The oxygen used in production; the oxygen used in medicine; the oxygen produced by electrolysis of water in the laboratory; they are all oxygen, but are there any differences between them? What I want is the difference between oxygen and oxygen in the three types of oxygen, such as (the difference between solid impurities and gas impurities)

The purity is different, the bacteria content is different, the water content is different.

With 160 g of oxygen, how much water is consumed and how much g of hydrogen is obtained when the experiment is carried out with electrolytic water? How much water and how many grams of hydrogen of hydrogen is available when 160 g of oxygen is tested with electrolytic water?
