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.
