Answer:

An exothermic reaction is defined as a reaction that releases heat and has a net negative standard enthalpy change. Examples include any combustion process, rusting of iron, and freezing of water.

Explanation:

An exothermic reaction is defined as a reaction that releases heat and has a net negative standard enthalpy change. Examples include any combustion process, rusting of iron, and freezing of water.

The combustion is an example of an exothermic reaction.

An exothermic reaction is a reaction that releases energy, this energy is usually in the form of heat. An endothermic reaction is a reaction that absorbs energy to take place.

Analyzing the given reactions we have that:

  • Evaporation: need to absorb energy to increase the kinetic energy of the molecules
  • Melting ice: need to absorb energy to increase the kinetic energy of the molecules
  • Combustion: releases energy after forming bonds between molecules
  • Decomposition: need to absorb energy to break molecule

So, the combustion is an example of an exothermic reaction.
