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.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa.
