What does one mean by exothermic and endothermic reactions? Give examples.
Exothermic reactions release heat, like methane combustion, respiration, carbon burning in oxygen, and organic decomposition. Endothermic reactions absorb heat, such as calcium carbonate decomposition, ferrous sulfate thermal decomposition, silver chloride decomposition, photosynthesis, and electrolysis of water. They require energy input, distinguishing them from exothermic reactions, which release energy.
