if a balloon is inflated from 3.49 Liters to 5.54 Liters against an external pressure of 885.6 mmHg, how much work is done in joules?
joules:

4. When 1.806 grams of glucose (C6H12O6) is burned in a bomb calorimeter, the temperature rises from 21.236 degree Celsius to 25.211 degree Celsius. If the Ccal = 4.45 kJ/oC, find the delta H for the burning of 1 mole of glucose.
kJ/mole:

5. Calcium reacts with water to produce calcium hydroxide and hydrogen gas. If a 3.721 gram piece of calcium is place in 205 grams of 21.92 degree Celsius water and reacts the temperature rises to 35.9133 degree Celsius. Determine the Enthalpy change for the reaction of calcium and water. the specific heat of the solution is 4.05 J/oC g
kJ/mole:

6. List the four way delta H can be calculated.

7. What does the small "o" superscript on the delta H tell you ?
