Question

in a chemical reaction between potassium chloride (kcl) and water, the temperature decreases by 4°c. what type of reaction is this? endothermic unchanging in energy exothermic

Explanation:

Endothermic reactions absorb heat from the surroundings, causing the temperature to decrease. Since the temperature decreases in the reaction between KCl and water, it is an endothermic reaction.

Answer:

endothermic
