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,
a. delta H will become zero
b. the solubility of Ca(CH3COO)2 will increase
c. delta H will become negative
d. the solubility of Ca(CH3COO)2 will decrease
e. the solubility of Ca(CH3COO)2 will not change
