5. A student is trying to identify a metal unknown. The student performs a calorimetry experiment similar to this week’s lab. The metal was heated to 115.0°C and placed in a calorimeter where it cooled to 32.6°C. The amount of heat released by 25.0g of the metal was 63.5 cal Calculate the specific heat of the metal and determine its identity by looking at the specific heat values in page 239 of your textbook. (Keep track of units!).
