Is it possible to prove that fire needs oxygen and not nitrogen?
EmmaKirkmanDavis
Yes. In a lab, light two pieces of wood on fire. Close one in a chamber that is fed pure oxygen and another in a chamber that is fed pure nitrogen. The fire that is fed pure oxygen will burn hotter and brighter. The one that is fed nitrogen will go out.

If it reacted with oxygen then it would form water
What test can prove that pond weed produces oxygen gas?
Bubble measurement is a test which can prove that pond weed produces oxygen gas. Pond weed releases oxygen and takes in carbon dioxide during the process of photosynthesis. The experimenter will find the outward-moving bubbles containing oxygen with which to oxygenate the plant in question's surrounding water.
