Question

endothermic reactions 4 examples

Answer 1

An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.

example:
melting ice cubes.
melting solid salts.
evaporating liquid water.
converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes)

Answer 2

PhotosynthesisMelting iceEvaporating liquid waterSublimation of carbon dioxide (dry ice)Cracking of alkanesThermal decomposition reactionsElectrolytic decomposition of sodium chloride into sodium hydroxide and hydrogen chlorideDissolving ammonium chloride in water
