Hydrocarbon (Fuel) + Oxygen (O2) → Carbon Dioxide (CO2) + Water (H2O) + Heat Energy
Here's a more detailed explanation:
When fossil fuels are burned, they react with oxygen from the air. The main component of most fossil fuels is carbon, so the primary product of combustion is carbon dioxide (CO2). Hydrogen is also present in fossil fuels, so water vapor (H2O) is another product of combustion.
The amount of CO2 and H2O produced depends on the specific hydrocarbon fuel being burned. For example, burning methane (CH4), the main component of natural gas, produces one molecule of CO2 and two molecules of H2O for every molecule of methane burned.
In addition to CO2 and H2O, burning fossil fuels also releases other pollutants into the atmosphere, including nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter.
The chemical equation for the complete combustion of methane is:
CH4 + 2O2 → CO2 + 2H2O + Heat Energy
Overall, the burning of fossil fuels is a chemical process that involves the reaction of hydrocarbons with oxygen to produce carbon dioxide, water vapor, and other pollutants, along with the release of heat energy.
