Endothermic Chemical Reactions

the reaction of barium hydroxide octahydrate crystals with dry ammonium chloride
dissolving ammonium chloride in water the reaction of thionyl chloride (SOCl2) with cobalt(II) sulfate heptahydrate
mixing water and ammonium nitrate
mixing water with potassium chloride
reacting ethanoic acid with sodium carbonate
photosynthesis (chlorophyll is used to react carbon dioxide plus water plus energy to make glucose and oxygen)
