WebThe specific heat is a property of the substance being heated or cooled. For example, the specific heat of water is 4.18 J/(g · °C) meaning that 4.18 joules of heat energy are required to raise the temperature of 1 gram of water by 1.0°C. Not all processes that involve a change in enthalpy are accompanied by a change in temperature. WebThe accepted value for the enthalpy of neutralization of HCl is -57.2 kJ/mol. Calculate the % error in your determination. % 8. Suggest two (2) possible sources of error that would explain why the experimental value differs from the accepted value.
