Solution

The type of reaction that occurs when a substance reacts with oxygen to produce heat and light is called a combustion reaction. Here are the steps that describe this process:

  1. Identification of reactants: In a combustion reaction, the reactants typically include a substance (often a hydrocarbon, such as propane or butane) and oxygen.

  2. Reaction process: The substance reacts with oxygen in the air. This reaction is usually initiated with a spark or a flame.

  3. Energy release: As the reaction proceeds, it releases energy in the form of heat and light. This is why combustion reactions are exothermic.

  4. Formation of products: The products of a combustion reaction are typically water (H2O) and carbon dioxide (CO2), though the exact products can vary depending on the specific reactants and reaction conditions.

So, in summary, a combustion reaction is a type of chemical reaction where a substance combines with oxygen to produce heat and light, often resulting in a flame.
