6. In a gas expansion 87 J of heat is released to the surroundings and the energy of the system decreases by 128 J. Calculate the work done. Consider the reaction: H2(g) + C12 (g) â 2HCl (g) Determine the amount of heat (in kJ) if 25.00 g of HCl are produced in the reaction. 7. H =-184.6 kJ/mol 8. Calculate the amount of heat produced (in kJ) by 325 g of mercury when it cools from 97.0 °C to 13.5 Given the thermochemical data: A + B â 2C 9. ÎH 1 = 600 kJ/mol Determine the enthalpy change for each of the following: 4E â 4C + 2D 10. Calculate the heat of reaction for the reaction below using the standard enthalpies of formation provided: 2C2H2(g) + 502(g) â 2CO2(g) + 2H20(1)
