The Quiz: What kind of chemical reaction produces heat?
Combustion
Precipitation
Decomposition
Synthesis
In chemical combustion reactions, a substance reacts with oxygen to produce light and heat in the form of fire. One of the most common combustion reactions is, well, setting something on fire. Once it reaches its activation energy by getting hot enough, wood, for example, acts as a fuel and continuously reacts with the oxygen in the air to form a combustion reaction.
The correct answer to this quiz is Combustion.
