Which products result from the perfect combustion of natural gas or propane?

The perfect combustion of natural gas or propane primarily produces water vapour and carbon dioxide as the main products, along with heat and light energy. During this process, all the carbon in the fuel combines with oxygen to form carbon dioxide, while the hydrogen combines with oxygen to form water vapour.

This ideal combustion occurs when there is a sufficient supply of oxygen, which ensures that the fuels burn cleanly and completely, leaving little to no byproducts. The release of heat and light is also characteristic of combustion processes, making them exothermic reactions.

Water vapour and carbon dioxide are harmless if released into the atmosphere in moderate quantities, unlike incomplete combustion products such as carbon monoxide and soot, which are associated with inefficiency and pollution. This distinction highlights the importance of accurate combustion processes for both safety and environmental considerations.
