Question

there are water droplets on the outside of a clean beaker. two chemicals are added to the beaker. these chemicals react with each other. during the reaction, the water droplets outside the beaker freeze. which statement best describes the reaction?
endothermic, because energy is absorbed
endothermic, because energy is released
exothermic, because energy is absorbed
exothermic, because energy is released

Explanation:

Endothermic reactions absorb energy from the surroundings. Since the water droplets outside the beaker freeze during the reaction, it means the reaction is absorbing heat from the surroundings (causing the water to lose heat and freeze). Exothermic reactions release energy to the surroundings.

Answer:

A. endothermic, because energy is absorbed
