Answer
An exothermic reaction
Explanation
## Step1:A combustion reaction is a type of chemical reaction where a substance (usually a fuel) combines with oxygen to produce carbon dioxide and water.## Step2:Combustion reactions are exothermic, meaning they release heat energy. This is a key characteristic of combustion reactions.## Step3:The other options provided are:- Endothermic reaction: These reactions absorb heat from their surroundings.- Energy loss reaction: This is not a standard term in chemistry.- Thermal decomposition reaction: These reactions involve breaking down a compound into simpler substances using heat, but they do not necessarily involve oxygen or the release of energy.## Step4:Given the characteristics of combustion reactions, the correct answer is that they are exothermic reactions.#
