In endothermic reactions the reactants have a less energy than the products . The difference between these two energy levels is the energy absorbed from the surroundings. It is represented in an energy level diagram as a vertical jump from a lower to a higher level - …

5. Give criteria in terms of temperature changes for exothermic and endothermic reactions. Exothermic reactions - release heat and feel “hot” to the touch Endothermic reaction - gain heat and feel “cold” to the touch 6. If 1.65 g of Cu(NO 3) 2 are obtained from allowing 0.93 g of Cu to react with excess HNO 3, what is the percent

Chemical reactions are processes in which the atoms of one or more substances are rearranged to form different chemical compounds. How to tell if a chemical reaction has occurred (recap): Temperature changes that can’t be accounted for. o Exothermic reactions give off energy (as in fire). o Endothermic reactions absorb energy (as in a cold pack).

reactions (respiration is only 40% efficient: 60% of increased respiration thus generates heat). No shivering. Adrenal and thyroid glands Glands secreteadrenaline and thyroxine respectively, which increases the metabolic rate in different tissues, especially the liver, so generating heat. Glands stop secreting adrenaline and thyroxine.
