Question

endothermic vs exothermic
chemical reactions involve changes in _. regarding energy, there are two types of reactions.
color the liquid in the beaker blue
color the liquid in the beaker red
what is an endothermic reaction?
an endothermic reaction _ energy to _ bonds. the energy is absorbed in the form of _ from the surroundings. as a result, the temperature of the surroundings goes _.
surroundings get cooler
what is an exothermic reaction?
an exothermic reaction _ energ when new bonds _. the energy released in the form of _ to the surroundings. as a result, the temperature the surroundings goes _.
surroundings get warmer

Explanation:

• For endothermic reactions: Breaking bonds requires energy input. The energy is absorbed as heat from the surroundings. When heat is taken away from the surroundings (like in an endothermic reaction), the temperature of the surroundings decreases.
• For exothermic reactions: Forming bonds releases energy. The energy is released as heat to the surroundings. When heat is added to the surroundings (like in an exothermic reaction), the temperature of the surroundings increases.

Answer:

• Endothermic reaction blanks: absorbs, break, heat, down
• Exothermic reaction blanks: releases, form, heat, up
