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.
By the measurement of the nitrogen and oxygen levels in it.
One way to prove that air is in water is to observe the formation of bubbles when water is agitated or heated. These bubbles are composed of air that was dissolved in the water. Another method is to measure the oxygen or nitrogen content in water, which indicates the presence of air.
Well, Oxygen is in the air. You can prove that it is because we would all be dead. We breathe Oxygen. Answer - You can prove that Oxygen is in the air because without it we would die, and if you didn't already know, we are breathing it right now. Hoped This Helps :/ -Sara-
Yes, it is possible to prove that the clique problem is NP-complete.
To prove the hypothesis. To disprove the hypothesis.
plants produce oxygen
simply cover a burning candle with a glass to cut off the air, then the candle will burn out
Prove himself
It is not possible to prove something that is not true. The square of 2 is rational, not irrational.
If it reacted with oxygen then it would form water
Yes, nitrogen dioxide (NO2) is a polar molecule because it has a bent molecular geometry with a lone pair on the central nitrogen atom. This causes an uneven distribution of electrons, resulting in a slight negative charge on the oxygen atoms and a slight positive charge on the nitrogen atom.
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.
