Introduction to Bond Energies (enthalpies)

Показать описание
Bond breaking = endo = energy absorbed = COLD
Bond making = exo = energy released = HOT
If a reaction is overall exothermic then more energy was released than absorbed.

(OK if red is the hot water tap and blue is the cold water tap - isn't red light low energy and blue light high energy?)

Thank you. You did a really good job of explaining this to my class.

you said that it was both an endothermic reaction and an exothermic reaction. Before you described the numbers you said the endothermic, bond breaking, was stronger than the exothermic but once you got the the numbers you said it was exothermic because that is how the math came out. Is it endothermic, exothermic, or just neutral?
