Question

a reaction absorbs energy and causes the beaker to feel cold. * which statement best explains what happened? the molecules stopped moving the reaction released energy the reaction absorbed energy and was endothermic the reaction was exothermic

Explanation:

• In an endothermic reaction, energy is absorbed.
• When energy is absorbed from the surroundings (like the beaker), the surroundings feel cold.
• Molecules never stop moving (kinetic theory).
• Exothermic reactions release energy (would make the beaker feel warm).

Answer:

The reaction absorbed energy and was endothermic.
