When you burn a fuel, several components besides the fuel itself are involved in the combustion process. Here are the main elements that get used up:
1. **Oxygen**: Combustion requires an oxidizing agent, typically oxygen from the air. During the burning process, oxygen reacts with the fuel to produce combustion products.
2. **Nitrogen**: Although nitrogen is mostly inert, when combustion occurs at high temperatures, some nitrogen from the air can react with oxygen to form nitrogen oxides (NOx), which are environmental pollutants.
3. **Water Vapor**: The combustion of hydrogen in the fuel with oxygen produces water vapor as a byproduct.
4. **Heat Energy**: While not a substance that gets used up, the process of combustion releases thermal energy, which is often harnessed for various applications, such as heating or powering engines.
5. **Other Reactive Gases**: Depending on the composition of the fuel, other gases such as carbon dioxide (CO2), carbon monoxide (CO), along with various hydrocarbons and particulate matter, can be produced.
6. **Air Particles**: If the combustion occurs in an environment where combustion isn't complete, unburned hydrocarbons and other particulates can also be released.
In summary, during combustion, the primary substances used up are fuel and oxygen, while byproducts include heat, water vapor, and various gases that can include carbon dioxide and nitrogen oxides.
