A variety of gases make up air. They are present in various percentages. In nature, oxygen is the second most prevalent element after nitrogen. Except for inert elements, oxygen gas easily forms compounds with the rest of the elements. The result is oxides. This gas's characteristic is what gives it commercial significance as well. The manufacturing industries use oxygen gas.
Manufacturers of oxygen plants have a market value and contribute significantly to the expansion of numerous other markets, including those for oxygen concentrators, medical oxygen cylinders, and air-oxygen blenders.
