Oxygen does not have just one use.
For oxygen masks for firefighters, scuba divers etc
One gas is oxygen
An anaerobic function is one that does not use oxygen.
One could ask their friends if they have some information about oxygen bars. If one is interested in the effects of inhaling increased levels of oxygen, one could go to the library and look for books about the medical use of oxygen.
One should use 'ite' when naming an oxyanion with one less oxygen atom than the 'ate' form, and 'ate' when naming the oxyanion with the most oxygen atoms.
Aerobic organisms use oxygen.
To carry oxygen and carbon dioxide through the blood stream.
One way to convert carbon dioxide to oxygen in one step is through the process of photosynthesis, which occurs in plants. During photosynthesis, plants use sunlight to convert carbon dioxide and water into oxygen and glucose.
What do you mean? To test for oxygen being produced, light a splint, blow it out then put it over the object you beleve is producing oxygen and if the splint re-lights oxygen is being produced.
The fact that it does not use oxygen is precisely why it is anaerobic. Anaerobic means without oxygen. If it did use oxygen, it'll be called aerobic.
One way to test for the presence of oxygen gas is to use a glowing splint test. If the gas is oxygen, the glowing splint will relight when introduced into the gas due to oxygen's ability to support combustion.
