C4h10(g) + 13/2 o2(g) 4 co2(g) + 5 h2o(g) H = -1895 kj: -8960 kj, - 401 kj, -155 kj, -32. 7 kj, a bomb calorimeter has a heat capacity of 675 j/ c and contains 925 g of water. If the combustion of 0. 500 mole of a hydrocarbon increases the temperature of the calorimeter from 24. 26 c to 53. 88 c, determine the enthalpy change per mole of hydrocarbon. The specific heat of water = 4. 18 j g-1 c-1: -94. 78 kj, -134. 6 kj, -269. 3 kj, -802. 3 kj. H = -1118. 4 kj: determine the heat of reaction for the process. Fe2o3(s) + feo(s) fe3o4(s) using the information given below: 3fe(s) + 2o2(g) fe3o4(s: -1074. 0 kj, -22. 0 kj, 249. 8 kj, 1074. 0 kj, the standard enthalpies of formation for several substances are given below:
