2. Exothermic reactions give off thermal energy (heat) and cause a rise in
temperature, while endothermic reactions are those that require energy and result in
a drop in temperature. Were any of the reactions you observed exothermic or
endothermic? Give evidence from your observations and the reasoning for your
answers. (5 points)
