Answer the following pre-lab questions in your lab notebook. Show all calculations and pay attention to significant figures. 1. 50.0 g of an unknown metal was heated to 95.0 °C and added to 45.0 g of water at 25.0 °C in a calorimeter. Once the system reached equilibrium the final temperature was 28.5 °C. Calculate the specific heat capacity of the metal with correct units. 2. 60.0 g of nickel heated to 100.0 °C was added to 55.0 g of water at 25.0 °C inside a calorimeter and the system was allowed to reach equilibrium. What would be the final temperature of the metal and water? (specific heat of Ni = 0.44 J/g °C) 3. One challenge during calorimetry is to minimize the heat lost to the environment during the experiment. Suggest how you would minimize the heat loss during the experiment (read the steps of the experiment before you answer the question)
