Question 1

When a substance dissolves in water, heat energy is released if:

◦ The lattice energy is positive.
◦ The hydration energy is positive.
◦ The hydration energy is more negative than the lattice energy is positive.
◦ The hydration energy is negative.
◦ None of these are correct.

Question 2

When solid Ca(CH3COO)2 is dissolved in a nearly saturated solution of Ca(CH3COO)2, the solution becomes warmer. This information indicates that if the temperature of a solution is decreased:

◦ H will become negative.
◦ H will become zero.
◦ the solubility of Ca(CH3COO)2 will decrease.
◦ the solubility of Ca(CH3COO)2 will increase.
◦ the solubility of Ca(CH3COO)2 will not change.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time.

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.
