What type of reaction is characterized by the release of energy in the form of heat and light?

The type of reaction characterized by the release of energy in the form of heat and light is indeed a combustion reaction. In a combustion reaction, a substance (typically a hydrocarbon) reacts with oxygen, resulting in the production of carbon dioxide, water, and a significant amount of energy. This energy release is observable as heat and light, which is why combustion is often associated with flames.

Combustion reactions are typically exothermic, meaning they release energy to the surroundings. This is in contrast to endothermic reactions, which absorb energy. While oxidation-reduction reactions (redox) and neutralization reactions can also involve energy changes, it is specifically combustion that is well-known for producing heat and light as prominent characteristics. The exothermic nature of combustion, along with the visible flames, makes it a clear example of a reaction that produces significant energy.
