Ammonium nitrate and water are sometimes used to make instant cold packs. What kind of reaction is this? neither an exothermic nor an endothermic reaction an endothermic reaction both an exothermic and an endothermic reaction an exothermic reaction
OpenStudy (smilie2015):
it is an endothermic reaction. This reaction absorbs heat from the surroundings, quickly lowering the pack's temperatur
OpenStudy (noahbred):
so it lowers the tempters and exothermic increases the temp yah
OpenStudy (smilie2015):
yup endothermic lowers the temp . Endothermic means that they take in heat. So if the reaction is taking in all the heat, the heat is decreasing.
