when calcium chloride was dissolved in water, the system released heat into the surroundings, the flask, and thus the flask felt hot. This is an example of an exothermic reaction.

calcium chloride chemical processes known as exothermic reactions result in heat production. We described the heat flow q as negative when heat is emitted from the system to its surroundings. Therefore, the H of reaction for exothermic processes is negative. Endothermic chemical reactions are those in which the reactants take in heat energy from the environment to create products. A cooling effect results from these events because they cause calcium chloride their immediate surroundings to become cooler. The local environment warms up as a result of an exothermic process that releases heat. A process known as endothermy removes heat from the environment and cools it.
