The type of reaction that takes place in the presence of oxygen and produces carbon dioxide and water is combustion.

Here's why:

* Combustion is a chemical process that involves the rapid reaction between a substance with an oxidant, usually oxygen, to produce heat and light.

* Oxygen is a key reactant in combustion.

* Carbon dioxide (CO2) and water (H2O) are the most common products of combustion, especially when the substance being burned is a hydrocarbon (like wood, propane, or gasoline).

Example:

The burning of methane (CH4), a hydrocarbon, in the presence of oxygen is a combustion reaction:

CH4 + 2O2 → CO2 + 2H2O + heat and light
