A 8.17 g sample of an unknown salt (MM= 116.82 g/mol) is dissolved in 150.00 g water in a coffee cup calorimeter. Before placing the sample in the water, the temps fire of the salt and water is 23.72 C. After the salt has completely dissolved, the temperature of the solution is 28.54 C. The temperature change of the solution is 4.82 C. Was the dissolution process endothermic or exothermic?

A) Endothermic because the water temperature increased.

B) Exothermic because the salt temps fire decreased.

C) exothermic because the water temperature increased.

D) endothermic because breaking an inimical bond requires energy
