A sample of gas in a cylinder is provided with 6.204E2 kJ of heat. This causes a piston to then compress the gas by doing 4.357E2 kJ of work on the gas. What is the change in internal energy of the gas during this compression?
A 0.1375g sample of solid Mg is burned in a constant volume bomb calorimeter that has a heat capacity of 3024 J/0C. The temperature increases by 1.1260C. Calculate the heat given off by the burning Mg in kJ/g Mg and kJ/mole Mg
4 Having just invented a new type of calorimeter, Dr. Campbell needs to determine the heat capacity of the calorimeter. She carries out the following experiment to do this: She puts 20.0 grams of water in her empty calorimeter and it is allowed to stabilize at a temperature of 25.0ºC. She then adds 32.035 grams of water at a temperature of 83.2ºC to the calorimeter. After a few minutes the final temperature of the calorimeter stabilizes at 41.6ºC. Based on this experiment, what is the heat capacity of her calorimeter assuming units of J/ºC? Enter your answer with at least 3 sig figs.
In this experiment you will place a sample of your salt in water in a constant pressure calorimeter. You will determine the enthalpy change for the dissociation of your salt, Delta Hdiss.

a You want to determine the value for the enthalpy of formation of CaSO4(s). Ca(s) + S(s) + 2 O₂ (g) → CaSO4(s) This reaction cannot be done directly. You know, however, that both calcium and sulfur react with oxygen to produce oxides in reactions that can be studied calorimetrically. You also know that the basic oxide CaO reacts with the acidic oxide SO3 (g) to produce CaSO4(s) with A₁ H° = -402.7 kJ. Outline a method for determining A₁H˚ for CaSO4(s), and identify the information that must be collected by experiment. Using enthalpy of formation data, confirm that AƒH° for CaSO4(s) = −1433.5 kJ/mol. What compound is formed when Ca and O2 react?
