Calculate the standard enthalpy change for the phase transition reaction, where 1 mole of solid water (ice) is transformed into 1 mole of liquid water at a constant pressure of 1 atm and a temperature of 298 K. Given the specific heat capacity of ice is 2.108 J g^-1 K^-1 and the specific heat capacity of water is 4.184 J g^-1 K^-1. The molar enthalpy of fusion of water is 6.01 kJ/mol.

A chemistry student wants to determine the specific heat capacity of an unknown metal. The student performs a calorimetry experiment and records the following data: - 50 mL of water at 25°C was added to a calorimeter. - The initial temperature of the metal was 100°C. - The final temperature of the metal and water mixture was 30°C. - The mass of the metal was 100 grams.What is the specific heat capacity of the metal?
