A1.00 g sample of n-hexane (c6h14) undergoes complete combustion with excess o2 in a bomb calorimeter. the temperature of the 1502 g of water surrounding the bomb rises from 22.64°c to 29.30°c. the heat capacity of the hardware component of the calorimeter (everything that is not water) is 4042 j/°c. what is δu for the combustion of n-c6h14? one mole of n-c6h14 is 86.1 g. the specific heat of water is 4.184 j/g·°c.
