Endothermic reaction - correct answer To break bonds, the surroundings need to give energy to the molecule. The bonds gains energy, as they take in energy so have a positive sign. The system loses energy so gets colder Exothermic reaction - correct answer To make bonds, the molecule give energy to the surroundings. The bonds lose energy, as they give out energy so have a negative sign. The system gains...
