the enthalpy of combustion of CH4(g) to make H2O(l) and CO2(g) is -2340 kJ mol-1. The enthalpy of combustion of CH2(g) to make H2O(l) and CO2(g) is -2760 kJ mol-1. The enthalpy of formation of H2O(l) is -286 kJ mol-1. All the data are for 298 K. The heat capacities for O2(g), CHA(8), CH3(g), H2O(l) and CO2(8) are 29, 61, 71, 75 and 37 JK"mor", respectively. Deduce a) 4U298 for the combustion of C4H8(g). 5) AH for the combustion of...
If H2 + 1/2 O2 ----> H2O has an enthalpy of -286 KJ, the enthalpy change for making 573 grams of H2 is ______ (a number)
1) The enthalpy of formation for H2O(l) is given by H2(g) + 1/2 O2(g) → H2O(l). Add this reaction to H2O(l) + 1/2 O2(g) → H2O2(aq). This is the reverse of the decomposition reaction from this experiment. Show the sum of the above two reactions is the enthalpy of formation of H2O2(aq) 2) Calculate the literature value for the enthalpy of decomposition of H2O2(aq) from the enthalpies of formation of H2O2(aq), H2O(l) and O2(g) found in your textbook or any...
