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

smilie2015 · Answer

it is  an endothermic reaction. This reaction absorbs heat from the surroundings, quickly lowering the pack's temperatur

noahbred · Answer

so it lowers the tempters and exothermic increases the temp yah

smilie2015 · Answer

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.
