Here we look at how the combustion of hydrogen gas can lead
to a chain reaction.
On the face of it, the chemical reactions that take place in
the combustion of hydrogen are relatively simple: The
hydrogen molecules combine with oxygen molecules to form
water molecules, and energy is released in the process. The
equation for this reaction is this...
This equation doesn't show, however, all of the intermediate
reactions that lead to the formation of water. These
reactions can be initiated when a hydrogen atom is added to
hydrogen and oxygen molecules.
