Chemical Demonstrations: A Handbook for Teachers of Chemistry; 1983. When ammonium nitrate (NH₄NO₃) or ammonium chloride (NH₄CL) is dissolved in water, heat is absorbed and the solution cools. An endothermic process or reaction absorbs energy in the form of heat ( endergonic processes or reactions absorb energy, not necessarily as heat). The endothermic separation of the ions will dictate the overall reaction, since the exothermic hydration of the ions will gfive off less energy. Introduction Endothermic reactions are accompanied by the absorption of heat. What are the names of Santa's 12 reindeers? Record in Data Table 2. 3. thanks. Endergonic, exergonic, exothermic, and endothermic. Measured changes in temperature can help us classify chemical reactions as either endothermic or exothermic. An easy way to remember the difference between these two reaction types is by their prefixes: endo- means to draw in, and exo- means to give off. According to Ref.2, during the explosion, following exothermic reaction would take place (hydrocarbon is represented by $\ce{CH2}$): in the reaction mentioned above,more energy is released than absorbed so the reaction is named exothermic.do not confuse the number of bonds formed with concept of energy.the bonds formed are actually more stable and release large amount of energy.
