Final answer:
The combustion of a hydrocarbon produces carbon dioxide, water, and energy. Propane is an example of a hydrocarbon used as a fuel, releasing heat energy upon combustion. The correct answer is D.
Step-by-step explanation:
The combustion of a hydrocarbon typically results in the formation of carbon dioxide, water, and energy. Hydrocarbons are compounds consisting only of carbon (C) and hydrogen (H) and are common fuels because their combustion releases significant amounts of heat energy. For example, propane (C3H8) is a gaseous hydrocarbon used in gas grills.
When a hydrocarbon combusts in the presence of oxygen (O₂), the chemical reaction produces carbon dioxide (CO₂) and water (H₂O) vapors, along with the release of energy. Thus, the correct answer to the student's question is 'd. Carbon dioxide, water, and energy'. The correct answer is D.
