What is enthalpy of combustion? A chemist uses a coffee-cup calorimeter to neutralize completely 75.0 mL of 6.67 mol/L HCl with 75 mL of NaOH. The temperature change is 39.6 degrees Celsius. Calculate the heat of neutralization, in kJ/mol of HCl. a. + 49.8 kJ/mol b. -49.8 kJ/mol ...
The enthalpy of sublimation is a measure of how much energy in the form of heat is required to transition onemoleof a substance from a solid state to a gaseous state at standard temperature and pressures. Measured in kJ/mol, the enthalpy of sublimation can be calculated by adding the enthal...
Enthalpy is a measure of the total heat content of a system, reflecting energy changes in chemical reactions at constant pressure, whereas entropy quantifies the disorder or randomness in a system, crucial for determining spontaneity.
If we look at this from the perspective of a gas boiler, a quick exothermic reaction, combustion, occurs. The energy is then released into the surroundings. The change in enthalpy (ΔH) is negative because the energy is being lost by the system (the heater) and gained by the surroundings...
