Methane (CH4) is a clean-burning fuel that is the
main constituent of natural gas, the type of gas piped into
homes. The combustion of methane (CH4) is similar
to that of hydrogen, though with methane, many more chemical
reactions take place before stable molecules form.
When ignited, a molecule of methane reacts with two
molecules of oxygen (O2). The end result is three
new molecules: two molecules of water (H2O) and
one of carbon dioxide (CO2).
