4.746 g of of an unknown substance was burned in a bomb calorimeter. The calorimeter contained 986.2 g of liquid water and the bomb. Assume that the specific heat capacity of the liquid water is 4.184 J/(g ºC). The bomb (without the water) had a heat capacity of 790.2 J/ºC. How much heat was produced, if the bomb and the water went from 24.063 ºC to 28.719 ºC?

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
