Question 1

For an explosion in an open vessel, one would expect
◦ ΔH to be positive and ΔE to be less than ΔH.
◦ ΔH to be positive and ΔE to be greater than ΔH.
◦ ΔH to be negative and ΔE to be greater than ΔH.
◦ ΔH to be negative and ΔE to be less than ΔH.

Question 2

When 20.00 moles of H2(g) reacts with 10.00 mol of O2(g) to form 20.00 mol of H2O(l) at 25°C and a constant pressure of 1.00 atm. If 1366 kJ of heat are released during this reaction, and PΔV is equal to -74.00 kJ, then
◦ ΔH° = -1366 kJ and ΔE° = -1440 kJ.
◦ ΔH° = +1366 kJ and ΔE° = +1440 kJ.
◦ ΔH° = -1366 kJ and ΔE° = -1292 kJ.
◦ ΔH° = +1366 kJ and ΔE° = +1292 kJ.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
