn for the reaction in kj/mol hexane. the heat capacity of the bomb calorimeter, determined in a separate experiment, is 5.75 kj/∘c. the combustion of toluene has a δerxn of –3.91×103 kj/mol. when 1.55 g of toluene (c7h8) undergoes combustion in a bomb calorimeter, the temperature rises from 23.12∘c to 37.57∘c. find the heat capacity of the bomb calorimeter.
