Which is an example of an exothermic reaction evaporation combustion decomposition melting ice

1 answer

An example of an exothermic reaction from the options you provided is combustion.

Combustion reactions release energy in the form of heat and light when substances, usually hydrocarbons, react with oxygen. In contrast, evaporation and melting ice are endothermic processes, where energy is absorbed from the surroundings. Decomposition reactions can be either exothermic or endothermic, depending on the specific reaction.
