1. Find D E for an exothermic reaction in which 12 kJ of heat flows and where 3400 J of work is done on the system.
-8.6 kJ 8.6 kJ 15.4 kJ -15.4 kJ none of the above

2. The pathway is independent of:
work change in energy heat volume none of the above

3. The first law of thermodynamics states:
energy can neither be destroyed nor produced the energy of universe is constant the entropy of a perfect crystal is zero the entropy of the universe is increasing none of the above

4. When a wheel rolls on a surface, the energy transferred by the tires to the surface is called:
fictional heating potential energy kinetic energy carpet burn pathway

5. 500mL of solution A at 23.0C is mixed with 500mL of solution B in a bomb calorimeter. The final solution has a density of 2.0g/mL, final temperature of 26.3C, and a specific heat capacity of 5.12 J/C*g. What is the enthalpy change per mole of the final solution?
3.3 x 104 J 3.37 x 104 J 1.7 x 104 J 1.68 x 104 J 2.4 x 104 J
