Endothermic substance Endothermic substance A m m onium N itrate (N H 4N O 3) A m m onium nitrate is a chem ical com pound w ith the chem ical form ula N H 4N O 3. it is a w hite crystalline salt consisting of ions of am m onium nitrate, it is highly soluble in w ater as a solid starting tem p of w ater: 25.4 Final tem p of w ater: 22.1 C hange in w ater tem p: -3.3
Exothermic substance Exothermic substance Calcium chloride (cacl2) Calcium chloride is an ionic com pound of calcium and chlorine. It is highly soluble in w ater and it is deliquescent. It is a salt that is solid at room tem perature, and it behaves as a typical ionic halide. B eginning w ater tem p: 25.4 Final w ater tem p: 28.9 C hange in w ater tem p: + 3.5
Endothermic substance Endothermic substance Sodium chloride (N aC l) Sodium chloride (N aC l), com m only know n as salt, isone of the m ost abundant m inerals on E arth and an essential nutrient for m any anim als and plants.
