Answer:

Well #"dioxygen gas"# for a start........................

Explanation:

And then some sort of combustible fuel; a good example is methane gas:

#CH_4(g) +2O_2(g) rarr CO_2(g) + 2H_2O(l) +Delta#

The energy released upon formation of strong #C=O# and #O-H# bonds is greater than the energy required to break (less) strong #C-H# and #O=O# bonds.

Of course, some means to initiate the reaction must be present, and modern gas stoves (usually) have an electronic ignition to start the cooking.
