Thinking and Inquiry1. A coffee cup calorimeter is filled with 25.0 mL of water at22.10 °C. A 50g piece of metal at 28.78 °C is carefully addedand the system closed. After 15 minutes the final temperature ofthe water in the calorimeter is 23.20 °C. The density of the liquidwater is 1.0 g/mL, and it's specific heat capacity is 4.18J/(g.oC). Determine the specific heat capacity of the metal.What is the metal?2. The molar enthalpy for the dissolution ammonium chlorine(NH4Cl) is +14.8 KJ/mol. What is the final temperatureobserved when 20g of ammonium chloride is added to 125mL ofwater that is 20°C?
