Thermo Practice Problems #1 Clemens 1. A 0.922g sample of naphthalene (C 10 H 8 ) is burned in a calorimeter that has a heat capacity of 0.944 kJ/K. The temperature of the calorimeter rose from 15.73 o C to 19.75 o C. Calculate the heat of combustion for naphthalene in kJ/mol. 2. A 50.0g ice cube at 0 o C is added to a glass containing 425g of water at 45 o C. What is the final temperature once all the ice has melted? The heat of fusion for water is 6.02kJ/mol.

Unformatted text preview: 3. How much heat is involved in condensing 65mL of ethanol (CH 3 CH 2 OH, d = 1.59g/mL) if the heat of vaporization for ethanol is 35.6kJ/ml? 4. 25.0mL of 1.0M H 2 SO 4 is added to 50.0mL of 1.0M NaOH in a calorimeter at 25 o C and the temperature rose to 33.9 o C. Calculate the heat released in this reaction in kJ per mole of water produced. Assume that the density of the solution formed is 1.00g/mL with a specific heat of 4.18J/g o C....
