In an experiment to estimate the enthalpy change of a reaction, a student makes two aqueous solutions, each containing one of the reactants. The student combines the solutions, both originally at the same temperature, in a calorimeter and records the final temperature of the mixture. In addition to the masses of the solutions and the temperature change of the mixture, which of the following pieces of information does the student need to calculate the enthalpy change of the reaction? The density of the reaction mixture

Answer A: The density of the reaction mixture

A

The specific heat capacity of the reaction mixture

Answer B: The specific heat capacity of the reaction mixture

B

The boiling point of the reaction mixture

Answer C: The boiling point of the reaction mixture

C

D: The heat of fusion of the reaction mixture
